How to infect a Computer with a Virus or Trojan

Bind 2 exes (infect a game or any other .exe with your virus/trojan)
A simple thing to do is bind a game with the virus or trojan , lets say you have game.exe and server.exe , there are some programs that will add server.exe into game.exe , so when the program connects those two files it gives you a file.exe that will have both game and server in it , send it to your friends and say its just a game , binder is the program you need to connect these file.

Send them a downloaderA downloader will automaticaly download AND execute any file from the internet on the victims computer as soon as they open the downloader,here it goes:a downloader is 2-4 Kb only! it can be added in a game.exe with the way above,you have to upload your trojan/virus on a server lets say geocities then you set up the downloader to download and run this file,you send the 4Kb file to the victim and as soon his computer runs the file it starts downloading the trojan/virus from geocities,the victim will see nothin, the VIR SCANNERS CANT SEE IT BUT they will detect the trojan/virus that it will download.

Infected webpage (.EML Bug)Another way is to build a webpage that contains a virus and infects the visitors with explorer 5.01-5.5 versions with any virus , i havent test it yet and i am not sure if and how it works but i have seen programs around that promt you to choose a trojan/virus then it decodes it and the it gives you the html that contains the virus the problem is that it takes long time to decode it and its better if your virus is 1-30Kb other ways it ll take days to decode , as i said i havent test it yet and i wont be able to write more or reply to any emails askin for it.

Best way (if you have access on the victims pc)
Get a floppy disc and do the job

To Convert a FAT partition into NTFS

To convert a FAT partition to NTFS:

Click Start, click Programs, and then click Command Prompt.
In Windows XP, click Start, click Run, type cmd and then click OK.
At the command prompt, type CONVERT [driveletter]: /FS:NTFS.
Convert.exe will attempt to convert the partition to NTFS.

NOTE: Although the chance of corruption or data loss during the conversion from FAT to NTFS is minimal, it is best to perform a full backup of the data on the drive that it is to be converted prior to executing the convert command. It is also recommended to verify the integrity of the backup before proceeding, as well as to run RDISK and update the emergency repair disk (ERD).

Tips to create a Strong Password easily..!!!

How to create a Strong Password.
This lead me to explain the method I follow to set a password - A Strong Password indeed by all standards.
You must follow the following criteria while creating a Strong Password:
* The password must be a minimum of 8+ characters.
* The password must have 1 number , 1 special character, 1 Upper Case character.

A very simple example that I use to explain my friends and colleages is : P@ssw0rd. It fullfills all the criteria's. The 'a' is replaced by a special character @. The 'P' is of upper case. The 'o' is replaced by the numeral 0.
Well, you can now convert your regular password into a Strong Password by following a few changes like the example I have mentioned above for the simple password - P@ssw0rd.

* Make the first character Upper Case.
* Change all 'a' in the password to the special character @.
* Change all 's' in the password to the special character $.* Change all 'l' in the password to the special character !.
* Change all 'o' in the password to the numerical 0.
* Change all 'i' in the password to the numerical 1.

How to bypass CD DRM Encryption??

DRM is an encryption manifest file which dissallows an individual who's purchased a CD which contains the DRM directly written into the actual Audio Disk. DRM stands for Digital Rights Management.

What's the cause for DRM Encryption?
DRM(Digital Rights Management) is to control the internets piracy of Audio files, mp3s for example.. on P2P (Peer To Peer) Clients, (A famous one is KaZaA) for non-3rd party use. Which this means that You can rip the audio to your computer, and listen to them only at your computer and nowhere else. Now there usually is an internal ripper provided by the CD itself, for you to burn the audio to another CD-R or whatever, but if you follow my howto it'll make things a lot simpler.
-What you need-

1: 6-ft. (182m)* Shielded Audio Cable, 1/8/11th's stereo miniplug, to 1/8/11th's stereo miniplug. Radio shack item # (42-2387A)
2: A CD Player.
3: The CD which has the DRM encryption.
4: A Computer with working Microphone input, and soundcard output.
5: An Audio editor such as Sonic Foundry Sound forge 6.0 or something like it.

Now, take the Audio chord and plug it into your CD player where you'd put your headphones, then take the other end and plug it directly into your CPU's microphone input.

Once that's done, open up your Audio Editor... click on File>New> Once the new layout has opened, click "Record" now once it has started to record, click Play on your CD Diskman. (Make sure you have your Sound on the Diskman to MAX output)

Now thats pretty much it... once the disk has been fully played and upstreamed to your audio editor... you can disect the Tracks and the name them on New Sound layouts, name the track... and save it as mp3. Becuase by default all audio editors save upstreamed tracks as .WAV format, and wav format is a relativelly enormus size as far as bytes are concerned. Remember, it's our right to do what we want with what we buy.

How to fasten up Windows XP..??

1. DISABLE INDEXING SERVICES:-
Indexing Services is a small little program that uses large amounts of RAM and can often make a computer endlessly loud and noisy. This system process indexes and updates lists of all the files that are on your computer. It does this so that when you do a search for something on your computer, it will search faster by scanning the index lists. If you don’t search your computer often, or even if you do search often, this system service is completely unnecessary. To disable do the following:

1. Go to Start
2. Click Settings
3. Click Control Panel
4. Double-click Add/Remove Programs
5. Click the Add/Remove Window Components
6. Uncheck the Indexing services
7. Click Next


2. OPTIMISE DISPLAY SETTINGS

Windows XP can look sexy but displaying all the visual items can waste system resources. To optimise:

1.Go to Start
2. Click Settings
3. Click Control Panel
4. Click System
5. Click Advanced tab
6. In the Performance tab click Settings
7. Leave only the following ticked:
- Show shadows under menus
- Show shadows under mouse pointer
- Show translucent selection rectangle
- Use drop shadows for icons labels on the desktop
- Use visual styles on windows and buttons


3. SPEEDUP FOLDER BROWSING:-

You may have noticed that everytime you open my computer to browse folders that there is a slight delay. This is because Windows XP automatically searches for network files and printers everytime you open Windows Explorer. To fix this and to increase browsing significantly:

1. Open My Computer
2. Click on Tools menu
3. Click on Folder Options
4. Click on the View tab.
5. Uncheck the Automatically search for network folders and printers check box
6. Click Apply
7. Click Ok
8. Reboot your computer


4. IMPROVE MEMORY USAGE:-

Cacheman Improves the performance of your computer by optimizing the disk cache, memory and a number of other settings.
NOTE: This program is shareware and some features require activation.
Once Installed:

1.Go to Show Wizard and select All
2.Run all the wizards by selecting Next or Finished until you are back to the main menu. Use the defaults unless you know exactly what you are doing.
3.Exit and Save Cacheman
4.Restart Windows



5. OPTIMISE YOUR INTERNET CONNECTION:-

There are lots of ways to do this but by far the easiest is to run TCP/IP Optimizer.

1. Download and install
2. Click the General Settings tab and select your Connection Speed (Kbps)
3. Click Network Adapter and choose the interface you use to connect to the Internet
4. Check Optimal Settings then Apply
5. Reboot



6. OPTIMISE YOUR PAGEFILE:-

If you give your pagefile a fixed size it saves the operating system from needing to resize the page file.

1. Right click on My Computer and select Properties
2. Select the Advanced tab
3. Under Performance choose the Settings button
4. Select the Advanced tab again and under Virtual Memory select Change
5. Highlight the drive containing your page file and make the initial Size of the file the same as the Maximum Size of the file.

Windows XP sizes the page file to about 1.5X the amount of actual physical memory by default. While this is good for systems with smaller amounts of memory (under 512MB) it is unlikely that a typical XP desktop system will ever need 1.5 X 512MB or more of virtual memory. If you have less than 512MB of memory, leave the page file at its default size. If you have 512MB or more, change the ratio to 1:1 page file size to physical memory size.



7. SPEEDUP FOLDER ACCESS - DISABLE LAST ACCESS UPDATE:-

If you have a lot of folders and subdirectories on your computer, when you access a directory XP wastes a lot of time updating the time stamp showing the last access time for that directory and for ALL sub directories. To stop XP doing this you need to edit the registry. If you are uncomfortable doing this then please do not attempt.

