Security News > 2022 > November > Ukraine says Russian hacktivists use new Somnia ransomware
Russian hacktivists have infected multiple organizations in Ukraine with a new ransomware strain called 'Somnia,' encrypting their systems and causing operational problems.
The group previously disclosed creating the Somnia ransomware on Telegram and even posted evidence of attacks against tank producers in Ukraine.
Until today, Ukraine has not confirmed any successful encryption attacks by the hacking group.
The agency also notes that the latest samples of the Somnia ransomware strain used in these attacks rely on the AES algorithm, whereas Somnia initially used the symmetric 3DES. The file types targeted by Somnia ransomware are shown below, including documents, images, databases, archives, video files, and more, reflecting the destruction this strain aims to cause.

Somnia does not request the victims to pay a ransom in exchange for a working decryptor, as its operators are more interested in disrupting the target's operations than generating revenue.
