Irish Data Protection Commission has launched an investigation into a data leak in which the personal details of approximately 533 million Facebook users (worldwide) were published online.
Facebook had earlier claimed that the data was old and from a previously reported leak in 2019.
The Data Protection Commission (DPC) in a statement said the investigation was “an own-volition inquiry pursuant to section 110 of the Data Protection Act 2018 in relation to multiple international media reports, which highlighted that a collated dataset of Facebook user personal data had been made available on the internet.”
The DPC said it has engaged with Facebook Ireland in relation to this reported issue, raising queries in relation to General Data Protection Regulation (GDPR) compliance to which the tech giant has responded.
Facebook in a statement, said, it was “co-operating fully,” adding that the inquiry “relates to features that make it easier for people to find and connect with friends on our services.”
The tech giant added, “These features are common to many apps and we look forward to explaining them and the protections we have put in place.”
Firms found to be in breach of GDPR face fines of up to 4% of their annual global turnover.
