Reuters reported that the database appears to be the same set of Facebook-linked telephone numbers that has been circulating in hacker circles since January and whose existence was first reported by tech publication Motherboard, according to Alon Gal, co-founder of Israeli cybercrime intelligence firm Hudson Rock.

Reuters was not immediately able to vet the information, which was being offered by a leaker for a few euros’ worth of digital credit on a well-known site for low-level hackers.

The authenticity of at least some of the data was verified by Alon Gal on Saturday by comparing it against phone numbers of people he knew. Other journalists said they have also been able to match known phone numbers to the details in the data dump.

However, Facebook issued a statement saying the data was “very old” and related to issue that the social media site had fixed back in August 2019.
