Personal information, including phone numbers, full names, locations, email addresses, birthdates, and other identifying information of 533 million Facebook users were posted on a low-level hacking forum.
According to Business Insider, the data breach affected Facebook users from 106 countries, and 32 million records were from United States-based users.
According to Alon Gal, the chief technology officer of the cybercrime intelligence firm Hudson Rock, even though the data leak is a couple of years old, it could still be potentially harmful. Hackers can use the information to engage in identity theft. Business Insider was able to review the information and tested the validity of some of the data.
In January, Gal came across the data when another hacker on the forum offered the information for a price. This weekend, the data set was listed on the hacking forum for free.
CNN reports that you can check to see if your information is part of the compromised data set by entering your email address on haveibeenpwned.com. The website is considering adding phone numbers since only a small fraction of emails were included in the breach.
