"The downside of course is that the malware creators would need to have a lot of time on their hands to go through hours of Skype audio files to find anything juicy."

...unless of course its not the malware creators that are listening to the mp3s, but some algorithym looking for certain keywords in the files, preparing the files for later review.

i guess the government wouldn't need mp3s to eavesdrop on some/everyones skype conversations?

Skype IS/USES VoIP (Voice over Internet Protocol)...

"Skype uses a proprietary Internet telephony (VoIP) network", from the great source of Wikipedia

So most of your comment makes little sense. What product are you suggesting is taking over? It, as with all IP, will get hit by those wanting to abuse as soon as it becomes popular.

Skype is getting boring and attracts more and more spammers each day.
Most people are moving to Voip anyway, as it's far cheaper and more easy to use.
Skype had it's time, it will die soon as Voip is taking over rapidly.

The name of this trojan is "Megapanzer". It was named by the guy who wrote it and released its source.

Why Symantec insists on coming up with its own name, I can only speculate about. Perhaps they feel it'll boost their publicity to come up with yet another Silly.name.with.Dots.in?