1. Go to Start and then Run and type “regedit”
2. Click through the file system until you get to “HKEY_LOCAL_MACHINE\ System\CurrentControlSet\Control\FileSys
tem”
3. Right-click in a blank area of the window on the right and select ‘DWORD Value’
4. Create a new DWORD Value called ‘NtfsDisableLastAccessUpdate’
5. Then Right click on the new value and select ‘Modify’
6. Change the Value Data to ‘1′
7. Click ‘OK’



8. MAKE YOUR MENUS LOAD FASTER:-

This is one of my favourite tweaks as it makes a huge difference to how fast your machine will ‘feel’. What this tweak does is remove the slight delay between clicking on a menu and XP displaying the menu.

1. Go to Start then Run
2. Type ‘Regedit’ then click ‘Ok’
3. Find “HKEY_CURRENT_USER\Control Panel\Desktop\”
4. Select “MenuShowDelay”
5. Right click and select “Modify’
6. Reduce the number to around “100″
7. This is the delay time before a menu is opened. You can set it to “0″ but it can make windows really hard to use as menus will open if you just look at them - well move your mouse over them anyway. I tend to go for anywhere between 50-150 depending on my mood.


9. IMPROVE XP SHUTDOWN SPEED:-

This tweak reduces the time XP waits before automatically closing any running programs when you give it the command to shutdown.

1. Go to Start then select Run
2. Type ‘Regedit’ and click ok
3. Find ‘HKEY_CURRENT_USER\ Control Panel\Desktop\’
4. Select ‘WaitToKillAppTimeout’
5. Right click and select ‘Modify’
6. Change the value to ‘1000′
7. Click ‘OK’
8. Now select ‘HungAppTimeout’
9. Right click and select ‘Modify’
10. Change the value to ‘1000′
11. Click ‘OK’
12. Now find ‘HKEY_USERS\ .DEFAULT\Control Panel\Desktop’
13. Select ‘WaitToKillAppTimeout’
14. Right click and select ‘Modify’
15. Change the value to ‘1000′
16. Click ‘OK’
17. Now find ‘HKEY_LOCAL_MACHINE\ System\CurrentControlSet\Control\’
18. Select ‘WaitToKillServiceTimeout’
19. Right click and select ‘Modify’
20. Change the value to ‘1000′
21. Click ‘OK’


10. IMPROVE SWAPFILE PERFORMANCE:-

If you have more than 256MB of RAM this tweak will considerably improve your performance. It basically makes sure that your PC uses every last drop of memory (faster than swap file) before it starts using the swap file.

1. Go to Start then Run
2. Type “msconfig.exe” then ok
3. Click on the System.ini tab
4. Expand the 386enh tab by clicking on the plus sign
5. Click on new then in the blank box type”ConservativeSwapfileUsage=1″
6. Click OK
7. Restart PC


11. ENSURE XP IS USING DMA MODE:-

XP enables DMA for Hard-Drives and CD-Roms by default on most ATA or ATAPI (IDE) devices. However, sometimes computers switch to PIO mode which is slower for data transfer - a typical reason is because of a virus. To ensure that your machine is using DMA:

1. Open ‘Device Manager’
2. Double-click ‘IDE ATA/ATAPI Controllers’
3. Right-click ‘Primary Channel’ and select ‘Properties’ and then ‘Advanced Settings’
4. In the ‘Current Transfer Mode’ drop-down box, select ‘DMA if Available’ if the current setting is ‘PIO Only’

Registry Hacking

Display legal notice on startup:
Wanna tell your friends about the do's and dont's in your computer when they login in your absence. Well you can do it pretty easily by displaying a legal notice at system start up.
REGEDIT
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system]
"legalnoticecaption"="enter your notice caption"
"legalnoticetext"="enter your legal notice text"

Automatic Administrator Login:
Well here's the trick which you can use to prove that Windows XP is not at all secure as multi-user operating system. Hacking the system registry from any account having access to system registry puts you in to the administrator account.
REGEDIT 4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"AutoAdminLogon"="1"

No Shutdown:
Wanna play with your friends by removing the shutdown option from start menu in their computer.
Just hack it down !!!
Regedit
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
"NoClose"="DWORD:1"

Menu Delays:
Another minor and easy tweak to remove any delay from menus sliding out. For this you will need to use regedit (open regedit by going to Start -> Run..., then typing 'regedit' and pressing enter). The key you need to change is located in HKEY_CURRENT_USERControl PanelDesktop. The actual key is called MenuShowDelay - all you have to do is change the value to 0. Remember, you will have to re-boot your computer for this tweak to take effect.

GPEDIT.MSC And Autoplay
A great tweaking file that comes with XP is gpedit.msc.
Go to Start -> Run... and then type in 'gpedit.msc' and press enter.
This is effectively the Policies Editor, and it comes in handy often.
For example, if you hate CD autoplay like I do and want to permanently disable it, you can use this tool to do so.
Just run gpedit.msc, then go to Computer Configuration -> Administrative Templates -> System. In here you can see the value 'Turn Off Autoplay'. Right-click on it and then click 'Properties'.

Increasing options in add/remove programs:
Not a fan of MSN Messenger? don't want Windows Media Player on your system? Fair enough, but if you go to Add/Remove Programs in the Control Panel, by default none of Windows XP's 'built in' programs are visible. it's fairly easy to change, though... just open the file X:\Windows\inf\sysoc.inf (where X: is the drive letter where Windows XP is installed) in Notepad. You should see a section of the file something like this:


[Components]
NtComponents=ntoc.dll,NtOcSetupProc,,4
WBEM=ocgen.dll,OcEntry,wbemoc.inf,hide,7
Display=desk.cpl,DisplayOcSetupProc,,7
Fax=fxsocm.dll,FaxOcmSetupProc,fxsocm.inf,,7
NetOC=netoc.dll,NetOcSetupProc,netoc.inf,,7
iis=iis.dll,OcEntry,iis.inf,,7
com=comsetup.dll,OcEntry,comnt5.inf,hide,7
dtc=msdtcstp.dll,OcEntry,dtcnt5.inf,hide,7
IndexSrv_System = setupqry.dll,IndexSrv,setupqry.inf,,7
TerminalServer=TsOc.dll, HydraOc, TsOc.inf,hide,2
msmq=msmqocm.dll,MsmqOcm,msmqocm.inf,,6
ims=imsinsnt.dll,OcEntry,ims.inf,,7
fp_extensions=fp40ext.dll,FrontPage4Extensions,fp40ext.inf,,7
AutoUpdate=ocgen.dll,OcEntry,au.inf,hide,7
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7
RootAutoUpdate=ocgen.dll,OcEntry,rootau.inf,,7
IEAccess=ocgen.dll,OcEntry,ieaccess.inf,,7

This is a list of all components installed at the moment. I've taken the example of MSN Messenger - the program entry called 'msmsgs', third-last line. You can see the word 'hide' highlighted - this is the string which tells Windows not to display the component in the Add/Remove Programs list. Fix this up by simply deleting the word 'hide' like so:

msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7

To this:

msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,,7

Now, after restarting, you should be able to see MSN Messenger in the Add/Remove Programs list. If you want to be able to quickly view and remove all components, simply open the sysoc.inf file and do a global find and replace for the word ",hide" and replace it with a single comma ",".
Automatically Kill Programs At Shutdown:
don't you hate it when, while trying to shut down, you get message boxes telling you that a program is still running? Making it so that Windows automatically kills applications running is a snap. Simply navigate to the HKEY_CURRENT_USERControl PanelDesktop directory in the Registry, then alter the key AutoEndTasks to the value 1.

Speeding Up Share Viewing:
This is a great tweak. Before I found it, I was always smashing my head against the table waiting to view shares on other computers. Basically, when you connect to another computer with Windows XP, it checks for any Scheduled tasks on that computer - a fairly useless task, but one that can add up to 30 seconds of waiting on the other end - not good! Fortunately, it's fairly easy to disable this process. First, navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace in the Registry. Below that, there should be a key called {D6277990-4C6A-11CF-8D87-00AA0060F5BF}. Just delete this, and after a restart, Windows will no longer check for scheduled tasks - mucho performance improvement!

