What you need to know about the Facebook data leak

The news: The personal data of 533 million Facebook users in more than 106 countries was found to be freely available online last weekend. The data trove, uncovered by security researcher Alon Gal, includes phone numbers, email addresses, home towns, full names, and birth dates. Initially, Facebook claimed that the data leak was previously reported on in 2019 and that it had patched the vulnerability that caused it that August. But in fact, it appears that Facebook did not properly disclose the breach at the time. It only finally acknowledged it on Tuesday April 6 in a blog post by product management director Mike Clark.
