According to the site “reseau et telecom” , Peter Cox have released a POC of VOIP sniffing. The techrepublic say that Mr Cox was inspired by Phil Zimmermann. However, since I wasn’t able to find the software I am not sure what is new under the sun with it. VOIP is known to be insecure since the beginning. For instance the tool Vomit (voice over misconfigured internet telephones was released in 2004. A nice framework in python was also presented in a conference this year. Sending data in clear is also not a specific problem to VOIP, POP3 email or MSN message are also send in clear. Maybe It is still not obvious because decoding VOIP stream requiers more knowlegde than plain text protocol.

The ex AT&T employee Klein, says on MSNBC that the NSA have a room at AT&T to network traffic. At the opposite of a famous french blog (I dont want to step in a polemic so I will not put a link here). I believe it is true. For me storage is not an issue because if flickr is able to store 20 000 more photos every hours why the NSA can’t coope with incoming traffic ? I assume that they only kept relevant data e.g not youtube video and of course not the same data twice that’s all. It is also common sense that this room is only for diverting traffic and that the traffic is analyzed and stored directly at the NSA. Since the 11th september, I guess that things are getting more easy for theses guys with the new laws.
Well at the end, it does not change anything as always there is two options
- Assume that you are watched and just don’t care
- Assume that you are watched and use crypto
