A security research found a huge file on the “dark web” containing over 533 million users from a prior hacking attack in 2019

The Personal Data of More Than 533M Facebook Users Has Been Posted Online | PCMag


The personal data of more than 533 million users from 106 countries has been leaked and published online. That includes Facebook IDs, full names, locations, phone numbers, birthdates, and email addresses of more than 32 million people in the US. Business Insider reviewed and verified a sample of the leaked records, which Facebook claims were scraped “due to a vulnerability” that was patched in 2019.

Alon Gal, CTO of cybercrime intelligence firm Hudson Rock, spotted the disclosure on Saturday, explaining, “A database of that size containing the private information such as phone numbers of a lot of Facebook’s users would certainly lead to bad actors taking advantage of the data to perform social engineering attacks [or] hacking attempts.”   There’s not much Facebook can do in terms of security to help affected users, Gal explained, aside from warning folks to keep an eye out for phishing schemes or fraudulent activity.
