Mac’s can’t get viruses.
I hear that all the time, but it’s simply not true. According to an announcement yesterday from Dr. Web, there are over 600,000 Macs infected with
the Flashback Trojan. The original variant posed as an Adobe Flash Installer (maybe Steve Jobs was right about “dirty flash“), the most recent targets a java vulnerability. The hole was patched by Oracle in February, but Apple didn’t send it our until earlier this week after news began to spread about the latest Flashback variant.
According to Dr. Web, the 57 percent of the infected Macs are located in the US and 20 percent are in Canada. Like older versions of the malware, the latest Flashback variant searches an infected Mac for a number of antivirus applications before generating a list of botnet control servers and beginning the process of checking in with them. Now that the fix for the Java vulnerability is out, however, there’s no excuse not to update—the malware installs itself after you visit a compromised or malicious webpage, so if you’re on the Internet, you’re potentially at risk.
If you think one of your machines may be infected, F-Secure has instructions on how to use the Terminal to find out. The below snipet shows a clean machine.
If you don’t want
to do this yourself, bring it in to the shop and we’ll check and fix it for free.
