International: Regulators issue statements on Facebook security breach affecting 533M individuals

The Irish Data Protection Commission ('DPC') issued, on 6 April 2021, a statement on recent reports that personal information from Facebook, Inc. had been made publicly availably. In particular, the statement highlights that this published dataset appears to comprise a dataset previously scraped from Facebook in 2018, which was not notified then, since it had occurred before the General Data Protection Regulation (Regulation (EU) 2016/679) ('GDPR') came into force, together with some additional records which might have been scraped at a later unidentified period.

Furthermore, the statement notes that the DPC and Facebook are currently investigating the matter, with Facebook providing that, since the data appears to have been collated by third parties and potentially stems from multiple sources, extensive investigation is required to confidently establish its provenance. Lastly, the statement outlines the risks arising from this incident, including users being spammed for marketing purposes or unauthorised access to personal data by third parties.

Separately, Facebook issued its own statement addressing recent reports, confirming that only a limited set of information had been obtained, which did not include financial information, health information, or passwords, and that it had taken measures in 2019 to address such vulnerabilities.
