What is Deman?

Deman is a malicious program belonging to the Everbe ransomware family. This malware operates by encrypting the data of infected systems so that ransom demands can be made for decryption. During the encryption process, the filename extensions of all affected files have "deman" added to them.

For example, a file originally named something like "1.jpg" would appear as "1.jpgdeman" following encryption. After this process is complete, a text file ("!=How_to_decrypt_files=!.txt") is created on the desktop.

What is qlopx.xyz?
