Yjqs was created for the sole function to encrypt all popular file types. Rationally, as quickly as the encryption is effectively achieved, the users are not able to get access to them. Yjqs ransomware includes its own “.yjqs” to all the encrypted files. For instance, the file “price_list.xls”, when crypted by Yjqs, will be titled as “price_list.xls.yjqs”. As soon as the encryption is achieved, Yjqs puts its own unique text file (_readme.txt) into all the folders that store the encrypted files.
The message specified by document requesting for the random os really comparable to the alerts offered by other ransomware dangers belonging to the DJVU family. The warning basically shows that the files have been encrypted and the only service to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.
The technique to secure the files used by Yjqs is not entirely looked into. However, there is no doubt that each computer owner might be issued an unique decryption key, which is absolutely special. It is incredibly difficult to recover the information without the suitable key in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Yjqs infection 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 scoundrels who have launched the Yjqs infection into the internet. In order to get the key and restore the essential data, the users are told to connect with the scams through email or by telegram and to pay the ransom in the quantity of $980.
The message also states that individuals should get in touch with the Yjqs authors within 72 hours upon the minute of the data file encryption. The alert indicates that by doing so individuals will acquire a 50% discount, for that reason, the ransom quantity falls to $490.
