The .onion Dharma ransomware aims to find all target files mentioned above so it can implement the AES encipher algorithm and render them completely unusable. This latest variant of Dharma is associated primarily with the .onion file extension and an email address that is left be the hackers as a way to contact them for the payment process. One of the emails associated with .onion ransomware is [email protected]. So all encrypted files may look corrupted and have malicious file extensions that follow the pattern:

.id-| victimID |.[[email protected]].onion

During the decryption process, the ransomware generates a decryption key, connects to its remote command and control server and delivers the key to the crooks. The whole infection process happens unnoticeably until its final stage. During its last stage, the ransomware drops an HTA, TXT, JPG or HTML file that contains a ransom message and payment instructions. The file is likely to be located on the desktop as well as in all folders that contain encrypted files. The .onion ransomware may also modify the default desktop wallpaper and replace it with the ransom note. As the previous .wallet variant, .onion Dharma ransom message instructs victims how to contact hackers at a given email in order to follow their further instructions and transfer Bitcoins to a given bitcoin address.
