Facebook data breach exposes phone numbers of 533 million users

In early 2020, Facebook had a vulnerability that allowed hackers to access the phone numbers of 533 million users. The data was leaked online in January 2021.

The leak included the phone numbers, Facebook IDs, full names, locations, birthdates, and bios of users from all over the world. It is estimated that 2,838 Cambodian users were affected by the breach.

Facebook has since fixed the vulnerability, but the data is still available online. Security experts recommend that users change their passwords and enable two-factor authentication to protect their accounts.

What Facebook is doing to protect users

Facebook has said that it is working to notify users who were affected by the breach. The company is also taking steps to improve the security of its platform.
