Skype Trojan

A researcher for Sophos has created a Trojan for research and education purposes. This Trojan injects code into a .dll component of the skype application which then hooks into the send and receive of skypes API’s. This allows the Trojan to intercept the incoming and outgoing conversations being transmitted between callers and send this video and audio data back to the attacker. Worse yet the Trojan can deliver its payload if only 1 of the two parties are protected. This means that if your computer is protected but the person on the other end is not you can still have the words stolen literally right out of your mouth.
