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 line with a report by Motherboard. The safety researcher who discovered this vulnerability, Alon Gal, says that the one that 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 seek out any helpful knowledge. And there typically 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 simply give another person all that precious knowledge. Making a Telegram bot, nonetheless, solves each of those points.
Few days in the past a person created a Telegram bot permitting customers to question the database for a low price, enabling folks to seek 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 person ID, they’ll discover that particular person’s cellphone quantity, and if they’ve an individual’s cellphone quantity they’ll discover their Fb person ID. Although, in fact, really 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 line with the Motherboard report.
The bot has been operating since at the very least January 12, 2021, in line with screenshots posted by Gal, however the knowledge it supplies entry to is from 2019. That’s comparatively outdated, however folks don’t change cellphone numbers that usually. 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 meanwhile 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 internet, and it’s resurfaced a few instances because it was initially scraped in 2019. I’m simply hoping that the simple entry will probably be minimize off.
