A massive data set that includes the personal information of 533 million global Facebook users has been leaked and is widely circulating online. The data, which includes user phone numbers, email addresses, physical addresses, account creation dates, relationship status, and more, was being freely traded in hacker forums over the weekend. 

The scraped data was gleaned from Facebook users in more than 106 countries. The leak is believed to have originated courtesy of a 2020 vulnerability, first reported by Motherboard, that allowed users to exploit Facebook’s systems using an automated Telegram bot. Reddit posters and others have been quick to point out that if the number of people affected by this breach were a country, it would be the third most populous in the world, behind China and India.
