MACDefender Taking Bite out of Apple

Mac DefenderMost Mac users have lived in pure eternal virus-free bliss for many years. But of course, as Macs have become known for their virus free platform, hackers have come a knockin’ and have finally blown the house down. Mac Defender, the latest and most successful attempt to implant malware onto Macs comes as MacProtector and MacSecurity as well.

The basic ploy of the malware was to redirect Mac users from legitimate sites to fake sites which then tell the user that their Mac is infected. To tell you the truth, even with my scrutiny of the slightest odd looking site, I probably would have click on the link and downloaded the “anti-virus” software had I not been one of the lucky ones to hear about it before it was my problem.

As with many malware attacks, the ultimate goal comes down to money. The attack goes after the user’s credit card information in the hopes of skimming their info for fraudulent purposes. Well, it wasn’t fraudulent until they stole the credit card. Who knows, it might have been a birthday present for the hacker’s girlfriend.

Luckily, for all of us, Apple posted yesterday that they will deliver a Mac OS X software update “that will automatically find and remove Mac Defender malware and its known variants.”

If you’re one of the unlucky few and can’t wait for the update, here are the step-by-step instructions for avoiding or manually removing the malware, which Apple was so kind to post to their latest entry. Make sure to visit the Apple website for updated information.