Create a Shortcut to Lock Your Computer
Leaving your computer in a hurry but you don’t want to log off? You can double-click a shortcut on your desktop to quickly lock the keyboard and display without using CTRL+ALT+DEL or a screen saver. To create a shortcut on your desktop to lock your computer: Right-click the desktop. Point to New, and then click Shortcut. The Create Shortcut Wizard opens. In the text box, type the following: rundll32.exe user32.dll,LockWorkStation Click Next. Enter a name for the shortcut. You can call it "Lock Workstation" or choose any name you like. Click Finish. You can also change the shortcut's icon (my personal favorite is the padlock icon in shell32.dll). To change the icon: Right click the shortcut and then select Properties. Click the Shortcut tab, and then click the Change Icon button. In the Look for icons in this file text box, type: Shell32.dll. Click OK. Select one of the icons from the list and then click OK You could also give it a shortcut keystroke such CTRL+ALT+L. This would save you only one keystroke from the normal command, but it could be more convenient.

How to Stop Hackers (How To Catch A Hacker)

Some one wrote this great Post at orkut about Catching Hackers

I don't know who exactly the writer of this great post is...
Here is what he had to write :

"just wrote this guide to give you some tips of which you may not have heard yet. Hopefully, it won't come to a hacker getting in, but if it does...

Tip 1: Hackers cover their tracks. Experienced hackers cover them more thorougly, but amateur hackers sometimes leave things behind. Don't expect them to leave any really big evidence behind; expect more of little things here and there you might find surprising. For example, if you're writing a term paper and a black hat hacker accidently saved it when he took a paragraph out- that's suspicious. Where did that paragraph go? Well, for one thing, now you know he was in that area. Check the folders surrounding the file- you might find something.

Tip 2: Decipher between the type of hackers that are attacking you. Experienced hackers will have a more in depth look around when they penetrate your system. They won't touch much because they know that that won't add too much to their knowledge. But if you know a hacker's been in, and some files are messed with, and you have a log of someone guessing passwords to a file or something of that sort, its probably some newbie who's just starting out. These are the easiest hackers to catch. They usually get so caught up in thoughts like "I'm in!" that they forget the basics, such as work behind a proxy.

Tip to protect yourself
My friend was setting up a webserver once. His first time too, and he wasn't to anxious to set up some good software to protect against hackers and viruses. He didn't put up one IDS, and before you know it, the obvious happened. But this time, a newbie had struck. The nice log files showed, bluntly across the screen, multiple instances of a foreign IP address that stood out. Some stupid newbie had tried to login as "uucp" on my friend's XP computer, with a password of "uucp." Well, that's great, but he also had tried the same user/pass combination three times, enough to get himself logged nicely. Even a semi-brainless user with some form of neurological system knows that uucp isn't a default XP account. Again, excitement toiled this hacker's brain, and maybe if he hadn't done that, along with a few other stupid things, he wouldn't have gotten caught. What other things did he do? Well, lets see. He openned 35 instances of MS-DOS. He tried to clean the printer's heads, and he edited a .gif in notepad. Then he uninstalled a few programs and installed some html editor, and replaced four files with the words "14P." he might as well have posted his phone number. In a few days, we had tracked him down to a
suburban town in Ohio. We let him go, not pressing any charges, because he had done nothing really damaging and had provided me with an example of a moron for this guide.


Tip 3: Don't go crazy if you lose data. Chances are, if it was that important, you would have backed it up anyway. Most hackers nowadays wish they were back in 1989 when they could use a Black Box and having a Rainbow Book actually meant something. Most hackers aren't blackhat, they are whitehat, and some even greyhat. But in the end, most hackers that are in systems aren't satisfied by looking around. From past experiences, I have concluded that many hackers like to remember where've they been. So, what do they do? They either press delete here and there, or copy some files onto their systems. Stupid hackers (yes, there are plenty of stupid hackers) send files to e-mail addresses. Some free email companies will give you the IP of a certain e-mail address's user if you can prove that user has been notoriously hacking you. But most of the time, by the time you get the e-mail addy it's been unused for weeks if not months or years, and services like hotmail have already deleted it.

Tip 4: Save information! Any information that you get from a log file (proxy server IP, things like "14P", e-mail addresses that things were sent to, etc.) should be saved to a floppy disk (they're not floppy anymore, I wish I could get out of the habit of calling them that) incase there's a next time. If you get another attack, from the same proxy, or with similar e-mail addresses (e.g: one says Blackjack 123@something.whatever and the other says Black_jack_45@something.znn.com) you can make an assumption that these hackers are the same people. In that case, it would probably be worth the effort to resolve the IP using the proxy and do a traceroute. Pressing charges is recommended if this is a repeat offender.

Tip 5: Don't be stupid. If you've been hacked, take security to the next level. Hackers do talk about people they've hacked and they do post IPs and e-mail addresses. Proof? Take a look at Defcon Conventions. I've never gone to one, but I've seen the photos. The "Wall of Shame"-type of boards I've seen have IPs and e-mail addresses written all over them in fat red, dry-erase ink. Don't be the one to go searching the Defcon website and find your e-mail address posted on the Wall of Shame board!

Tip 6: Don't rely on luck. Chances are, sometime or another, you're going to be targeted for an attack. Here you can rely on luck. Maybe they'll forget? Maybe they don't know how to do it? If you think this way, a surprise is going to hit your face very hard. Another way you could stupidly rely on luck is by saying this: It's probably just a whitehat. On the contrary, my friend, it's probably just a blackhat. A blackhat with knowledge stored in his head, ready to be used as an ax. It's your data. You take the chance.

How Internet Cookies Work

Internet cookies are incredibly simple, but they are one of those things that have taken on a life of their own. Cookies started receiving tremendous media attention starting in February 2000 because of Internet privacy concerns, and the debate still rages.

On the other hand, cookies provide capabilities that make the Web much easier to navigate. The designers of almost every major site use them because they provide a better user experience and make it much easier to gather accurate information about the site's visitors.
We will take a look at the basic technology behind cookies, as well as some of the features they enable. You will also have the opportunity to see a real-world example of what cookies can and cannot do using a sample page.

Cookie Basics
In April of 2000 I read an in-depth article on Internet privacy in a large, respected newspaper, and that article contained a definition of cookies. Paraphrasing, the definition went like this:
Cookies are programs that web sites put on your hard disk. They sit on your computer gathering information about you and everything you do on the Internet, and whenever the web site wants to it can download all of the information the cookie has collected.
Definitions like that are fairly common in the press. The problem is, none of that information is correct. Cookies are not programs, and they cannot run like a program does. Therefore they cannot gather any information on their own. Nor can they collect any personal information about you from your machine.

Here is a valid definition of a cookie:
A cookie is a piece of text that a web server can store on a user's hard disk. Cookies allow a web site to store information on a user's machine and later retrieve it. The pieces of information are stored as name-value pairs.
For example, a web site might generate a unique ID number for each visitor and store the ID number on each user's machine using a cookie file.

If you use Microsoft's Internet Explorer to browse the web, you can see all of the cookies that are stored on your machine. The most common place for them to reside is in a directory called c:\windows\cookies. When I look in that directory on my machine, I find 165 files. Each file is a text file that contains name-value pairs, and there is one file for each web site that has placed cookies on my machine.

You can see in the directory that each of these files is a simple, normal text file. You can see which web site placed the file on your machine by looking at the file name (the information is also stored inside the file). You can open each file up by clicking on it.

For example, I have visited goto.com, and the site has placed a cookie on my machine. The cookie file for goto.com contains the following information:
UserID A9A3BECE0563982D www.goto.com/

What goto.com has done is stored on my machine a single name-value pair. The name of the pair is UserID,and the value is A9A3BECE0563982D. The first time I visited goto.com, the site assigned me a unique ID value and stored it on my machine.

[Note that there probably are several other values stored in the file after the three shown above. That is housekeeping information for the browser.]

The vast majority of sites store just one piece of information -- a user ID -- on your machine. But there really is no limit -- a site can store as many name-value pairs as it likes.
A name-value pair is simply a named piece of data. It is not a program, and it cannot "do" anything. A web site can retrieve only the information that it has placed on your machine. It cannot retrieve information from other cookie files, nor any other information from your machine.


How Does Cookie Data Move?

As you saw in the previous section, cookie data is simply name-value pairs stored on your hard disk by a web site. That is all that cookie data is. The web site can store the data, and later it receives it back. A web site can only receive the data it has stored on your machine. It cannot look at any other cookie, nor can it look at anything else on your machine.

