A Mac trojan called Flashback resurfaced in the news over the last week or so after it was revealed that 600,000+ Macs were infected by the nefarious botnet. We’ve showed you how to see if you’re infected by Flashback, and Apple has released two updates already to patch the malware.
Apple is about to get into the antivirus business, as the company has said that it is working its own tool for you to detect and remove Flashback once and for all. The folks in Cupertino will also be working with ISPs around the globe to hunt down the source of this botnet and kill it at the root.
A recent version of malicious software called Flashback exploits a security flaw in Java in order to install itself on Macs.
Apple released a Java update on April 3, 2012 that fixes the Java security flaw for systems running OS X v10.7 and Mac OS X v10.6. By default, your Mac automatically checks for software updates every week, but you can change that setting in Software Update preferences. You can also run Software Update at any time to manually check for the latest updates.
Apple is developing software that will detect and remove the Flashback malware.
In addition to the Java vulnerability, the Flashback malware relies on computer servers hosted by the malware authors to perform many of its critical functions. Apple is working with ISPs worldwide to disable this command and control network.
Apple also recommends disabling Java if you think you’re infected. As we’ve shown you before, it’s pretty easy to see if you’ve fallen prey to Flashback or not. As always, you’re safest on the most recent version of Mac OS X.
