Facebook Targeted in ‘Sophisticated Attack’
(Reuters) - Facebook Inc said on Friday it had been the target of an unidentified hacker group, but it found no evidence that user data was compromised.
“Last month, Facebook security discovered that our systems had been targeted in a sophisticated attack,” the company said in a blog post posted on Friday afternoon, just before the three-day Presidents Day weekend. “The attack occurred when a handful of employees visited a mobile developer website that was compromised.”
The social network, which says it has more than one billion active users worldwide, also said: “Facebook was not alone in this attack. It is clear that others were attacked and infiltrated recently as well.”
Facebook declined to comment on the motive or origin of the attack.
A security expert at another company with knowledge of the matter said he was told the Facebook attack appeared to have originated in China.
