The message stated by document asking for the random os extremely similar to the alerts offered by other ransomware dangers belonging to the DJVU family. The caution essentially indicates that the files have been secured and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is definitely true.
The technique to secure the files utilized by Lssr is not totally investigated. However, there is no doubt that each computer system owner may be issued a special decryption key, which is absolutely special. It is very hard to recuperate the data without the appropriate key in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Lssr virus is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the criminals who have launched the Lssr virus into the web. In order to obtain the key and bring back the crucial data, the users are informed to connect with the frauds via email or by telegram and to pay the ransom in the amount of $980.