The data moves in the following manner:
If you type the URL of a web site into your browser, your browser sends a request to the web site for the page. For example, if you type the URL http://www.netcrackers.blogspot.com into your browser, your browser will contact Blogger's server and request its home page.
When the browser does this, it will look on your machine for a cookie file that Blogger has set. If it finds a Blogger cookie file, your browser will send all of the name-value pairs in the file to Blogger's server along with the URL. If it finds no cookie file, it will send no cookie data.
Blogger's web server receives the cookie data and the request for a page. If name-value pairs are received, Blogger can use them.
If no name-value pairs are received, Blogger knows that you have not visited before. The server creates a new ID for you in Blogger's database and then sends name-value pairs to your machine in the header for the web page it sends. Your machine stores the name-value pairs on your hard disk.
The web server can change name-value pairs or add new pairs whenever you visit the site and request a page.
There are other pieces of information that the server can send with the name-value pair. One of these is an expiration date. Another is a path (so that the site can associate different cookie values with different parts of the site). You have control over this process. You can set an option in your browser so that the browser informs you every time a site sends name-value pairs to you. You can then accept or deny the values.

How Do Web Sites Use Cookies?

Cookies evolved because they solve a big problem for the people who implement web sites. In the broadest sense, a cookie allows a site to store state information on your machine. This information lets a web site remember what state your browser is in. An ID is one simple piece of state information -- if an ID exists on your machine, the site knows that you have visited before. The state is, "Your browser has visited the site at least one time", and the site knows your ID from that visit.

Web sites use cookies in many different ways. Here are some of the most common examples:
Sites can accurately determine how many readers actually visit the site. It turns out that because of proxy servers, caching, concentrators and so on, the only way for a site to accurately count visitors is to set a cookie with a unique ID for each visitor. Using cookies, sites can:
->Determine how many visitors arrive
->Determine how many are new vs. repeat visitors
->Determine how often a visitor has visited

The way the site does this is by using a database. The first time a visitor arrives, the site creates a new ID in the database and sends the ID as a cookie. The next time the user comes back, the site can increment a counter associated with that ID in the database and know how many times that visitor returns.

Sites can store user preferences so that the site can look different for each visitor (often referred to as customization). For example, some sites offer you the ability to change content/layout/color. It or allows you to enter your zip code and get customized weather information.
Most sites seem to store preferences like this in the site's database and store nothing but an ID as a cookie, but storing the actual values in name-value pairs is another way to do it.

Ecommerce sites can implement things like shopping carts and "quick checkout" options. The cookie contains an ID and lets the site keep track of you as you add different things to your cart. Each item you add to your shopping cart is stored in the site's database along with your ID value. When you check out, the site knows what is in your cart by retrieving all of your selections from the database. It would be impossible to implement a convenient shopping mechanism without cookies or something like it.
In all of these examples, note that what the database is able to store is things you have selected from the site, pages you have viewed from the site, information you give to the site in online forms, etc. All of the information is stored in the site's database, and a cookie containing your unique ID is all that is stored on your computer in most cases.

An Example

To give you a simple example of what cookies and a database can do, We can take the example of Verizon.com They have created a simple history and statistics system for there articles. There system runs on the Verizon servers and lets you view your activity on the Verizon site. Here's how it works:
When you visit Verizon for the first time, the server creates a unique ID number for you and stores a cookie on your machine containing that ID. For example, on the machine I am using now, this is what I see in the Verizon cookie file:
user 35005 www.verizon.com/
There is nothing magic about the number 35,005 -- it is simply an integer that they increment each time a new visitor arrives. I was user number 35,005 to come to the Verizon site since this cookie system was installed. We could make the ID value as elaborate as we desire -- many sites use IDs containing 20 digits or more.

Now, whenever you visit any page on Verizon, your browser sends your cookie containing the ID value back to the server. The server then saves a record in the database that contains the time that you downloaded the page and the URL, along with your ID.
To see the history of your activity on Verizon, you can go to this URL on the site:
http://www.verizon.com/history.php
Your browser sends your ID value from the cookie file to the server along with the URL. The history.php page runs a piece of code that queries the database and retrieves your history on the site. It also calculates a couple of interesting statistics. Then it creates a page and sends it to your browser.

Try the URL for the history page now:
http://www.verizon.com/history.php

Then go view a couple of other pages on Verizon and try it again. You will see that the statistics change and so does the list of files.


Problems with Cookies

Cookies are not a perfect state mechanism, but they certainly make a lot of things possible that would be impossible otherwise. Here are several of the things that make cookies imperfect.
People often share machines -- Any machine that is used in a public area, and many machines used in an office environment or at home, are shared by multiple people. Let's say that you use a public machine (in a library, for example) to purchase something from an on-line store. The store will leave a cookie on the machine, and someone could later try to purchase something from the store using your account. Stores usually post large warnings about this problem, and that is why. Even so, mistakes can happen.
On something like a Windows NT machine or a UNIX machine that uses accounts properly, this is not a problem. The accounts separate all of the users' cookies. Accounts are much more relaxed in other operating systems, and it is a problem.

If you try the example above on a public machine (in a library or school, for example), and if other people using the machine have visited Verizon, then the history URL may show a very long list of files.

Cookies get erased -- If you have a problem with your browser and call tech support, probably the first thing that tech support will ask you to do is to erase all of the temporary Internet files on your machine. When you do that you lose all of your cookie files. Now when you visit a site again, that site will think you are a new user and assign you a new cookie. This tends to skew the site's record of new versus return visitors, and it also can make it hard for you to recover previously stored preferences. This is why sites ask you to register in some cases -- if you register with a user name and a password, you can re-login even if you lose your cookie file and restore your preferences. If preference values are stored directly on the machine then recovery is impossible. That is why many sites now store all user information in a central database and store only an ID value on the user's machine.
If you erase your cookie file for Verizon and then revisit the history URL in the previous section, you will find that Verizon has no history for you. The site has to create a new ID and cookie file for you, and that new ID has no data stored against it in the database.

Multiple machines -- People often use more than one machine during the day. For example a machine in the office, a machine at home and a laptop for the road. Unless the site is specifically engineered to solve the problem, the result will be three unique cookie files on all three machines. Any site that I visit from all three machines will track me as three separate users. It can be annoying to set preferences three times. Again, a site that allows registration and stores preferences centrally may make it easy for me to have the same account on three machines, but the site developers must plan for this when designing the site.If you visit the history URL demonstrated in the previous section from one machine and then try it again from another, you will find that your history lists are different. This is because the server created two IDs for you on the two machines.
There are probably not any easy solutions to these problems, short of asking users to register and storing everything in a central database.

Why the Fury around Cookies?


If you have read the article to this point, you may be wondering why there has been such an uproar in the media about cookies and Internet privacy. You have seen in this article that cookies are benign text files, and you have also seen that they provide lots of useful capabilities on the web.

There are two things that have caused the strong reaction around cookies:
The first is something that has plagued consumers for decades but is now getting out of hand. Let's say that you purchase something from a traditional mail order catalog. The catalog company has your name, address and phone number from your order, and it also knows what items you have purchased. It can sell your information to others who might want to sell similar products to you. That is the fuel that makes telemarketing and junk mail possible.

On a web site, the site can track not only your purchases, but also the pages that you read, the ads that you click on, etc. If you then purchase something and enter your name and address, the site potentially knows much more about you than a traditional mail order company does. This makes targeting much more precise, and that makes a lot of people uncomfortable.

Different sites have different policies. Many companies have strict privacy policies and do not sell or share any personal information about customers with any third party except in cases where you specifically allow them to do so. Other companies aggregate information together and distribute it.
The second is new. There are certain infrastructure providers that can actually create cookies that are visible on multiple sites. Many firms use these companies to serve ad banners on their sites. These companies place small (1x1 pixels) GIF files on the site that allow them to load cookies on your machine. The companies can then track your movements across multiple sites. It can potentially see the search strings that you type into search engines (due more to the way some search engines implement their systems, not because anything sinister is intended). Because it can gather so much information about you from multiple sites, the companies can form very rich profiles. These are still anonymous, but they are rich.

One company then went one step further by acquiring another firm, it threatened to link these rich anonymous profiles back to name and address information -- it threatened to personalize them, and then sell the data. That began to look very much like spying to most people, and that is what caused the uproar. Some companies are in a unique position to do this sort of thing, because they serve ads on so many sites. Cross-site profiling is not a capability available to individual sites, because cookies are site specific.

Things you didn't know about Windows XP.....

