Over the weekend, cybersecurity experts revealed that about half a billion Facebook users’ personal information was breached — a treasure trove of data the includes full names, birthdays, phone numbers and their location.

Facebook said that massive leak stems from an issue in 2019, which has since been fixed. Still, there’s no clawing back that data. More than 30 million accounts in the United States were affected and the company isn’t making it easy to find out if your data was included in the breach.
