It looks as though Apple's Mac OS X users have seen their first significant outbreak of malware, with Dr Web researchers claiming that more than 600,000 Macs have been botted by the drive-by Trojan, BackDoor.Flashback.39. Since Macs make up only a small percentage of the PC market (60 million Macs vs 1.3 billion PCs), this would be roughly equivalent to the Conficker outbreak, according to F-Secure's chief research officer Mikko Hypponen.
Flashback's success has been assisted by the culture of denial that -- with Apple's encouragement -- exists in the Mac market. Most Mac users don't use anti-virus software because they believe that their machines are impervious to malware. This outbreak could make the Apple ecosystem more secure by encouraging more Mac users to defend their systems.
