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).

Extracting Web Server Information using Telnet / by R a v e N
<===========================================================>
http://blacksun.box.sk

Welcome to yet another BSRF tutorial. This time, I will teach you most basic command in the HTTP protocol, and how it is possible to extract tons of web server information and other pieces of info using this command only and a telnet client.

Okay, you are about to learn what your browser does when you type in, say, blacksun.box.sk. First of all, it connects to blacksun.box.sk on port 80. If there is an answer on the other hand, which means that the port is open (the port is not closed or blocked by any filtering software, such as a firewall) and a TCP session can start, your browser would usually type this:
get url HTTP/1.1
(followed by a blank line)
