Somebody has gotten their arms on a database stuffed with Fb customers’ cellphone numbers, and is now promoting that knowledge utilizing a Telegram bot, in line with a report by Motherboard. The safety researcher who discovered this vulnerability, Alon Gal, says that the one who runs the bot claims to have the data of 533 million customers, which got here from a Fb vulnerability that was patched in 2019.
With many databases, some quantity of technical talent is required to search out any helpful knowledge. And there usually needs to be an interplay between the individual with the database and the individual making an attempt to get data out of it, because the database’s “owner” isn’t going to only give another person all that helpful knowledge. Making a Telegram bot, nonetheless, solves each of those points.
Few days in the past a consumer created a Telegram bot permitting customers to question the database for a low charge, enabling folks to search out the cellphone numbers linked to a really massive portion of Fb accounts.

The bot permits somebody to do two issues: if they’ve an individual’s Fb consumer ID, they will discover that individual’s cellphone quantity, and if they’ve an individual’s cellphone quantity they will discover their Fb consumer ID. Although, in fact, really having access to the data you are in search of prices cash — unlocking a bit of knowledge, like a cellphone quantity or Fb ID, prices one credit score, which the individual behind the bot is promoting for $20. There’s additionally bulk pricing accessible, with 10,000 credit promoting for $5,000, in line with the Motherboard report.
The bot has been operating since at the least January 12, 2021, in line with screenshots posted by Gal, however the knowledge it offers entry to is from 2019. That’s comparatively outdated, however folks don’t change cellphone numbers that always. It’s particularly embarrassing for Fb because it traditionally collected cellphone numbers from folks together with customers who were turning on two-factor authentication.
For the time being it’s unknown if Motherboard or safety researchers have contacted Telegram to attempt to get the bot taken down, however hopefully it’s one thing that may be clamped down on quickly. That’s to not paint too rosy an image, although — the information remains to be on the market on the internet, and it’s resurfaced a few instances because it was initially scraped in 2019. I’m simply hoping that the simple entry will likely be lower off.
