Another day, another Apple software update to battle the Flashback trojan. Java for OS X 2012-003 makes some tweaks to Java in OS X to remove “the most common variants of the Flashback malware.” It also hobbles Java applets, disabling any auto-executing commands. And if it’s switched on again, the software kicks in to disable it if no applets have run in a while.
It has been reported that Flashback has infected 600,000+ Mac computers, so it’s a pretty widespread problem. If you haven’t updated your Mac software in a while, this would be a good time to do it. Just hit up Software Update in your Apple menu or System Preferences to install it.
