Facebook data leak

An unprotected server which hosted a Facebook database leaked millions of Facebook users’ phone numbers online. According to reports, the server wasn’t password-protected, allowing anyone to access it. The database contained more than 419 million records of Facebook users across the globe, including 133 million records of U.S. users, 18 million records of U.K. users, and more than 50 million records of Vietnamese users. The records contained unique Facebook IDs and the phone numbers linked to their accounts.

In April 2019, researchers also discovered a massive trove of Facebook user account information being exposed on Amazon cloud servers. The security team at UpGuard stated that they found two data breach incidents in different regions. Facebook also admitted to another data breach involving roughly 100 third-party app developers who had improper data access. This incident exposed around 146 GB of data that contained over 540 million records detailing comments, likes, reactions, account names, FB IDs, and other sensitive information.

The company said that an unauthorized third-party accessed its user data on May 4, 2019. DoorDash clarified that users who joined its services platform on or before April 5, 2018, were affected in the incident and the ones who joined after April 5, 2018, weren’t.
