in brief Flashback could now be considered a pandemic larger than Conficker.
Blogger Ed Bott from ZDNet Australia's sister site ZDNet US has crunched the numbers and estimates that based on the 600,000 infected Macs, a number that has now been verified by a second research lab, about 1 per cent of all Macs have been infected.
If 1 per cent doesn't sound like much, it needs some comparison for scale. The largest infection to hit Windows machines was Conficker. Bott writes that although Conficker infected 7 million PCs at its prime, that represented 0.7 per cent of all Windows machines.
What that means is that users can, today, pick any Mac and it's more likely to be infected with Flashback than if, during Conficker's peak, they randomly selected a Windows machine and tested for Conficker. In other words, it's easier to target more Mac users than PC users.
What's worse is that Conficker took several years to evolve and, as of last year, still was responsible for about 1.7 million infections — Flashback only started targeting Macs relatively recently.
