Moka Virus Removal Guide (+Decrypt .moka files)

Moka Virus Ransomware

Moka is a destructive software working as common ransomware. Michael Gillespie, the well-known virus researcher, first found this new name in the DJVU ransomware family.

Moka was developed for the sole function to encrypt all popular file types. Realistically, as quickly as the encryption is successfully achieved, the users are not able to get access to them. Moka virus adds its own “.moka” to all the encrypted files. For example, the file “price_list.xls”, when crypted by Moka, will be entitled as “price_list.xls.moka”. As soon as the encryption is achieved, Moka puts its own special text document (_readme.txt) into all the folders that save the encrypted files.

The alert specified by document requesting for the random os very comparable to the alerts provided by other ransomware threats coming from the DJVU family. The caution generally shows that the files have been encrypted and the only service to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely real.

The approach to encrypt the files utilized by Moka is not completely investigated. However, there is no doubt that each computer system owner might be released a special decryption key, which is definitely distinct. It is exceptionally difficult to recuperate the data without the suitable type in location.

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

message from Moka virus

One more peculiarity of the Moka virus is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the total control by the criminals who have actually introduced the Moka infection into the web. In order to get the key and restore the crucial information, the users are informed to get in touch with the frauds through e-mail or by telegram and to pay the ransom in the amount of $980.

The message likewise says that the people should contact the Moka authors within 72 hours upon the minute of the information file encryption. The alert suggests that by doing so the people will obtain a 50% discount, therefore, the ransom amount falls to $490.

No matter what the amount of the ransom is, we highly advise that you do not pay the ransom. There is no warranty that these online criminals will keep their pledges, 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. For this reason, paying ransom typically does not result in a successful healing. So, the users may merely lose their money for absolutely nothing.

Similarly, we advise you not to call the scams as they instruct. Do not transfer money into their wallets. There are no applications that might crack the Moka virus or bring back the data for free. Therefore, the only appropriate choice is to bring back the data from possible backups (if available).
