Somebody has gotten their fingers on a database stuffed with Fb customers’ cellphone numbers, and is now promoting that knowledge utilizing a Telegram bot, in accordance 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 ability is required to seek out any helpful knowledge. And there usually must be an interplay between the particular person with the database and the particular person making an attempt to get info out of it, because the database’s “proprietor” isn’t going to only give another person all that worthwhile knowledge. Making a Telegram bot, nevertheless, 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 seek out the cellphone numbers linked to a really giant 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 particular person’s cellphone quantity, and if they’ve an individual’s cellphone quantity they will discover their Fb consumer ID. Although, in fact, truly having access to the data you are in search of prices cash — unlocking a chunk of data, like a cellphone quantity or Fb ID, prices one credit score, which the particular person behind the bot is promoting for $20. There’s additionally bulk pricing out there, with 10,000 credit promoting for $5,000, in accordance with the Motherboard report.
The bot has been working since at the very least January 12, 2021, in accordance with screenshots posted by Gal, however the knowledge it gives entry to is from 2019. That’s comparatively previous, 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 have been turning on two-factor authentication.
In the intervening time 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 info continues to be on the market on the net, and it’s resurfaced a few occasions because it was initially scraped in 2019. I’m simply hoping that the straightforward entry will probably be minimize off.
