Skype Trojan Can Log VoIP Conversations

Posted by timothy on from the sans-malice-would-be-a-useful-thing dept.

Slatterz writes "Security giant Symantec claims to have found the public release of source code for a Trojan that targets Skype users. Trojan.Peskyspy is spyware which records a voice call and stores it as an MP3 file for later transmission. An infected machine will use the software that handles audio processing within a computer and save the call data as an MP3. The file is then sent over the internet to a predefined server where the attacker can listen to the recorded conversations."

      Yep. Apparently some news site picked it up a week later and wrote their own article without the original details, making it front page news all over again. The only thing new is that Symantec gave it a goofy name.

    It appears that a guy named Ruben Unteregger published the source code on his site at http://www.megapanzer.com/source-code/#skypetrojan

    According to his site, he removed a plugin system from the source as well as code to bypass firewalls, but he'll add it back in at a later date.

    From looking at the source, this is heavily geared toward Windows, so the current iteration of the source doesn't affect OS X at this time.

      Yes, you may remember the recent Slashdot discussion on this exact topic.

    Does this affect the Mac OS X version, or does at least one of the callers have to be on a PC?

    It's written for Windows, like usual, and at least one of the callers would have to be infected.

    There are a lot of automated banking by phone facilities that rely on the user entering their account numbers and passwords via the keypad. An attacker won't even need sophisticated speech recognition software - all they need is software looking for DTMF tones.
