A Florida and an Ohio plaintiff have filed a class action against Warner Music Group Corp., the record label for artists such as Pitbull, Coldplay and the Rolling Stones, for allegedly failing to safeguard personally identifiable information and by not providing adequate notice to customers after a cybersecurity breach.

The lawsuit by named plaintiffs Levi Combs and Esteban Trujillo followed a company disclosure that between April 25 and Aug. 5, hackers accessed the customers’ personal data, such as names, billing addresses and payment card details. The breach remained undetected for three months.