You've read the reviews and digested the key feature enhancements and operational changes.
Now it's time to delve a bit deeper and uncover some of Windows XP's secrets.

1. It boasts how long it can stay up. Whereas previous versions of Windows were coy
about how long they went between boots, XP is positively proud of its stamina.
Go to the Command Prompt in the Accessories menu from the All Programs start button option,
and then type 'systeminfo'. The computer will produce a lot of useful info, including the
uptime. If you want to keep these, type 'systeminfo > info.txt'. This creates a file
called info.txt you can look at later with Notepad. (Professional Edition only).

2. You can delete files immediately, without having them move to the Recycle Bin first.
Go to the Start menu, select Run... and type 'gpedit.msc'; then select User Configuration,
Administrative Templates, Windows Components, Windows Explorer and find the Do not move
deleted files to the Recycle Bin setting. Set it. Poking around in gpedit will reveal
a great many interface and system options, but take care -- some may stop your computer
behaving as you wish. (Professional Edition only).

3. You can lock your XP workstation with two clicks of the mouse. Create a new shortcut
on your desktop using a right mouse click, and enter 'rundll32.exe user32.dll,
LockWorkStation' in the location field. Give the shortcut a name you like.
That's it -- just double click on it and your computer will be locked. And
if that's not easy enough, Windows key + L will do the same.

4. XP hides some system software you might want to remove, such as Windows Messenger,
but you can tickle it and make it disgorge everything. Using Notepad or Edit, edit the
text file /windows/inf/sysoc.inf, search for the word 'hide' and remove it. You can
then go to the Add or Remove Programs in the Control Panel, select Add/Remove Windows
Components and there will be your prey, exposed and vulne

Everything You wanted to know about FIREWALLS..!!

A firewall is basically something that protects the network from the Internet. It is derived from the concept of firewalls used in vehicles which is a barrier made of fire resistant material protecting the vehicle in case of fire. Anyway a firewall is best described as a software or hardware or both Hardware and Software packet filter that allows only selected packets to pass through from the Internet to your private internal network. A firewall is a system or a group of systems which guard a trusted network( The Internal Private Network from the untrusted network (the Internet.) To understand how a firewall works, firstly we need to understand how exactly data is transferred on the Internet.

The TCP\IP suite is responsible for successful transfer of data across a network both the Internet and the Intranet. The TCP\IP suite is a collection of protocols which are inter-related and interdependent and act as a set of rules according to which data is transferred across the network. A protocol can be defined as a language or a standard which is followed while transfer of data takes place.

A firewall relies on the source and destination IP and also the ports to control the packet transfer between the untrusted network and the trusted network. Firewalls can be classified into 3 types:

1. Packet Filter Firewalls
2. Application proxy Firewalls
3. Packet Inspection Firewalls

Packet Filter Firewalls
They are the earliest and the most criticized firewalls, which nowadays are not easily found. They are usually Hardware based i.e. Router Based (a router is a piece of device which connects two
networks together.) Whenever a Packet Filter Firewall receives a packet for permission to pass through, it compares the header information i.e. the source and destination IP address, and port number with a table of predefined access control rules If the header information matches, then the packet is allowed to pass else the packet is direct contact between the untrusted system and the trusted private system.
Such Firewalls can be fooled by using techniques like IP Spoofing in which we can change the source IP such that the firewall thinks that the packet has come from a trusted system which is among the list of systems which have access through the firewall.

Application proxy Firewalls
The shortcomings of the packet filter firewalls are addressed by the new type of firewalls developed by the DARPA. It was widely believed that the earlier type of firewalls were not secure enough as they allowed the untrusted systems to have a direct connection with the trusted systems. This problem was solved with the use of Proxy servers as firewalls. A proxy server which is used as a firewall are called application proxy servers. This kind of a proxy firewall examines what application or service (running on ports) a packet is meant for and if that particular service is available only then is the packet allowed to pass through and if the service is unavailable then the packet is discarded or dropped by the firewall.

Packet Inspection Firewalls
It can be also known as an extension of the Packet Filter Firewall. It not only verifies the source and
destination IP's and ports, it also takes into consideration or verifies that content of the data before passing it through. There are two ways in which this kind of a firewall verifies the data to
be passed:
State and Session.
In case of state inspection, an incoming packet is allowed to pass through only if there is a matching outward bound request for this packet. This means that the incoming packet is allowed to pass through only if the trusted server had requested for it or had sent an invitation for it.
In case of session filtering, the data of the incoming is not verified, but instead the network activity is traced and once a trusted system ends the session, no further packets from that system pertaining to that session are allowed to pass through.


All along you will come across many Firewalls on various systems, basically a
firewall can be established
or setup in two ways:

1. Dual-homed gateway
2. Demilitarized zone (DMZ)

In a dual homed gateway firewall, there is a single firewall with 2 connections, one for the trusted network and the other for the untrusted network.
In the case of a Demilitarized Firewall or a DMZ there are two firewalls, each with two connections, but there is a slight difference in the case of a DMZ setup.
In the case of a DMZ setup, there are two firewalls, the first having two connections, one leading to the untrusted network and the other leading to the host systems like the email server or the FTP server etc.
In the case of a Dual Homed Gateway the untrusted network is connected to the host systems (email and FTP servers etc) through a firewall and these host systems are connected to the internal private network. There is no second firewall between the host systems and the internal
private trusted network.
The basic structure of the DMZ setup declares it to be a more secure system as even if an attacker gets through the first firewall, he just reaches the host systems, while the internal network is protected by another firewall.

World of Registry

What is the Registry?
The Registry is the central core registrar for Windows NT. Each NT workstation for server has its own Registry, and each one contains info on the hardware and software of the computer it resides on. For example, com port definitions, Ethernet card settings, desktop setting and profiles, and what a particular user can and cannot do are stored in the Registry. Remember those ugly system INI files in Windows 3.1? Well, they are all included with even more fun stuff into one big database called the Registry in NT.

Always make sure that you know what you are doing when changing the registry or else just one little mistake can crash the whole system. That's why it's always good to back it up!

Backup and Restore:
Even with Windows 98, and Windows 95 you can not just backup the registry when you back up files. What you would need to do is run either: regedit32.exe (for NT) or regedit.exe and then click the registry menu, then click export registry. The next step is to click all, then pick the drive to back up onto (usually a removable drive like tape, floppy, cd, zip drive, jazz drive etc.) and then hit "ok". To restore a registry from a backed up version, enter the registry program the same way, click import registry and click the drive and path where the backup is and hit "ok". It will restore it back to the previous backed up settings and may require a reboot.

Note: registry backups are saved as .reg files, and they are associated with regedit as default. This means that once you double-click a .reg file, it's contents will be inserted into your own registry.
What is SAM?
SAM is short for Security Accounts Manager, which is located on the PDC and has information on all user accounts and passwords. Most of the time while the PDC is running, it is being accessed or used.

What do I do with a copy of SAM?


You get passwords. First use a copy of SAMDUMP.EXE to extract the user info out of it. You do not need to import this data into the Registry of your home machine to play with it. You can simply load it up into one of the many applications for cracking passwords, such as L0phtCrack, which is available from: http://www.L0phtCrack.com


Of interest to hackers is the fact that all access control and assorted parameters are located in the Registry. The Registry contains thousands of individual items of data, and is grouped together into "keys" or some type of optional value. These keys are grouped together into subtrees -- placing like keys together and making copies of others into separate trees for more convenient system access.

The Registry is divided into four separate subtrees. These subtrees are called
HKEY_CLASSES_ROOT
HKEY_CURRENT_USER
HKEY_LOCAL_MACHINE
HKEY_USERS
We'll go through them from most important to the hacker to least important to the hacker.


First and foremost is the HKEY_LOCAL_MACHINE subtree. It contains five different keys. These keys are as follows:
SAM and SECURITY - These keys contain the info such as user rights, user and group info for the domain (or workgroup if there is no domain), and passwords. In the NT hacker game of capture the flag, this is the flag. Bag this and all bets are off.
The keys are binary data only (for security reasons) and are typically not accessible unless you are an Administrator or in the Administrators group. It is easier to copy the data and play with it offline than to work on directly.

HARDWARE - this is a storage database of throw-away data that describes the hardware components of the computer. Device drivers and applications build this database during boot and update it during runtime (although most of the database is updated during the boot process). When the computer is rebooted, the data is built again from scratch. It is not recommended to directly edit this particular database unless you can read hex easily.

