Japanese anime and gaming giant admits data leak following ransomware attack

Kadokawa confirmed a ransomware attack attributed to the BlackSuit group (a Royal/Conti rebrand) that reportedly exfiltrated ~1.5 TB of data — including partner contracts and employee personal information from subsidiary Dwango — and led to temporary suspension of Niconico live services; attackers published a sample and threatened to release additional data, while Kadokawa is investigating the breach with external specialists and has not disclosed a ransom payment.
