Ljaz Virus Removal Guide (+Decrypt .ljaz files)

Ljaz – Ransomware

Ljaz is a malicious software application functioning as typical ransomware. Michael Gillespie, the widely known virus researcher, very first discovered this new name in the DJVU ransomware family.

Ljaz was created for the sole purpose 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. Ljaz virus includes its own “.ljaz” to all the encrypted files. For example, the file “price_list.xls”, when modified by Ljaz, will be entitled as “price_list.xls.ljaz”. As soon as the encryption is accomplished, Ljaz puts its own unique text file (_readme.txt) into all the folders that store the encrypted files.

The alert mentioned by text file requesting for the random os really comparable to the notices offered by other ransomware dangers coming from the DJVU family. The warning generally shows that the data has been secured and the only service to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.

The technique to secure the files used by Ljaz is not completely looked into. Nevertheless, there is no doubt that each computer system owner may be released a special decryption key, which is absolutely special. It is very tough to recover the data without the suitable type in location.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Ljaz infection is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the criminals who have released the Ljaz virus into the internet. In order to obtain the key and bring back the important data, the users are told to connect with the scams by means of email or by telegram and to pay the ransom in the amount of $980.

The message also says that individuals ought to get in touch with the Ljaz authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so individuals will get a 50% discount, for that reason, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we highly advise that you do not pay the ransom. There is no assurance that these online crooks will keep their guarantees, so they may not care at all what the victims feel about the encryption, even when the amount of the ransom is gotten into their accounts. Hence, paying ransom often does not result in an effective healing. So, the users might just lose their money for absolutely nothing.

There are no applications that might break the Ljaz ransomware or bring back the information at no charge. Therefore, the only proper choice is to restore the data from possible backups (if readily available).
