By Neil Hodge2021-04-08T20:19:00+01:00 Last weekend, reports surfaced that the personal data of more than 533 million Facebook users had been made publicly available on a hacker forum. The social media firm responded the data had been stolen and made public from a reported data breach that took place in early 2018. Because the breach predated the General Data Protection Regulation (GDPR) coming into force, and because—according to Facebook—no new breach has occurred, the company believes it has no case to answer. Its lead European data supervisory authority, the Irish Data Protection Commission, however, has sent Facebook detailed questions to determine what happened given the tremendous amount of data involved, according to Deputy Commissioner Graham Doyle.
