The publicly released Facebook user data is believed to be part of a 2019 "Add Friend" Facebook security bug exploited by hackers at the time.

The types of data include Facebook user mobile phone numbers, their Facebook ID, name and gender information.

Facebook acknowledged the public availability of the stolen data and shared a statement with the Associated Press.

"This is old data that was previously reported on in 2019We found and fixed this issue in August 2019," Facebook told the AP. Leaky databases, breaches and bugs dominated Facebook in 2019.

The actual data source for the records in these databases was Facebook.

Data sets, in this case Facebook profile data, can also be useful in other types of automated attacks, such as brute forcing or credential stuffing to achieve account takeover, he said.
