“The attackers already controlled a set of accounts, which were connected to Facebook friends. They used an automated technique to move from account to account so they could steal the access tokens of those friends, and for friends of those friends, and so on, totaling about 400,000 people,” said Facebook’s VP of Product Management, Guy Rosen in a blog post.
These access tokens made hackers able to steal name and contact information. The details stolen include phone number and/or emails of 15 million people. For another 14 million people:
“this included username, gender, locale/language, relationship status, religion, hometown, self-reported current city, birthdate, device types used to access Facebook, education, work, the last 10 places they checked into or were tagged in, website, people or Pages they follow, and the 15 most recent searches.”
You can check to see if you were in either of these categories by clicking on this link while logged into Facebook. There is a box that says whether hackers stole your data or not, what they took, and additional information about how to proceed.
Facebook first came under fire when the Cambridge Analytica scandal was revealed.
