Moqs – General Info

Moqs is a malicious software working as typical ransomware. Michael Gillespie, the well-known virus researcher, very first found this new name in the DJVU ransomware family.

Moqs was developed for the sole purpose to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively achieved, the users are unable to get access to them. Moqs virus includes its own “.moqs” to all the encrypted files. For instance, the file “price_list.xls”, when crypted by Moqs, will be entitled as “price_list.xls.moqs”. When the encryption is accomplished, Moqs puts its own special text file (_readme.txt) into all the folders that store the encrypted files.

The alert mentioned by _readme.txt asking for the random os really similar to the notices given by other ransomware threats belonging to the DJVU family. The caution basically indicates that the data has been encrypted and the only service to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.

The method to encrypt the files utilized by Moqs is not completely researched. Nevertheless, there is no doubt that each computer owner may be issued a special decryption key, which is definitely special. It is very difficult to recuperate the information without the proper key in location.

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

One more peculiarity of the Moqs infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the criminals who have launched the Moqs ransomware into the world wide web. In order to get the key and bring back the essential information, the users are informed to get in touch with the frauds through email or by telegram and to pay the ransom in the amount of $980.

The message also says that the people ought to get in touch with the Moqs authors within 72 hours upon the moment of the information encryption. The alert suggests that by doing so individuals will acquire a 50% discount, therefore, the ransom amount drops down to $490.

No matter what the amount of the ransom is, we strongly recommend that you do not pay the ransom. There is no assurance that these online criminals will keep their pledges, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. Thus, paying ransom frequently does not result in a successful recovery. So, the users might just lose their money for absolutely nothing.

There are no applications that might split the Moqs ransomware or restore the information for free. Therefore, the only right choice is to restore the information from possible backups (if available).
