Dan Goodin at El Reg writes about the notorious Koobface worm being ported to Mac. The worm spreads via social engineering sites such as Facebook and Twitter and uses a malicious Java applet to load a backdoor onto your computer. Goodin points out that the Mac virus gurus at Intego have proclaimed this a low threat, specifically because it requires that the victim say yes to a warning message.
But so does pretty much every Windows variant of Koobface, nearly all of which generally masquerade as some sort of video codec.
It remains to be seen whether Mac users will prove to be more wary than their Windows' cousins. If not, we can expect that about 1% of those Mac users who do encounter the newly revamped Koobface will click "Allow" and infect their computers.
Intego is calling the new Mac social engineering worm OSX/Koobface.A. SecureMac is calling it Trojan.OSX.Boonana.a. Regardless of what you call it, it's a good reminder to disable Java in your browser. Truly, for all the security headaches Java brings, it's almost never ever legitimately needed.
