Sad thing is Apple had months to patch the exploit that was used. It was well known that Apple was dragging their feet patching their version of Java, it was only a mater of time.
A year ago today, Apple released a software update to halt the spread of the Flashback worm, a malware strain that infected more than 650,000 Mac OS X systems using a vulnerability in Apple’s version of Java. This somewhat dismal anniversary is probably as good a time as any to publish some clues I’ve gathered over the past year that point to the real-life identity of the Flashback worm’s creator.
“This means Flashback is not only the most advanced, but also the most successful OS X malware we’ve ever seen,” wrote F-Secure’s Broderick Ian Aquilino.
The F-Secure writeup answers an important question not found in other analyses: Namely, what was the apparent intended purpose of Flashback? Put simply: to redirect Google results to third-party advertisers, all for the author’s profit. It’s name was derived from the fact that it spread using a social engineering trick of presenting the OS X user with a bogus Flash Player installation prompt. F-Secure notes that this same behavior — both the Flash social engineering trick and the redirection to fake Google sites that served search results for third-party advertisers that benefited the author — was also found in the QHost malware, suggesting that Flashback may have been the next evolution of the Mac QHost malware.
