Gatq – Ransomware

Gatq is a malicious software functioning as common ransomware. Michael Gillespie, the popular malware researcher, very first discovered this new name in the DJVU ransomware family.

Gatq was created for the sole purpose to encrypt all popular file types. Rationally, as soon as the encryption is effectively achieved, the users are unable to get access to them. Gatq virus includes its own “.gatq” to all the encrypted data. For instance, the file “price_list.xls”, when crypted by Gatq, will be entitled as “price_list.xls.gatq”. As soon as the encryption is accomplished, Gatq puts its own distinct text document (_readme.txt) into all the folders that keep the encrypted files.

The message specified by document requesting the random os very similar to the notifications offered by other ransomware hazards belonging to the DJVU family. The caution generally shows that the information has been secured and the only solution to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely true.

The method to secure the files used by Gatq is not completely looked into. Nevertheless, there is no doubt that each computer owner might be issued an unique decryption key, which is absolutely special. It is extremely tough to recuperate the data without the proper key in place.

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

One more peculiarity of the Gatq ransomware is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the total control by the scoundrels who have released the Gatq infection into the web. In order to acquire the key and restore the crucial data, the users are told to get in touch with the frauds by means of e-mail or by telegram and to pay the ransom in the quantity of $980.

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

No matter what the amount of the ransom is, we strongly encourage that you do not pay the ransom. There is no warranty that these online crooks will keep their promises, so they may 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 typically does not result in an effective recovery. So, the users may just lose their money for absolutely nothing.

There are no applications that might crack the Gatq virus or restore the information at no charge. Therefore, the only right decision is to restore the data from possible backups (if offered).
