Fake AntiVirus Takes A Twist
In May of the second quarter, Mac OS X users were unexpectedly pummeled by a fake antivirus program known as Mac Defender.
Indeed, much to the chagrin of Mac users all over the world, the Fake AV programs that had plagued untold numbers of PC users had finally evolved to incorporate the Mac OS X platform. Similar to many Fake AV programs, the MacDefender malware infected users via malicious Web sites that made their way to the top of the Google Image search results through SEO poisoning attacks.
Users that clicked on the links were then offered a bogus security scan, and then subjected to a message alerting them (often falsely) that their computer was plagued with malware. The phony scan was followed by an offer to install a “free” antivirus product. Users who agreed to insall the software were asked to submit their administrator password. Once installed, the program required users submit credit card information to pay a fee from anywhere between $50 to $100.
