The operators behind the RobbinHood ransomware have changed their language in the ransom note, at least in one variant of the malware, to take from victims all hope of decrypting the files for free and to make them pay for the recovery.

Boastful and arrogant in their message, the cybercriminals point to past incidents involving their ransomware, which ended with victims paying much more than the ransom demand.

They emphasize the fact that there is no decryption tool available for the encryption scheme implemented in RobbinHood ransomware, so it is “impossible to recover” the files without the private key and their unlocking software.
