Facebook Hacked. Site Says User Data Not Compromised

In case you were away for the long weekend and missed it, on Friday Facebook.com announced via its website that it had been hacked:

"Last month, Facebook Security discovered that our systems had been targeted in a sophisticated attack. This attack occurred when a handful of employees visited a mobile developer website that was compromised. The compromised website hosted an exploit which then allowed malware to be installed on these employee laptops. The laptops were fully-patched and running up-to-date anti-virus software. As soon as we discovered the presence of the malware, we remediated all infected machines, informed law enforcement, and began a significant investigation that continues... We have found no evidence that Facebook user data was compromised."

This means that the old saying still applies: a chain is only as strong as its weakest link. In this case, your sensitive personal information on a social networking site is only as secure as the weakest (mobile or website) app developer.
