Yzaq – Ransomware
Yzaq is a destructive software functioning as typical ransomware. Michael Gillespie, the popular virus researcher, very first found this new name in the DJVU ransomware family.
Yzaq was developed for the sole purpose to encrypt all popular file types. Logically, as quickly as the file encryption is successfully accomplished, the users are unable to get access to them. Yzaq virus adds its own “.yzaq” to all the encrypted data. For instance, the file “price_list.xls”, as soon as modified by Yzaq, will be entitled as “price_list.xls.yzaq”. Once the encryption is achieved, Yzaq puts its own unique text document (_readme.txt) into all the folders that save the encrypted files.
The message stated by document requesting the random os really similar to the notices offered by other ransomware hazards belonging to the DJVU family. The caution generally indicates that the information has been secured and the only service to get access to it is to use a special standalone key. Regretfully, this statement is absolutely real.
The technique to secure the files used by Yzaq is not entirely looked into. However, there is no doubt that each computer system owner might be released an unique decryption key, which is definitely distinct. It is incredibly tough to recuperate the information without the appropriate key in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Yzaq infection is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the crooks who have actually introduced the Yzaq infection into the world wide web. In order to obtain the key and restore the crucial data, the users are informed to get in touch with the frauds by means of email or by telegram and to pay the ransom in the amount of $980.
The message also states that individuals should contact the Yzaq authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so individuals will acquire a 50% discount rate, therefore, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we highly recommend that you do not pay the ransom. There is no guarantee that these online crooks will keep their guarantees, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts. Hence, paying ransom typically does not result in an effective recovery. So, the users might just lose their money for nothing.
Similarly, we urge you not to call the frauds as they advise. Do not transfer cash into their wallets. There are no applications that could split the Yzaq virus or restore the information for free. For that reason, the only right choice is to restore the information from possible backups (if offered).
