Massive data leak conducted by HelloKitty ransomware amid rebrand

Ransomware operation HelloKitty has coincided its rebranding to HelloGookie with the publication of internal Cisco network data exfiltrated from a 2022 attack, exfiltrated source code for several CD Projekt Red games from a 2021 attack, and four private decryption keys for other intrusions that involved an older iteration of its ransomware encryptor, according to BleepingComputer.