There are three subkeys under HARDWARE, these are the Description key, the DeviceMap key, and the ResourceMap key. The Description key has describes each hardware resource, the DeviceMap key has data in it specific to individual groups of drivers, and the ResourceMap key tells which driver goes with which resource.
SYSTEM - This key contains basic operating stuff like what happens at startup, what device drivers are loaded, what services are in use, etc. These are split into ControlSets which have unique system configurations (some bootable, some not), with each ControlSet containing service data and OS components for that ControlSet. Ever had to boot from the "Last Known Good" configuration because something got hosed? That is a ControlSet stored here.
SOFTWARE - This key has info on software loaded locally. File associations, OLE info, and some miscellaneous configuration data is located here.


The second most important main key is HKEY_USERS. It contains a subkey for each local user who accesses the system, either locally or remotely. If the server is a part of a domain and logs in across the network, their subkey is not stored here, but on a Domain Controller. Things such as Desktop settings and user profiles are stored here.

The third and fourth main keys, HKEY_CURRENT_USER and HKEY_CLASSES_ROOT, contain copies of portions of HKEY_USERS and HKEY_LOCAL_MACHINE respectively. HKEY_CURRENT_USER contains exactly would you would expect a copy of the subkey from HKEY_USERS of the currently logged in user. HKEY_CLASSES_ROOT contains a part of HKEY_LOCAL_MACHINE, specifically from the SOFTWARE subkey. File associations, OLE configuration and dependency information.
What are hives?
Hives are the major subdivisions of all of these subtrees, keys, subkeys, and values that make up the Registry. They contain "related" data.

All hives are stored in %systemroot%\SYSTEM32\CONFIG. The major hives and their files are as follows:
Hive File Backup File
HKEY_LOCAL_MACHINE\SOFTWARE SOFTWARE SOFTWARE.LOG
HKEY_LOCAL_MACHINE\SECURITY SECURITY SECURITY.LOG
HKEY_LOCAL_MACHINE\SYSTEM SYSTEM SYSTEM.LOG
HKEY_LOCAL_MACHINE\SAM SAM SAM.LOG
HKEY_CURRENT_USER USERxxx
ADMINxxx USERxxx.LOG
ADMINxxx.LOG
HKEY_USERS\.DEFAULT DEFAULT DEFAULT.LOG


Hackers should look for the SAM file, with the SAM.LOG file as a secondary target. This contains the password info.Hive File Backup File
HKEY_LOCAL_MACHINE\SOFTWARE SOFTWARE SOFTWARE.LOG
HKEY_LOCAL_MACHINE\SECURITY SECURITY SECURITY.LOG
HKEY_LOCAL_MACHINE\SYSTEM SYSTEM SYSTEM.LOG
HKEY_LOCAL_MACHINE\SAM SAM SAM.LOG
HKEY_CURRENT_USER USERxxx
ADMINxxx USERxxx.LOG
ADMINxxx.LOG
HKEY_USERS\.DEFAULT DEFAULT DEFAULT.LOG


Hackers should look for the SAM file, with the SAM.LOG file as a secondary target. This contains the password info.

For ease of use, the Registry is divided into five separate structures that represent the Registry database in its entirety. These five groups are known as Keys, and are discussed below:
HKEY_CURRENT_USER

This registry key contains the configuration information for the user that is currently logged in. The users folders, screen colors, and control panel settings are stored here. This information is known as a User Profile.
HKEY_USERS

In windowsNT 3.5x, user profiles were stored locally (by default) in the systemroot\system32\config directory. In NT4.0, they are stored in the systemroot\profiles directory. User-Specific information is kept there, as well as common, system wide user information.

This change in storage location has been brought about to parallel the way in which Windows95 handles its user profiles. In earlier releases of NT, the user profile was stored as a single file - either locally in the \config directory or centrally on a server. In windowsNT 4, the single user profile has been broken up into a number of subdirectories located below the \profiles directory. The reason for this is mainly due to the way in which the Win95 and WinNT4 operating systems use the underlying directory structure to form part of their new user interface.

HKEY_LOCAL_MACHINE

This key contains configuration information particular to the computer. This information is stored in the systemroot\system32\config directory as persistent operating system files, with the exception of the volatile hardware key.

The information gleaned from this configuration data is used by applications, device drivers, and the WindowsNT 4 operating system. The latter usage determines what system configuration data to use, without respect to the user currently logged on. For this reason the HKEY_LOCAL_MACHINE regsitry key is of specific importance to administrators who want to support and troubleshoot NT 4.

HKEY_LOCAL_MACHINE is probably the most important key in the registry and it contains five subkeys:
Hardware: Database that describes the physical hardware in the computer, the way device drivers use that hardware, and mappings and related data that link kernel-mode drivers with various user-mode code. All data in this sub-tree is re-created everytime the system is started.
SAM: The security accounts manager. Security information for user and group accounts and for the domains in NT 4 server.
Security: Database that contains the local security policy, such as specific user rights. This key is used only by the NT 4 security subsystem.
Software: Pre-computer software database. This key contains data about software installed on the local computer, as well as configuration information.
System: Database that controls system start-up, device driver loading, NT 4 services and OS behavior.

Information about the HKEY_LOCAL_MACHINE\SAM Key

This subtree contains the user and group accounts in the SAM database for the local computer. For a computer that is running NT 4, this subtree also contains security information for the domain. The information contained within the SAM registry key is what appears in the user interface of the User Manager utility, as well as in the lists of users and groups that appear when you make use of the Security menu commands in NT4 explorer.
Information about the HKEY_LOCAL_MACHINE\Security key

This subtree contains security information for the local computer. This includes aspects such as assigning user rights, establishing password policies, and the membership of local groups, which are configurable in User Manager.
HKEY_CLASSES_ROOT

The information stored here is used to open the correct application when a file is opened by using Explorer and for Object Linking and Embedding. It is actually a window that reflects information from the HKEY_LOCAL_MACHINE\Software subkey.
HKEY_CURRENT_CONFIG

The information contained in this key is to configure settings such as the software and device drivers to load or the display resolution to use. This key has a software and system subkeys, which keep track of configuration information.



Understanding Hives

The registry is divided into parts called hives. These hives are mapped to a single file and a .LOG file. These files are in the systemroot\system32\config directory.Registry Hive File Name
HKEY_LOCAL_MACHINE\SAM SAM and SAM.LOG
HKEY_LOCAL_MACHINE\SECURITY Security and Security.LOG
HKEY_LOCAL_MACHINE\SOFTWARE Software and Software.LOG
HKEY_LOCAL_MACHINE\SYSTEM System and System.ALT

Change the Start Button Text(not Vista tested)

In lieu of the hacker resource method. You can find that method by typing in "hacker resource"; "start button" in google.

Get a binary file editor(or hex editor) to alter critical Windows system file. Just do a quick search; the're everywhere. This method has been successfully tested on Windows 95, 98, ME, 2000 and XP and therefore should be quite safe.

You're going to be changing windows explorer so, please make a back up in case you mess up. "Explorer.exe" can usually be found in C:\WINDOWS for Windows 95, 98, Me & XP and C:\WINNT for Windows NT/2000. Copy/paste "Explorer.exe" into another directory, C:\BACKUP is my suggestion. Now, make another copy and name it something else. 'explorer2.exe or 'blowme.exe' will work just the same.

Find the file word "start". There should be quite a few of them named start so Use the search tool in the hex editor "Start" which is represented as "53 00 74 00 61 00 72 00 74" in hex values. This should find all the strings with this value. Becuase there are a lot of "Start" strings, keep looking until you find one located just above this text "There was an internal error and one of the windows you were using has been closed.".

Here's a list of offsets to help you find the right one.

Windows 98
Offset: 0x00028D6E - 0x00028D76
Windows NT4
Offset: 0x00028BEE - 0x00028BF6
Windows ME
Offset: 0x00033DDE - 0x00033DE6
Windows 2000
Offset: 0x0003860E - 0x00038616
Windows XP (Enhanced Start Menu)
Offset: 0x000412B6 - 0x000412BE
Windows XP (Classic Start Menu)
Offset: 0x0004158A - 0x00041592
Windows XP SP1 (Enhanced Start Menu)
Offset: 0x0004208E - 0x00042096
Windows XP SP1 (Classic Start Menu)
Offset: 0x0004259A - 0x000425A2


When you find the right one, just replace "Start" with five other characters. Yes, sorry, it can't be more than 5 characters. If you want less just fill it in with spaces.(A B C)

Put the changed "blowme.exe" in the Windows directory. Both 'explorer.exe' and 'blowme.exe' should be the same file size but have different modified dates.

