Facebook the target of a series of attacks
Facebook said on Friday that it been the target of a series of attacks by an unidentified hacker group, but it had 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.
“The attack occurred when a handful of employees visited a mobile developer website that was compromised.”
“Facebook was not alone in this attack. It is clear that others were attacked and infiltrated recently as well.”
Facebook said it spotted a suspicious file and traced it back to an employee’s laptop.
After conducting a forensic examination of the laptop, Facebook said it identified a malicious file, then searched company-wide and identified “several other compromised employee laptops.”
The company also said it identified a previously unseen exploit to bypass its built-in cyberdefenses, and that new protections were added on February 1.
