The working process of ransomware is fairly simple to understand. The ransomware starts its work by encrypting the files that are present on the compromised server. After this, the ransomware adds .DEMON extension to the filenames that have been encrypted by it. Moreover, it also adds a ransom note into the server which is usually named ReadMe.txt or decrypt_file.txt.

This ransom note is added to demand the amount pleased by the attacker as a payment for the decryption key. The attackers promise to hand over the decryption key to victims with which they can retrieve all their data, once the payment is made. However, it is not a very wise idea to trust the said attackers and in turn meet their demands or pay the amounts that they have asked for. This is because, most of the time, even after the demands are met, users do not receive the decryption as promised.
