Facebook, without provocation from any outside source, admitted that their systems were hacked early last month when employees accidentally downloaded and installed viruses on company laptops.

“This attack occurred when a handful of employees visited a mobile developer website that was compromised,” Facebook’s security blog indicated. “The compromised website hosted an exploit which then allowed malware to be installed on these employee laptops.”

Though the attack was “sophisticated” and “well-thought out,” Facebook employees claim that no data was compromised during the attack and that a patch was released on February 1^st to fix the damage the malware caused. “Foremost, we have found no evidence that Facebook user data was compromised,” Facebook said.

There were other companies that also were victim to this malware, and Facebook is working with them to help determine the location and cause of the malware along with authorities.

If it can happen to Facebook, remember it can happen to you, and always make sure your antivirus and antimalware software is up to date.
