The idea that Macs don’t get viruses is now officially a thing of the past. Of course Mac malware has been around for years, but now a massive botnet has been discovered that takes this relatively small issue and makes it a widespread problem. While hackers indeed target Windows PCs far more frequently, a trojan horse virus discovered earlier this year has reportedly now been found to affect more that half a million Mac computers worldwide. Russian anti-virus vendor Dr. Web has discovered that malware called “BackDoor.Flashback.39” is currently present on at least 600,000 Macs. The trojan has the capability to use a java vulnerability to intercept passwords and other private data, and then transmit the information back to the person or group that deployed it. Apple has since patched the vulnerability, but security experts at F-Secure have published a simple guide to help Mac users determine whether or not they are infected, and then remove any malicious files from their computers that are tied to the Flashback trojan. A link to F-Secure’s guide can be found below.
