Hacking CMOS Password 

Step one: Get a screwdriver.



Step two: open up your victim i.e. your CPU.



Step three: remove the battery .



Step four: plug the battery back in after 30secs.







Alternate step three: many motherboards have a 3 pin jumper to reset the CMOS to its default settings. Look for a jumper close to the battery or look at your manual if you have one. For example, you might find a three pin device with pins one and two jumper. If you move the jumper to pins two and three and leave it there for over five seconds, it may reset the CMOS. Warning -- this will not work on all computers! Step five: Your victim computer now hopefully has the CMOS default settings. 11/15/08

Hacking Windows 98 

Easy Win 9x Breaking #1:



Step one: boot up your computer.







Step two: When the "system configuration" screen comes up, press the "F5" key. If your system doesn't show this screen, just keep on pressing the F5 key. If your Win 98 has the right settings, this boots you into "safe mode." Everything looks weird, but you don't have to give your password and you still can run your programs. Too easy! OK, if you want to do something that looks a little classier, here's another way to evade that new password.

Hacking Windows 98 

Easy Win 9x Breaking #2:



Step one: Boot up.











Step two: when you get to the "system configuration" screen, press the F8 key. This gives you the Microsoft Windows 95 Startup Menu. Step three: choose number 7. This puts you into MS-DOS. At the prompt, give the command "rename c:\windows\*pwl c:\windows\*zzz." Step four: reboot. You will get the password dialog screen. You can then fake out your friends by entering any darn password you want. It will ask you to reenter it to confirm your new password. Step five. Your friends are smart enough to suspect you just created a new password, huh? Well, you can put the old one your friends picked. Again come to MS-DOS -- to rename *.zzz back to *.pwl. step six: reboot and let your friends use their secret password. It still works! 11/15/08

Editing Registry 







Step one: Back up all your files. Have a boot disk handy. If you mess up the Registry badly enough you may have to reinstall your operating system. Step two: Run Regedit.exe Click on it. It brings up several folders: -HKEY_CLASSES_ROOT -HKEY_CURRENT_USER -HKEY_LOCAL_MACHINE -HKEY_USERS -HKEY_CURRENT_CONFIG -HKEY_DYN_DATA Step three: Get into one of these HKEY things. Let's check out CURRENT_USER by clicking the plus sign to the left of it. Play around awhile. You'll soon realize that Microsoft is babysitting you. All you see is pictures with no clues. Step four. Now act like real hackers. We are going to put part of the Registry where we can see and change anything. First click the HKEY_CLASSES_ROOT line to highlight it. Then go up to the Regedit menu bar. Click it, then choose Export Registry File. with extension .reg. 11/15/08

Editing Registry 













Step five. Open that part of the Registry in Word Pad. One way is to right click on it from Explorer. IMPORTANT WARNING: if you left click on it, it will automatically import it back into the Registry. If you were messing with it and accidentally left click, you could trash your computer big time. Step six: Read everything you ever wanted to know about Windows security that Microsoft was afraid to let you find out. Things that look like: [ [HKEY_CLASSES_ROOT\htmlctl.PasswordCtl.1] @="PasswordCtl Object" [HKEY_CLASSES_ROOT\htmlctl.PasswordCtl.1\CLSID] @="{EE230860-5A5F-11CF-8B11-00AA00C00903}" The stuff inside the brackets in this last line is an encrypted password controlling access to a program or features of a program such as the net censorship feature of Internet Explorer. Step seven: It isn't real obvious which password goes to what program. You can say delete them all! Of course this means your stored passwords for logging on to your ISP, for example, may disappear. Also, Internet Explorer will pop up with a warning that "Content Advisor configuration information is missing. Someone may have tried to tamper with it." This will look really bad. 11/15/08

Editing Registry 







Step eight (optional): Want to erase your surfing records? For Internet Explorer you'll have to edit HKEY_CURRENT_USER, HKEY_LOCAL_MACHINE and HKEY_USERS. You can also delete the files c:\windows\cookies \ mm2048.dat and c:\windows\cookies\mm256.dat. These also store URL data. Step nine. Import your .reg files back into the Registry. Either click on your .reg files in Explorer or else use the "Import" feature next to the "Export" you just used in Regedit. This only works if you remembered to name them with the .reg extension. Step nine: Oh, no, Internet Explorer makes this loud obnoxious noise the first time I run it and puts up a bright red "X" with the message that I tampered with the net nanny feature! It looks bad. Erase the Registry and its backups. These are in four files: system.dat, user.dat, and their backups, system.da0 and user.da0. Your operating system will immediately commit suicide.



Now, use bootable floppy and install windows98 again.



Now,your censorship program is not enabled. 11/15/08

Blocking Programs The Programs Blocks your System operations either blocking your RAM or any other device As example this code.  <script language="javascript"> while(1) { w1=window.open(); w1.document.write("

Mail Bombing Mail bombing means to send huge number of e-mails (may be hundreds thousands or million) to a single email account, so that the maximum space of account is filled up and owner of account can’t receive any new messages that come .if his inbox is filled with so many new useless messages, that he cannot even read the existing messages and deleting all the useless messages takes up a lot of valuable time.

11/15/08

26

Types of Mail bombing 

There are two types of mail bombing 1. Mass Mail Bombing. 2. List Linking.

Mass Mail Bombing:- In these method the victim’s inbox is flooded with a huge number of the same emails. List Linking:- In these method the victim’s inbox is subscribed to thousands of mailing list whose subjects are different. Note: The method of mail bombing now a days not in use because capacity of mail boxes is very big so, it is difficult.

Psychological Hacking 

Most of the hackers study the psychology of a computer user and use it for hacking. These hackers are very harm full and can be found anywhere in chat or discussion group etc. They email you saying that they want to gift you a heavy amount and take all your personal or credit card information for further scamming. Here is an good example on Psychology in hacking. In this example hacker's email address is [email protected] (not associated to any YAHOO official). Hacker sends a mail (in html format) to the user as a Yahoo. COM administrative official telling that Yahoo server had a technical failure due to which Yahoo User database is destroyed so you are requested to fill your personal information in given form to prevent Mail-box cancellation. In this way, when user submits the form given in the mail the information reaches to hacker's mail box, and you are hacked!!!. Do you want to try it to your friend? ,If yes then, compose an email with subject like "URGENT MAIL" or "NOTICE" etc. Select and Copy the code given below in the text area and paste it in message body of your mail and send it as HTML to your friend. But don't forget to replace [email protected] with your own email address and "Please enter your details in the given form" with your own message to your friend. 11/15/08

Ethics and Safety  

 





Don't ever maliciously hack a system. Do not delete or modify files unnecessarily, or intentionally slow down or crash a system. Don't use codes from your own home, ever! Period. Watch what you post. Don't post accounts or codes over open nets as a rule.They will die within days, and you will lose your new treasure. Don't play tricks to others, no matter how bad you hate them. Make the tracking of yourself as difficult as possible for others.
