How to crash someones computer on a windows 9x network -
In theory this technique should allow you crash anyone on your LAN (local area network, i.e. your office/college network) provided they are using Windows 9x (95/98/Millenium?). I am told that this will not crash computers running NT or 2k - although I have not been able to test this.
Has anyone heard of the "win98-con" or "con\con" crash? Well the general idea is this (I wonder how many of you will do this!!):
Go to start menu
Choose Run
Type "\con\con"
Ok, now I will pause for a little while so that the people who tried that have enough time to reboot their computers!! tum tee tum...
When you try to go to a place with \con\con in the name - boom! you will recieve the blue screen of death (the windows crash screen) and you will have to reboot. So trying to go to:
c:\con\con\crash.htm
will also crash the computer. This exploit is present in all versions of win 95 and 98. Have you ever tried to create a folder and call it 'con' ? - well try it...windows won't let you. This is because con is kind of like a "reserved" word. Con is not the only one though, there are a few more - but the only other one I can remember is 'Aux'. \aux\aux should also produce the desired effect.
I though this was pretty cool, especially to do to peoples computers when they aren't watching! But apprently it gets even better!
You can use this \con\con thing to crash any computer you like on a network using a small link in html code. There is one restriction though, the computer you are going to crash MUST have at least one shared directory. I will go more in depth into file sharing next volume. For now, to check whether a computer has a share you can use the Nbtstat.exe program (which comes with windows and runs in msdos).
To use Nbtstat to find out if a computer is sharing - in dos type:
Nbtstat -a <target computers IP>
If you get anything useful back, look at the column under says "Name". This is a list of the share names - which is what we are interested in.
Actually to be honest, its probably easier if you find out what shares are on your computer...since most networked computers are set up exactly the same. To find what shares you have, type:
Nbtstat -n
Once you have a share name, create a new web page, and place a link like the one below:
" Click here to Crash your target! "
( Except without the " )
You will have to modify that link above slightly:
Replace "target" with the name of the computer (or the IP? Haven't tried that...should work) you want to crash
Replace "share" with share name you found
Now load the web page up and click the link - you should see the targets computer screen turn blue!
Thats why it crashes.
