Ransomware is a type of malicious software that prevents victims from using their files by encrypting them. Usually, users cannot decrypt their files without using right decryption key/tool. It is a part of Dharma ransomware family. This variant encrypts all types of files and renames them by adding cyber criminal’s email address, victim’s ID and by appending “.cum” extension to the end of filenames and makes totally useless.

Just after finishing encryption process, Cum displays a pop-up window and creates a text file named “info.txt” and dropped it on victim’s desktop as its ransom notes. The created file contains instructions on how to contact the attackers, pay for a decryption tool or other contact, payment information. According to the note, the only way of recovering the data is by purchasing the decryption key from the criminals behind the ransomware attack.

Moreover, users are warned not to rename encrypted files or try to decrypt them using third party software as it might leads into permanently damage files.
