  1. /* Windows remote RPC DCOM exploit
  2.  * Coded by oc192 
  3.  * 
  4.  * Includes 2 universal targets, 1 for win2k, and 1 for winXP. This exploit uses
  5.  * ExitThread in its shellcode to prevent the RPC service from crashing upon 
  6.  * successful exploitation. It also has several other options including definable 
  7.  * bindshell and attack ports.
  8.  * 
  9.  * Features:
  10.  *
  11.  * -d destination host to attack.
  12.  *
  13.  * -p for port selection as exploit works on ports other than 135(139,445,539 etc)
  14.  *
  15.  * -r for using a custom return address.
  16.  *
  17.  * -t to select target type (Offset) , this includes universal offsets for - 
  18.  *    win2k and winXP (Regardless of service pack)
  19.  *
  20.  * -l to select bindshell port on remote machine (Default: 666)
  21.  *
  22.  * - Shellcode has been modified to call ExitThread, rather than ExitProcess, thus 
  23.  *   preventing crash of RPC service on remote machine.
  24.  * 
  25.  *   This is provided as proof-of-concept code only for educational 
  26.  *   purposes and testing by authorized individuals with permission to 
  27.  *   do so.
