Details from more than 500 million Facebook users have been found available on a website for hackers
The availability of the data set was first reported by Business Insider. According to that publication, it has information from 106 countries including phone numbers, Facebook IDs, full names, locations, birthdates, and email addresses.
In December 2019, a Ukrainian security researcher reported finding a database with the names, phone numbers and unique user IDs of more than 267 million Facebook users — nearly all U.S.-based — on the open internet. It is unclear if the current data dump is related to this database.
“This is old data that was previously reported on in 2019,” the Menlo Park, California-based company said in a statement. “We found and fixed this issue in August 2019.”
