One of the benefits
of Skype was that, due to the way it works (P2P, encrypted communications), it made it much more difficult to do any sort of wiretap. This has upset
who are used to having the ability to wiretap any voice communications. However, it's never impossible. The most obvious way is to simply create some sort of trojan that gets installed on one user's computer that has audio recording abilities -- and Symantec is going around hyping up the fact that source code for just such a trojan has been released
. Of course, even Symantec admits that there's no evidence of the code actually being used in the wild -- it seems more like a proof-of-concept. On top of that, it's hardly a new idea. Nearly a year ago, we talked about how German authorities were accused
of using something that sounded quite similar. Still, it is a good reminder that even if you're using an encrypted Skype call, at either end of that call, the audio is decrypted, and a well-placed recording system can capture it.