Next step depends on your OS. Don't get these mixed up.

Windows 95, 98 & ME
Exit to DOS (or use a boot disk for Windows ME) and at the command prompt change to the Windows directory and rename "explorer.exe" to "explorer.old". Then copy the newly modified Explorer "blowme.exe" to "explorer.exe". Do a directory listing and confirm that "explorer.exe" has the most recent modified date and time. Restart the computer and Windows should reload along with the new Start button text.

Windows NT
First close any open applications and open a new Command Prompt window, then switch back to the GUI and open the Task Manager. Find the "explorer.exe" process and end it, you should now be left with only the command prompt and task manager. Switch back to the command prompt and change to the Windows directory, rename "explorer.exe" to "explorer.old", and copy the newly modified Explorer "blowme.exe" to "explorer.exe". Do a directory listing and confirm that "explorer.exe" has the most recent modified date and time. Switch back to Task Manager and launch a "New Task" called "explorer.exe" this should reload the shell along with your modified "Start" button.

Windows 2000 and XP
Open your registry editor and find the key [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]. Find the value named "Shell" and change it to equal the filename of the new explorer "blowme.exe". Exit your registry editor and restart Windows for the change to take effect. To reverse the change, modify the value of "Shell" and set it back to "explorer.exe".



(Default) REG_SZ (value not set)
Shell REG_SZ explorer1.exe

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon


If you have problems, just restore the backup.

Hacking' Coca Cola machines.

This will be a brief tutorial on hacking, if you can call it that, coca cola machines.

First off, the vending machines that you can do this on : Coke, Coca-Cola classic, Diet Coke/Coke light, Sprite, Dasani, Vanilla Coke, Cherry Coke, Fanta, Fresca, and any other products made by coke in the US, those are the ones I know of in the UK.

Pictures of the kind of machines this works on: This

Before you attempt this you might want to make sure that the machine your targeting has an LCD display saying something along the lines of "refreshing beverages", if not, your out of luck. Most of the newer vending machines will have this on.

Getting into the menu.

The buttons to select which drink you will be purchasing are all numbered, depending on how they are positioned. If they are vertical they will be numbered as follows -

[ 1 ]
[ 2 ]
[ 3 ]
[ 4 ]

However, If they are positioned horizontal they will be numbered like this -

[ 1 ][ 2 ][ 3 ][ 4 ]
[ 5 ][ 6 ][ 7 ][ 8 ]

And so on and so forth. The sequence used to get into the debug menu is [ 4 ][ 2 ][ 3 ][ 1 ]

Now you should notice that the debug menu says "Error", If this isn't the case, your target machine doesn't have a debug menu.

The debug menu

Once you are in the debug menu there is a number of options you have. We will discuss them soon.

Navigating the debug menu is relatively simple, the buttons are as follows -

[ 1 ] = Back
[ 2 ] = Up
[ 3 ] = Down
[ 4 ] = Select

Now to the options we have ;). On the debug menu there are CASH, SALE, VER, ERORR, and RTN.

Cash - Machine Sales
With this option we can view all the sales made by the machine and how much money has been made off each individual item. There are 10 or so different options available in here, I'm not too sure what they are but If someone else can post about it, that would be great.

Sale - Total Sale Count
The sale option displays how many beverages have been purchased from this machine. Not much we can do with this.

Ver - Machine Version (I believe.)
Selecting this option will make a pretty large combination of numbers and letters scroll across the LCD display. I'm not sure how many characters, I think it's 12 though.

Erorr - Error Log
Pretty straight forward, the error log of the machine. Column Jams, Vend, Char, Acce, door, bvall (sp?). And I think that's it, there isn't much you can do with this although if you press and hold button 4 for a few seconds, it will clear all logs.

Rtn - Exit.
Exit's the debug menu.

Now to the fun part

CPO - Coin Pay Out *
Selecting this option will allow you to get coins from the mechanism which you use to put money in to the machine. There are options with-in CPO that allows you to select which coins you want to dump. I've only ever found 2 machines with this option, 1 had £0 in it -_- and when I was browsing the other one the security guard came so I had to leave (Was in a mall :P).

Press select button 4 to enter mode and the lowest coin value dispensable will show on the display.
Press select button 2 or 3 to scroll through the different coin values available.
Press and hold select button 4 to dump the coins whose value is shown on the display.
Press select button 1 will return to "CPO".
Press select button 2 to scroll to the next routine.

PrIC - Change prices of drinks *
I've never used this section but I'd assume you would select the drink by navigating up and down, then select it, then change the price with the navigation buttons. Someone please correct me if they know otherwise.

Pass - Change the password *
I've never found a machine where this option is accessible but it allows you to change the pass from [ 4 ] [ 2 ] [ 3 ] [ 1 ]. .

Rely - Relay (I think.) *
I'd advise you not to try this one, unless your a malicious little bugger :P. Selecting this option will usually cause the machine to jam and become unresponsive.

Time - Change the machines time *
Allows you to set the machines time.

CCo - Correct Change Only *
Change whether or not the machine will only accept correct change.

Note: * = May not be available, If the person who operates the machine has it turned off for safety purposes.

How To Access Blocked Sites At School or College

I was screwing around with the command prompt one day in school, and realized I could access blocked sites, I decided to share because I like you guys.

1. Start>Run and type in cmd, if you don't have run on your start menu, read another school hacking tutorial to tell you how to access it.

2. Once your command prompt box opens, type "ping www.yoururlhere.com" (of course without the quotes.)

3.Press enter and you should see some numbers that looks like an IP address pop up, copy those numbers.

4. Open up your school internet browser, and type in those numbers that you copied in the command prompt. Now you can access your website!

How to Delete Others Myspace Accounts

This is a really bastard thing to do, or funny as hell depending on what side you’re on.
(One man’s terrorist is another’s freedom fighter no?)
So I’m assuming all that read this are reading purely for the educational aspect right?
(Say Yes)

Ok, to make this short, the flaw is simple. It’s not a flaw in myspace, but in the way it’s setup. It’s not really a flaw at all, but oh well. It’s just the same as a mailing list. You sign up with your email, and unsubscribe by sending an email to an unsubscribe address with “unsubscribe” in the text field. When someone wants to legitimately unsubscribe to myspace, they open the form that does such, and unsubscribe. All that does is send an email from you (your account) to an email address that myspace uses for deleting accounts.

All you need to do is send an email from the victim’s email, to the server email used for removing accounts. This is very easy to do, very, no elite shell code programming involved or anything else.

The email address that myspace uses for account deletion is. cancelaccount@myspace.com This email address is being protected from spam bots, you need Javascript enabled to view it

Wow who would have thought it?
When you do delete an account, if you look in the URL bar when you delete your own account, it shows the variable input used, and that’s how the email address was found.
So what a no brainer, replace it with someone else’s.

So, just spoof an email from the target, with subject: delete, body: delete account
To cancelaccount@myspace.com This email address is being protected from spam bots, you need Javascript enabled to view it

Well you’re wondering how to get someone else’s myspace email. There are limitless ways, but the easiest it to first, communicate with them via AIM or in person, and just tell them you have some funny pictures of them drunk at a party and you want to send them to him/her. They won’t resist. Just social engineer them.

Mitnick has written a great book on the subject, “Art of deception”.

Once you have there email send a spoofed email from there email, to cancelaccount@myspace.com This email address is being protected from spam bots, you need Javascript enabled to view it with the subject:delete and body delete account
I don’t think it matters what you put in the subject and body, since It’s automated I’m assuming, and it’s a computer that looks at those emails, not a person. If you don’t know how to send spoofed emails,


Go to Google and find a tutorial how to send spoofed emails to do such. You need to learn how to use Google if you want to play with computers. It is the best way to direct information other than reading books, or asking someone smarter than you who is willing to tell you. It’s really freaking simple. You connect to an SMTP server (use the one on your ISP) and issue it the commands to make and send an email.


