Moka ransomware removal instructions
What is Moka?
Moka is a part of the Djvu ransomware family and was discovered by Michael Gillespie. Like most programs of this type, Moka encrypts files to prevent access. To regain access, victims must pay ransoms to cyber criminals (i.e., purchase a decryption tool). Moka renames all encrypted files by changing extensions to ".moka". For example, "1.jpg" becomes "1.jpg.moka". It also creates a ransom message within a text file called "_readme.txt".
To purchase a decryption tool and key, victims are encouraged to contact Moka developers via the firstname.lastname@example.org or email@example.com email address. They are permitted to attach one encrypted file, which cyber criminals offer to decrypt free of charge. These decryption tools cost $980, however, victims can purchase them for $490 if they contact Moka developers within 72 hours of encryption. Like most ransomware-type programs, Moka encrypts files with a strong encryption algorithm. Therefore, it is impossible to decrypt files without tools held only by the cyber criminals who designed Moka. Note that cyber criminals cannot be trusted - they often send no decryption tools even if their demands are met. In most cases, the only way to recover files free of charge (without having to contact and pay cyber criminals) is to restore them from a backup created prior to infection.

Moka is very similar to many other programs of this type, such as Kokoklock, .cmd, and Peta. In most cases, these programs encrypt data using strong cryptographic algorithms (symmetric or asymmetric) and create or display ransom messages. Typically, the main differences are size of ransom and algorithm that was used to lock the victim's data. Encrypted files cannot be decrypted without the tools held only by the ransomware developers, unless the program is not complete (contains bugs, flaws, and so on). In summary, the only way to recover files is to use a data backup. Therefore, maintain backups and store them on a remote server (such as Cloud) or unplugged storage device.

|Symptoms||Cannot open files stored on your computer, previously functional files now have a different extension (for example, my.docx.locked). A ransom demand message is displayed on your desktop. Cyber criminals demand payment of a ransom (usually in bitcoins) to unlock your files.|
|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads, unofficial activation and updating tools.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password-stealing trojans and malware infections can be installed together with a ransomware infection.|
To eliminate malware infections our security researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections
Ignore irrelevant emails that include various attachments or links and are received from unknown, suspicious addresses. These are often disguised as official and important, however, they should not be trusted or files attached to them, opened. Do not download or install software using third party downloaders/installers, unofficial websites, or other tools/sources of this kind. The safest way to download files and programs is to use official websites and direct download links. Installed software should be updated properly using tools or implemented functions designed by official software developers. If an installed program is not free, it should be activated properly. Various 'cracking' tools often infect systems with malware and are illegal to use. Scan the operating system for viruses regularly using reputable anti-virus or anti-spyware software. If your computer is already infected with Moka, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Moka ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Moka ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Moka are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Moka ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
