Podcast: Tor peer-to-peer privacy could be hacked

In this edition of Security Wire Weekly, Andrew Christensen of FortConsult explains how the Tor peer-to-peer network can be hacked to track down user identities.

 

 

Andrew Christensen, a researcher with FortConsult, explains how the Tor peer-to-peer network of routers, which keeps IP addresses private, can be hacked to reveal user data. Tor is used to make Web browsing, publishing and instant messaging anonymous. The developers say the aim is to "defend against traffic analysis," which can inhibit privacy. But the FortConsult report suggests that users of Tor aren't as anonymous as they may think.
