ACK Tunneling Trojans

– Arne Vidstrom, arne.vidstrom@ntsecurity.nu
Summary

Trojans normally use ordinary TCP or UDP communication between their client and server parts. Any firewall between the attacker and the victim that blocks incoming traffic will usually stop all trojans from working. ICMP tunneling has existed for quite some time now, but if you block ICMP in the firewall you’ll be safe from that. This paper describes another concept, that I call ACK Tunneling. ACK Tunneling works through firewalls that don’t apply their rule sets on TCP ACK segments (ordinary packet filters belong to this class of firewalls).


Serve Cmd
This program is based off of netcat(thanks to Hobbit). This program allows multiple connections while netcat only allows one and is a bit easier to use. Run this program on any NT machine to open a remote shell on any port You can start the program hidden (/h) and also assign it what port to listen on(default is 2323). Type “srvcmd.exe /?” for help. Once the program is listening telnet into the computer on that port and you have a shell(cmd) environment waiting for you. The shell will have the same permissions as the user who started the program. If the shell is started with administrator access, you can do things like add users via the net command:
