The big story: Facebook faces questions over data breach A data breach involving personal data (such as email addresses and phone numbers) of more than 500 million Facebook accounts came to light over the weekend thanks to a story in Business Insider. Although Facebook said the breach was related to a vulnerability that was “found and fixed” in August 2019, the Irish Data Protection Commission — Facebook’s lead data regulator in the European Union — suggested that it’s seeking the “full facts” in the matter. “The newly published dataset seems to comprise the original 2018 (pre-GDPR) dataset and combined with additional records, which may be from a later period,” said deputy commissioner Graham Doyle in a statement. “A significant number of the users are EU users. Much of the data appears to been data scraped some time ago from Facebook public profiles.”
