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
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.
