.0000 Files Virus Encryption Process

The encryption of the .0000 files ransomware is conducted in the same way as other CryptoMix variants. The virus begins by having a pre-configured set of file extensions which it scans for in order to encrypt them. These file extensions belong ot the most often used file types, like videos, archives, documents, images and others, for example:


After detecting the files, the malware uses the AES encryption algorithm in order to encrypt the files. This process replaces the data from the original files with data from the encrypted file types. After doing this, the .0000 ransomware generates a unique AES decryption key. This key is assymetric and just like the XZZX ransomware variant of CryptoMix, the .0000 ransomware uses 11 RSA-1024 encrption keys to encrypt the AES assymetric key, used for the encryption of your files. This gives the .0000 ransomware the ability to work as an offline virus without even communicating with the cyber-criminals allowing their command and control server to be exposed.

After the encryption process of this CryptoMix ransomware variant has completed, the malware adds the .0000 file extension to the encrypted files and then completely renames them, so that you won’t be able to recognize which file is the most important to you. The files begin appearing like shown in the image below:
