Facebook’s parent company, Meta, has been fined €17 million (~$18.6M) by the Irish Data Protection Commission (DPC) over a string of historical data breaches.

The security lapses in question, which appear to have affected up to 30M Facebook users, date back several years — and had been disclosed by Facebook to the Irish regulator in 2018.
