The message mentioned by text file requesting the random os really similar to the notifications provided by other ransomware risks coming from the DJVU family. The warning essentially indicates that the information has been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely real.
The approach to secure the files used by Qeza is not completely looked into. Nevertheless, there is no doubt that each computer owner might be issued a special decryption key, which is definitely distinct. It is very tough to recuperate the data without the proper type in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Qeza virus is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the criminals who have actually released the Qeza ransomware into the internet. In order to obtain the key and bring back the essential data, the users are told to connect with the frauds by means of e-mail or by telegram and to pay the ransom in the quantity of $980.
