/// Facebook Hacked, Claims "No Evidence of User Data Compromised"

February 15, 2013  |  All Things Digital

Facebook announced on Friday that it had been the target of a series of attacks from an unidentified hacker group, which resulted in the installation of malicious software onto Facebook employee laptops. “Last month, Facebook security discovered that our systems had been targeted in a sophisticated attack,” the company said in a blog post . “The attack occurred when a handful of employees visited a mobile developer website that was compromised.” Facebook said that these employees then had malware installed on their laptops as a result of their visiting the website. The hack used what is called a “zero-day Java exploit,” a known vulnerability in Oracle’s software which has gained much attention in recent months. Essentially, anyone visiting a website using this attack who also has Oracle’s Java enabled in their browser was vulnerable. As a result, hackers inserted malware onto the laptops of multiple Facebook employees. “As soon as we discovered the presence of malware, we remediated all infected machines, informed law enforcement, and began a significant investigation that continues to this day,” the post read. In the company’s post, Facebook notes that it had “found no evidence that Facebook user data was compromised.” Facebook did not say what the hackers did have access to, however, after the installation of said malware. Facebook’s announcement comes on the heels of a string of recent attacks on other major websites. Twitter, the microblogging social network that hosts more than 200 million active users on its service, announced it had been hacked two weeks ago, and that upward of 250,000 user accounts may have been compromised as a result. Other targets have included the Washington Post, the New York Times and The Wall Street Journal, all of which have said they believe that the Chinese government was somehow involved in their system infiltration. But both Facebook and Twitter, in their respective blog posts, made no accusation or direct comparison to the hacks made on the Times, the Journal or the Post.
