Federal Trojan’s Got A “Big Brother”

By Tillmann WernerAbout two weeks ago, the German Chaos Computer Club (CCC) has published an analysis report of a backdoor trojan that they claim had been used by German police during investigations in order to capture VoIP and IM communication on a suspect’s PC. Our friends over at F-Secure published a blog post last week where they wrote about another file that, according to them, seemed to be the dropper component of the trojan.

Mac-based malware is still a relatively rare occurrence when compared to the flood of malicious programs aimed at Windows. But, it appears that the attackers who are creating the more recent Mac malware either have experience writing Windows-based malware or are simply paying close attention to what’s been working for Windows malware for all of these years.

One security company is now laying out some of the details of a year-long observation of a large hacker forum.
