UCSniff runs best on the BackTrack Linux OS, which can be downloaded from the Remote-Exploit site.

We used Ettercap as a base tool for UCSniff MitM code. Ettercap is a great security toolkit and it's our hope that UCSniff can be used in a similar fashion by researchers.

A Future version of UCSniff supporting Windows and H.264 Video capture is planned, along with H.323 support!

UCSniff Overview

UCSniff is an exciting new VoIP Security Assessment tool that leverages existing open source software into several useful features, allowing VoIP owners and security professionals to rapidly test for the threat of unauthorized VoIP and Video Eavesdropping. Written in C, and initially released for Linux systems, the software is freely available for anyone to download, under the GPLv3 license. Some useful features of UCSniff that have been combined together into a single package:

• Allows targeting of VoIP Users based on Corporate Directory and/or extensions
• Support for automatically recording private IP video conversations
• Automatically re-creates and saves entire voice conversations to a single file that can be played back by media players
• Support for G.722 and G.711 u-law compression codecs
• Support for H.264 Video codec
• Automated VLAN Hop and Discovery support
• A UC Sniffer (VoIP and Video) combined with a MitM re-direction tool
• Monitor Mode
• Sniffs entire conversation if only one phone is in source VLAN

Why??

UCSniff was created as a Proof of Concept demonstration tool and a method of creating awareness around VoIP/UC threats. It can be used by VoIP/UC Administrators to test their own VoIP Infrastructure in a pilot before vulnerabilities are rolled into production. It can also be used by security professionals as a method of convincing IT decision makers that security best practices should be applied to VoIP/UC in the same way that they are applied to other TCP/IP based, client-server applications.

In the future, it will be an after-thought to include automated VoIP VLAN Discovery and VLAN Hopping support in all VoIP Security assessment tools. Future versions of tools similar to VoIP Hopper will have the capability to automatically check for multiple vendor Voice VLAN ID discovery mechanisms, as a VVID "Discovery" scanning feature, Hop into the Voice VLAN, and wait for the user's direction on which attack to run. Practical, automated VoIP attacks can be selected from a menu. UCSniff combines several important capabilities that make this concept less thoeretical and more practical.
