Skype flaw reveals users' location, file-downloading habits
Skype, the ever-popular VoIP service, has a flaw that allows malicious users to track other Skype users' location and p2p sharing activity. Apparently, you can obtain another user's IP address during a call, or even through a brief call without an answer.
"Even when a user blocks callers or connects from behind a Network Address Translation (NAT) -- a common type of firewall -- it does not prevent the privacy risk," according to a release from NYU-Poly.
