Skype Worm Making its Rounds
If I were to use Instant Messaging programs or a voip program to avoid long distance charges, I would use Skype. Its encrypted, so even if it gets intercepted by a network administrator or nosy hacker, they won’t know what’s being discussed. But there is a worm running around on Skype now.
Technically, its not a real worm- it requires that the user falls for the social engineering part of it, but plenty of people are indeed falling for it.
Bottom line is don’t open files that people send you in IM. More details are from Brian Krebs at the WaPo and from F-Secure’s Blog here.
