Mtogas Virus Ransomware

Mtogas is a malicious software application working as common ransomware. Michael Gillespie, the well-known virus researcher, very first discovered this new name in the DJVU ransomware family.

Mtogas was developed for the sole function to encrypt all popular file types. Realistically, as soon as the encryption is effectively achieved, the users are unable to get access to them. Mtogas ransomware adds its own “.mtogas” to all the encrypted data. For example, the file “price_list.xls”, once modified by Mtogas, will be entitled as “price_list.xls.mtogas”. When the encryption is accomplished, Mtogas puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.

The alert mentioned by document requesting the random os extremely similar to the notifications offered by other ransomware threats coming from the DJVU family. The caution basically indicates that the files have 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 approach to secure the files utilized by Mtogas is not totally researched. Nevertheless, there is no doubt that each computer owner may be provided a special decryption key, which is definitely special. It is exceptionally tough to recover the information without the suitable key in place.

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

message from Mtogas virus

One more peculiarity of the Mtogas infection 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 introduced the Mtogas infection into the internet. In order to obtain the key and bring back the crucial data, the users are informed to get in touch with the scams via e-mail or by telegram and to pay the ransom in the quantity of $980.

The message also says that the people must contact the Mtogas authors within 72 hours upon the moment of the data file encryption. The alert shows that by doing so the people will get a 50% discount, therefore, the ransom quantity falls to $490.

No matter what the amount of the ransom is, we highly recommend 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 encryption, even when the amount of the ransom is received into their accounts. Thus, paying ransom often does not lead to a successful recovery. So, the users may simply lose their money for absolutely nothing.

Likewise, we advise you not to get in touch with the frauds as they advise. Do not move money into their wallets. There are no applications that might split the Mtogas ransomware or restore the information at no charge. For that reason, the only correct choice is to restore the data from possible backups (if readily available).
