Remove Moka Ransomware (.moka File Infection)

Removal of Moka ransomware virus is a bit complicated. Therefore, we made a guide below to simplify the process. Execute the procedures in exact order to ensure complete removal of the ransom virus from infected computer.

Moka is a computer virus, which the name was derived from the file extension that it appends on every infected data. In this case, scene.jpg will become scene.jpg.moka after it was infected with the said virus. There are so many variants of this virus but Moka ransomware is the one currently active in attack campaign and it is spreading rapidly through several means prepared by the malware authors.

One of the favorable ways for Moka ransom virus to penetrate a computer is by attaching the malicious code to spam email messages. This spam email though has no specific target and recipient that would open the attached file is the unlucky receiver of Moka ransomware. Because attackers are mass mailing the virus to a large list of contact addresses, a fraction of them will become potential victims specially those that are careless email users.

Despite of having a successful widespread deployment using mass-mailing tactics, people behind Moka ransomware are also using alternative method to distribute the virus. Among the secondary distribution conduit are malicious advertisements, software piracy, and links from social media sites.

If Moka ransomware penetrates the computer in either ways, the outcome will be catastrophic for its victims. Since the malicious code is based from the STOP family, this new variant is expected to lock majority of files in the same manner where it remains unusable. Moka ransomware is using the same previous but effective encryption technique to hold infected files as hostage. This way, attackers are having all the leisure to demand money from victims as compensation to private key and decryption software that is vital to recover the entire .Moka files.

Following the file encryption process, the virus generates a ransom note (_readme.txt) file instructing victims to contact the malware authors and amount needed to proceed with file recovery. Below is an excerpt from the ransom note.

Ways to recover files encrypted by Moka Ransomware

Moka decryption tool called Decrypter_2 is provided by Emmanuel_ADC-Soft and is known effective in recovering .moka infected files if the malware uses Offline Key during the encryption process. You can download the tool from our Ransomware Decryption Tools archive. After downloading the tool, please execute these procedures:

1. As stated in the tool, entering incorrect key may result to permanent file damage. Therefore, it is important to Backup Your Files onto blank removable drive before proceeding with the decryption.

Warning: If you attach a writable USB Hard Drive or Flash Drive onto infected computer, the virus may also encrypt all clean files on that media. Therefore, Blank storage device is recommended if you haven’t removed the virus yet.

2. Double-click Decrypter_2.exe to run the tool. This process may prompt Windows OS for you permission. Just allow the program to run.

3. You need to input three items on the tool namely Private Key (download here), Personal ID (see the _readme.txt file on your computer), and File Name of the ransom note, which should remain as-is, shown in the image below.

4. To test and decrypt one .moka file, please click the Decrypt File button. The tool will automatically decrypt a single file without having to click on Start Button.

To decrypt several files, please click Decrypt Folder. The tool will start recovering files on selected folder and continue to search other locations and decrypt them as well.

Clicking on the Start button immediately will prompt the tool to thoroughly check all folders on the computer.

Alternative Solution:

If your PC is running on Windows Vista and Windows 7, there is a feature called ‘Previous Versions’. Although this function only works if restore point was saved prior to moka infection or if System Protection is enabled on the computer. Use Previous Versions to recover files without having to pay for the private key.
