Facebook is taking steps to protect its own users in the aftermath of an Adobe hack that affected tens of millions of customer accounts. The company is asking anyone that used identical login credentials across both services to change their Facebook password immediately. To identify users that may be at risk, Facebook’s engineers are combing through a publicly posted database that contains details on millions of Adobe accounts. If a match is discovered, Facebook displays a message that alerts users of a “security incident on another website unrelated to Facebook.” “Facebook was not directly affected by the incident, but your Facebook account is at risk because you were using the same password in both places,” the warning reads. If you’re among those affected, you’ll be asked to answer a few questions for verification purposes, after which you can enter a new (and hopefully unique) password.
