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).

Thanks for downloading cryptcat

This is a simple modification to netcat to add twofish encryption.
netcat was origianally written by the l0pht (hobbit and weld pond).

Intro:
In this tutorial I, FuX0reD, will try to do as much hand-holding and will
try to be as THOROUGH as possible, AND IT WILL BE IN PLAIN ENGLISH (for
those people who dont know, or dislike to speak in english). As easy as it
is to figure out, some people still end up screwin up somehow, and infecting
their own asses and end up being 0wned by some other llahmas, so try to
understand these features as well as possible If you have anything to add to
this tutorial or you find something I’ve missed, please email me at

EXE2HTML 1.0b Dox (C) 2000 by [ByteRage] —————————————-

 

What’s new in 1.0b
——————
– Fixed some bugs so that the program is looks less crappy πŸ™‚
– Better exploit code (Windows directory can be variable, a little smaller)

 

How does it work, what systems does it run on ?
———————————————–
EXE2HTML creates an HTML file that will use the HTA exploit to extract an EXE/JPG/etc…-file from an HTML file. According to Georgi Guninski, the exploit runs on all windows versions with Internet Explorer 5.0/5.1 on.


CIPE-Win32 v2.0-pre14 README

——————————————————————–

This package consists of a binary installation and a development
environment of and for CIPE-Win32 v2.0 beta. This document assumes
a working knowledge of CIPE and it’s installation requirements.

 

CIPE-Win32 is a port of Olaf Titz’s CIPE VPN software from Linux
to Windows NT.

 

This software implements a functional node in a CIPE network on
Windows NT4.0 SP3-SP6 and Windows 2000. I don’t know if any DOS-based
Window OS’S will work or Windows XP, others are welcome to attempt
installation.

 

I know this documentation is not “polished”. When the software is
working perfectly, I’ll do a nice HTML help system (unless someone
is willing to start it for me).

 

128 bit Blowfish encryption is supported at the moment. 128 bit IDEA
support is being worked on.