That’s it, within 48 hours the account will be deleted.
It works 100%, I have tested it out 100%.
It is not instant; it takes up to 48 hours.
If you were really evil, you could write a script or program that scans Google for email address’s, and then take those outputted address’s and send the requests to delete Myspace accounts on them. This is wrong though so I don’t advise anyone doing such. Also what is funny is that in High School or Middle School, most clubs and crap have mailing lists. Get access to one of those lists and it’s almost 100% assumed that all the addresses on those lists are kids who have myspace accounts.

How to Search Rapidshare: Find and Download Movies, Softwares..ETC

Some of you might be thinking: How can I search RapidShare when they don't offer a search box on their site? Unlike many of its file hosting competitors, Rapidshare doesn't let users browse or search through files that have been uploaded onto its servers. It's a decidedly anti-sharing attitude in the Web 2.0 era, but that hasn't kept Rapidshare.com from taking 18th place out of 500 sites worldwide according to Alexa.

Luckily, the lack of a Rapidshare search engine doesn't have to keep you from finding the movies, software, videos, and music that you're looking for. Let's say you want to find Windows Vista wallpapers that are hosted on Rapidshare.

Simply go to Google, and type in "site:rapidshare.com vista wallpapers" without quotes. You'll get back four results that match your search (see below). You can do other searches by replacing "vista wallpapers" with the query of your choice, but remember to preface it with "site:rapidshare.com".





You can then copy and paste the URL (circled in red in the screenshot above) into a download manager like RapidLeecher or RapGet to streamline your download.




If u wnt to search Any Uploader Files Like ( Deejam )


Jus type this on google Search Bar

How to Build Your Own PC

This guide will show you how to construct a brand spanking new PC and where relevant I’ll try to point out where things may differ slightly when dealing with older machines. First up you’ll need a few tools of the trade before you can start putting anything together, you can usually buy kits from your local computer store which will have all you need to get going, but if you wish to buy things individually here are the main tools you’ll need.

• Anti-static wristband
• Head screwdriver
• Flathead screwdriver

Remember to wear your Anti-Static wristband when dealing with fragile things susceptible to static such as the CPU and RAM, you don’t have to wear it all the time but just as a precaution you may want to keep it on during the course of putting your PC together, if you accidentally fry your CPU or RAM you’ll be kicking yourself for quite sometime - so remember that wristband.

The Case

If you’ve purchased a fairly decent case it’ll have it’s own 250-300 watt power supply. Anything lower and you may run into trouble with devices not having enough power to work. It will have come with a set of screws don’t worry if you find yourself coming up short of a specific screw just try to place them out evenly so the device you're screwing in is secure, I just presume case companys are evil and are trying to deprive us of screws, however if you have some spare don’t worry - you haven’t missed anything. They will be for other devices you may want to add in later on. The side panels of the case should be easily removable by just taking out a couple of screws; both sides should then be able to slide off.

Now you should have a clear view of the inside of the case ready for you to start fitting things in.

The Motherboard

Depending on your type of case it will either be in a fixed position or have a tray which can slide out to attach the motherboard. If it is a fixed plate you will have to lay the case on its side to install the motherboard. Now you can screw in the spacer mounts, these are the screws your mother board will sit on try to spread them out evenly as the tray may have several holes for spacer screws to fit in and you only have so many spacers, this is dependant on different mother boards so remember to screw in the spacers in a position which will align with the holes on the motherboard.

Once you’ve aligned the holes in the motherboard with the spacers you can now screw down the motherboard.

The CPU (Central Processing Unit) and Cooler

To insert the CPU into the socket on the motherboard you will first have to raise the lever on the side of the socket.

The socket will have a pin slot missing and the processor will have a pin missing and will have the corner coloured or marked in some way to indicate that it is the corner you must align with the missing pin slot, once aligned properly the processor will fit in easily without any force needing to be applied, once the processor is in lower the lever on the side of the socket to lock the processor in place. If your processor has come with a thermal pad or thermal paste you will need to apply this to the top of the processor now this helps to transfer heat to the cooler, after you have done this you can place the cooler on top of the processor. On older motherboards the cooler will have clips that fix to the motherboard which will click into place, the newer coolers for P4 will simply have 2 levers on either side of the cooler. Raise these then place the cooler on top of the processor and lower the levers to lock the cooler in place. Make sure the cooler is firmly attached. If it comes loose it can cause serious damage and on older processors you can wave bye bye if this happens to your processor, though all modern processors will have some degree of thermal protection to prevent overheating.

Now connect the power.

The RAM (Random Access Memory)

The RAM is easy to install. Different types of RAM will have the notch in different positions. Make sure you have the right type of RAM for your motherboard - check your motherboard manual to ensure this. Presuming you're using the right kind of RAM, the notch at the bottom will line up with the key in the memory slot. Now line it up and carefully press the memory into the slot - a little force may need to be applied to get it to seat correctly in the slot then once the clips close your know its securely seated. When dealing with older RAM it may be necessary to insert it on an angle to get it to fit in correctly.

AGP (Advanced Graphics Port)

All good modern video cards will need to be seated in the AGP slot, if you're dealing with an older video card it may need to be seated in the PCI slot which we will cover later, the AGP slot will be brown in colour. You will need to remove the metal tab at the back of the case, if it’s a new case you can just break these off, afterwards though you will need to screw in or use a plastic clip to hold the metal tab in place. Only do this if you have broken off a tab and do not intend to place a PCI card there. Installing the graphics card is easy - simply insert it into the slot and make sure it is seated correctly then use a screw to hold it in place.

PCI (Peripheral Component Interconnect)

Installing PCI cards such as sound cards and network cards are the same as installing the graphics card. There will be several free slots for various PCI cards, try to space them out if possible to prevent heat build up in the system. Once you have installed a PCI card it is best not to remove it then place it in another slot as this can cause IRQ conflicts with some motherboards.

Floppy Disk

To install the disk drive simply slide it into the drive bay remembering to remove the plastic front panels first and removing any metal panels behind this by knocking them out. It will be the smaller of the drive bays and will be located nearer the bottom compared to the larger CD-ROM drive bays which will be located nearer the top. Once you have slid the Floppy disk drive in, secure it with screws.

HDD (Hard Disk Drive)

The HDD goes in a similar way as floppy disk but will be hidden behind the casing and is fixed into position in the exact same way as the floppy disk drive, except will only require 2 screws instead of four. Just remember to set the drive as you want it either master single or slave. This is done by changing the jumper settings at the back of the drive.

CD-ROM (Compact Disk-Read Only Memory)

Putting in the CD-ROM drive or CD-Writer is the same as putting in the HDD - just remember to use the fine threaded screws, also remember to first set the jumper settings to either slave or master bearing in mind you cannot have 2 masters.

Ribbon Cables

Ok so now everything you want is installed and you’re getting close to finishing up but first you will need to connect all the cables. There are two main ribbon cables - the 40 pin IDE cable for the hard disk and CD-ROM drive and the 34 pin cable for the floppy drive. Cables are always colour coded to show pin 1. Most drives also provide some kind of identification for pin 1. If you find that this is not the case, just remember that pin 1 is the one next to the power plug.

Drive Power Connectors

The drive power connection is the large 4 pin connection they can only fit in one way so don’t worry about plugging them in the wrong way around, a bit of force to ensure there fitting snugly may be needed. Just remember the floppy drive will use a smaller plug. The last plug is the larger ATX plug that plugs into the power socket on the motherboard.

Other Connections

For this part you may want to refer to your motherboard manual which will clearly point out where each plug goes, it will also have abbreviations on the motherboard to point out where each connection should be plugged in for example.

• RS, RE, RST or RESET: connect the two-pin Reset cable here.
• HD, HDD LED: these two pins connect to the cable for the hard disk activity LED.
• SP, SPK, or SPEAK: the loudspeaker output. It has four pins.
• PWR, PW, PW SW, PS or Power SW: power switch, the PC's on/off switch. The plug is two-pin.
• PW LED, PWR LED or Power LED: the light located on the front panel of the case lights up when the computer is switched on. It is a two pin cable.

If you find a light not working try reversing the plug.

One last check

Now your PC is completely assembled but you may want to make a last minute check of the system before turning it on. Make sure all cables are properly connected and that all devices are properly seated or screwed in, you may want to leave the case cover off when turning the PC on for the first time just in case something isn’t connected correctly. If you hear any beeps this will indicate that something is not correctly connected or seated.

Congratulations you can now feel the satisfaction from having put your own PC together.
