It’s easy to hack VOIP

Dial up VOIPAt least that’s what UK based VOIP expert Peter Cox, demonstrated with his Siptap software, which is able to “monitor multiple Voice-over-IP (VoIP) call streams, listening in and (record) them for remote inspection as .wav files.” Run on a test network, the application was able to extract sensitive information from a normal VoIP conversation. Still proof-of-concept, the experiment would probably have to be run on a wider scale to really demonstrate that it can work though.

The lack of privacy in VoIP connections is nothing new though, as anyone with a bit of networking knowledge can access packets of a VoIP flow from an unencrypted network and easily eavesdrop on a conversation. That’s why VoIP users need to make sure they follow a few steps to guarantee a minimum of privacy while chatting away. The best is to set up an encrypted network and just make sure you’re not giving away private information when you’re talking over VoIP.
