UCSniff v2.4 in the wild

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

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.

Some useful features of UCSniff that have been combined together into a single package:
