Reports surfaced today stating that a small number of Apple's systems were hacked through the same zero-day Java exploit that Facebook's systems fell victim to in January. The source of the exploit is said to be the same as the one that managed to infect some of Facebook's systems. In the case of Apple, there is no evidence that any data was transmitted from Apple's systems.
"Apple has identified malware which infected a limited number of Mac systems through a vulnerability in the Java plug-in for browsers," the company said in a statement. "The malware was employed in an attack against Apple and other companies, and was spread through a website for software developers. We identified a small number of systems within Apple that were infected and isolated them from our network."
Apple has released an update to Mac OS X that will help protect customers from the malware. The update can be installed from the Software Update panel in the Mac App Store or downloaded directly from Apple's website.
The source of the Facebook and Apple hacks is said to be a mobile development website known as iPhoneDevSDK. It's likely that the site didn't know that they were infected as it is a fairly reputable site when it comes to mobile development. This is reportedly not the first time the site has had issues with malware.
