Article created to help wipe out the DarkLocker ransomware virus, also known as Monument ransomware and assist in restoring files without paying ransom.
Ransomware infection believed to be an evolved modification of the JigSaw ransomware variant, has been detected. Besides showing a lockscreen message, the DarkLocker ransomware also encrypts the files on the computers infected by it. After the files are encrypted, the DarkLocker ransomware demands the payoff of approximately 0,15-0.20 BTC for the restoring of the encrypted files. In case you have become a victim of this cyber-threat, reccomendations are to focus on reading this article thoroughly.

DarkLocker Ransomware – How Does It Spread
For this ransomware infection to actually reach computers of unsuspecting users, the creators of the virus have also engineered a plan to spread it. One scenario of spreading the ransomware is by conducting a massive spam campaign of e-mail messages sent to many users on a global scale. To do this, the cyber-criminals may have a pre-configured e-mail list of legitimate e-mail addresses. To obtain such lists, they may purchase it on the black market by someone who collects personal information by stealing it or breaking privacy policy of shady websites.
Then, these e-mails may be embedded in a spam bot which in it’s turn sends spam messages with malicious e-mail attachments, like the example below:
Once the attachment is opened, infection by DarkLocker is inevitable.
But this may not be the only way of infecting with this virus. The DarkLocker malware may spread via fake updates, programs, patches and other “software” uploaded online as well.
DarkLocker Ransomware – Activity
Once the user becomes infected, the virus may situate it’s malicious files on the following Windows folders of great importance:
- %AppData%
- %Roaming%
- %Local%
- %LocalRow%
- %SystemDrive%
- %Startup%
- %Windows%
Among the malicious files may be different types of exectuables as well as support modules, but the main two identified are named as the following:
- can.exe
- Winlk.exe
After this infection drops it’s files, it may initiate modifications by adding value strings with data in the Windows Registry Editor. The predominantly targeted Windows Registry keys are the following:
→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
In addition to this, the DarkLocker ransomware may also delete backups, system restore points and shadow volume copies of Windows. It may also shut down critical system security processes to ensure uninterrupted file encryption
DarkLocker Ransomware – Encryption Process
For the file encryption of this virus, one or more than one encryption modes can be used to render the files no longer openable. This is achievable by combining the encryption mode with the cipher. The DarkLocker virus may be pre-configured to encrypt only a portion of the files, hence the larger the file, the more size will be encrypted. This is done to ensure a faster encryption process. For the infection, DarkLocker may target certain files of bigger importance than the average file types. Such files may be:
- Documents.
- Images.
- Audio files.
- Videos.
- Database files.
- Other files associated with often used software.
In addition to performing this, the DarkLocker virus may also be careful to avoid encrypting files in different system folders, that may cause Windows to misbehave and even crash.
After the encryption process is compete. The ransomware has been reported by researcher Amigo A to display the following ransom note type of file, extorting victims to pay ransom:
Remove DarkLocker Ransomware and Restore Files Encrypted by It
Before beginning to remove this virus, recommendations are to focus on saving the files encrypted by it on another drive, preferably external.
Then, we advise you to follow the following removal instructions to help you remove DarkLocker by isolating it first. In case you feel unsure that you will remove all objects created by this virus manually, recommendations are to focus on performing the removal process automatically by downloading an advanced anti-malware program. It will detect and remove DarkLocker files automatically and protect the system against any future intrusions too.
After having removed DarkLocker virus, reccomendations are to focus on restoring your files using some alternative methods. We have mentioned several of those in step “2. Restore files encrypted by DarkLocker” below. They are designed to enable you to restore at least some of the files, until a decryptor is released for free download. In the meantime you can check this article, as we will update it if there is any development with this virus.

Step 2: Uninstall DarkLocker and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision.

The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by DarkLocker on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by DarkLocker there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove DarkLocker
Step 5: Try to Restore Files Encrypted by DarkLocker.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
