MacDefender caused a malware crisis for the Mac back in June 2011. At the time it seemed like an epidemic, but then after a short round of update Whack-A-Mole with Apple, MacDefender seemed to disappear entirely. In fact, Apple last updated its malware definitions on June 18.
The last time I saw Mac Defender in the wild was on June 23rd. This nasty bit of Mac malware made life miserable for Apple and its support technicians for the entire month of May, before fading away in mid-June.
New information suggests that Russian authorities may have busted the group responsible for one of the biggest scourges that the Mac has ever seen.
But last week, Russian cops who raided ChronoPay’s offices in Moscow found otherwise. According to a source who was involved in the raid, police found mountains of evidence that ChronoPay employees were running technical and customer support for a variety of fake AV programs, including MacDefender.
The last release of MacDefender occurred on June 18. ChronoPay's offices are raided June 23. A coincidence perhaps, or Russian law enforcement saving Mac users from fake antivirus software.
This would be great news if it turns out to be true.
