Profile of the Cloak Ransomware Group

Cloak emerged in August 2023 and has quickly gained notoriety for its aggressive cyber extortion tactics. The group primarily targets small to medium-sized businesses across Europe, employing a double extortion strategy. This involves encrypting victims' data and threatening to leak it unless a ransom is paid.
