While we addressed the issue identified in 2019, it’s always good for everyone to make sure that their settings align with what they want to be sharing publicly. While we can’t always prevent data sets like these from recirculating or new ones from appearing, we have a dedicated team focused on this work. We’re focused on protecting people’s data by working to get this data set taken down and will continue to aggressively go after malicious actors who misuse our tools wherever possible. We have teams across the company working to detect and stop these behaviors. Scraping data using features meant to help people violates our terms.

When we became aware of how malicious actors were using this feature in 2019, we made changes to the contact importer. This feature was designed to help people easily find their friends to connect with on our services using their contact lists. We believe the data in question was scraped from people’s Facebook profiles by malicious actors using our contact importer prior to September 2019. regarding a security breach (the Breach) that affected.

It is important to understand that malicious actors obtained this data not through hacking our systems but by scraping it from our platform prior to September 2019. We have teams dedicated to addressing these kinds of issues and understand the impact they can have on the people who use our services. Now the data set has been posted on the hacking forum for free, making it available to anyone with rudimentary data skills.On April 3, Business Insider published a story saying that information from more than 530 million Facebook users had been made publicly available in an unsecured database. Motherboard reported on that bot's existence at the time and verified that the data was legitimate.
Gal discovered the leaked data in January when a user in the same hacking forum advertised an automated bot that could provide phone numbers for hundreds of millions of Facebook users for a price. "A database of that size containing the private information such as phone numbers of a lot of Facebook's users would certainly lead to bad actors taking advantage of the data to perform social-engineering attacks hacking attempts," Gal told Insider.
