Babuk | Babuk Ransomware is a sophisticated ransomware compiled for several platforms. Windows and ARM for Linux are the most used compiled versions, but ESX and a 32bit old PE executable were observed over time. as well It uses an Elliptic Curve Algorithm (Montgomery Algorithm) to build the encryption keys. | No Attribution |

STOP, Djvu | STOP Djvu Ransomware it is a ransomware which encrypts user data through AES-256 and adds one of the dozen available extensions as marker to the encrypted file's name. It is not used to encrypt the entire file but only the first 5 MB. In its original version it was able to run offline and, in that case, it used a hard-coded key which could be extracted to decrypt files. | No Attribution |
