533 Million Facebook Users' Personal Data Hacked

The leaked data includes FB users' phone numbers, full names, email addresses, locations, and biographical information.

According to a report from Business Insider the personal data of more than 500 million Facebook users was posted online, on Saturday, in a low-level hacking forum. This data includes FB users' phone numbers, full names, email address, location, and biographical information; from 106 countries.

Insider said that it reviewed a sample dataset of the leaked data and verified several records by matching known FB users' phone numbers with the IDs listed in the data set. According to a Facebook spokesperson, the data was scraped because of a vulnerability that the company patched in 2019. Approx 32 million users in the leaked data are from US, 11 million from UK, and 6 million from India. 

CTO of cybercrime intelligence firm Hudson Rock, Alon Gal, who first discovered the full trough of leaked data online on Saturday said that this data could provide valuable information to hackers and cybercriminals who make use of people's personal information to impersonate them or scam them into handing over login credentials.


All 533,000,000 Facebook records were just leaked for free.

This means that if you have a Facebook account, it is extremely likely the phone number used for the account was leaked.

I have yet to see Facebook acknowledging this absolute negligence of your data. https://t.co/ysGCPZm5U3 pic.twitter.com/nM0Fu4GDY8

Gal first spotted the leaked data in January when a member of the same hacking forum advertised an automated bot that could render phone numbers of hundreds of millions of FB users in exchange for a price.

According to Gal there's not much FB can do to help its users affected by the breach as their data is already out in the open. But the company could notify users(affected) so they could remain alert for possible phishing schemes or fraud using their personal data.
