Facebook’s security discovered that its systems had been targeted last month in a sophisticated attack on its employee’s laptop but claimed that its users’ data was not compromised.
The 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,” said the social media networking site in a statement on Friday. However, Facebook insisted ot has “no evidence that Facebook user data was compromised in this attack,” but did not elaborate further.
Facebook also said it has identified a new attempt to bypass its built-in cyber defenses and took corrective mesaures to add new protections on February 1.
Since the attack used a third-party website, it is suspected that it might affect many other companies where similar hacking attempts were staged, said reports. It also helps attackers to hack the email and other ID information of users in other companies.
