Via email and public Twitter replies, I’ve seen reports from about a dozen or so DF readers who’ve been hit by thisAnd they all seem like typical DF readers — sophisticated, experienced, if not downright expert Mac usersIt’s not an epidemic, but it’s definitely real, and insidious.
So @gruber says FlashBack is “not an epidemic, but it’s definitely real, and insidious.” Erm, 600K infectionsNot an epidemic好了。
Which raises the question: What qualifies as an “epidemic”? Here’s a2009年石板故事,米歇尔·蔡和丹刚关于猪流感:
The CDC’s official definition of an epidemic is: “The occurrence of more cases of disease than expected in a given area or among a specific group of people over a particular period of time.” Since some diseases become more prevalent or lethal over time, while others become less severe, the CDC must adjust its statistical models to alter the definition of what’s truly more than expected.
With 600,000 infections in a user base of 60-70 million, that means roughly 1% of all Macs worldwide have been hit by this thing, which is capable of downloading additional malware at will[…]
By comparison, the single largest Windows-based infection ever was Conficker在它鼎盛时在2009年,它感染700万台电脑, or about 0.7% of the total Windows installed base.
我想说一个Mac恶意软件爆发更常见,在比例的基础上,比Windows有史以来最大的感染1毫无疑问比预期更多的情况下,因此,我错了:流行确实是正确的字吗Cause for hysteria? NoBut an epidemic? Yes.
