Catalin Cimpanu, the Record:
A threat actor has published the phone numbers and account details for an estimated 533 million Facebook users —about a fifth of the entire social network’s user pool— on a publicly accessible cybercrime forum.
“This is old data that was previously reported on in 2019,” a Facebook spokesperson told The Record. “We found and fixed this issue in August 2019.”
Well that is a relief since everyone I know has gotten a new name, email address, and phone number since August 2019.
Sadly, this is now the standard response to data breaches — state that you've bolted the stable door, move on. Any fallout is the user's problem, not theirs.
