What Is Zen Ransomware?
Zen ransomware is a variant of the Dharma ransomware family, a well-known and widely distributed strain that has been active since around 2016. Like other Dharma variants, Zen is used by cybercriminals to encrypt a victim’s files and demand a ransom in exchange for a decryption tool. It inherits the core characteristics of Dharma but uses specific identifiers to mark its presence.
Zen Ransomware Summary
| Name | Zen Ransomware |
| File Extension | .V |
| Type | Ransomware, Cryptovirus |
| Short Description | The ransomware encrypts files on your computer system and demands a ransom to be paid to allegedly recover them. |
| Symptoms | The ransomware will encrypt your files by appending the .V extension to them, along with a unique identification number placing the new .PGP extension as a secondary. |
| Distribution Method | Remote desktop protocol (RDP) brute-force attacks to gain unauthorized access to victim systems, followed by manual deployment of the ransomware payload. |

How Does Zen Ransomware Spread?
Zen ransomware, like other variants of the Dharma ransomware family, is primarily distributed through compromised Remote Desktop Protocol (RDP) services. What does this mean?
Cybercriminals scan the internet for systems with exposed or poorly secured RDP ports, then use brute-force attacks or stolen credentials to gain unauthorized access.
Once inside the network, attackers manually deploy the Zen ransomware payload to maximize damage. In some cases, Zen may also be spread via malicious email attachments, phishing links, or bundled with pirated software and fake installers.
Unlike automated malware campaigns, Zen infections are often part of targeted attacks, where the threat actors take time to identify valuable files and disable system protections such as backups and shadow copies before launching the encryption process. This method of manual distribution allows them to demand higher ransom payments and increases the chances of successful extortion.
Zen Ransomware’s Ransom Note
This is what the ransom note states:
All your files have been encrypted!
Don’t worry, you can return all your files!
If you want to restore them, write to the mail: zen_crypt@tuta.io YOUR ID –
If you have not answered by mail within 12 hours, write to us by another mail:zen_crypt@cyberfear.comFree decryption as guarantee
Before paying you can send us up to 3 files for free decryption. The total size of files must be less than 3Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)How to obtain Bitcoins

Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.
Zen Ransomware Encryption
Zen ransomware uses a hybrid encryption scheme, combining both AES and RSA algorithms to lock victims’ files. During the encryption process, Zen generates a unique AES key for each file, which is then used to encrypt the file content. To prevent the victim from accessing these AES keys, Zen encrypts them using an RSA public key hardcoded into the ransomware. As a result, decryption requires the corresponding RSA private key, which is only available to the attackers. This dual-layer encryption makes brute-forcing the decryption key virtually impossible without access to the attacker’s private RSA key. A
Also, encrypted files are renamed with a specific extension format, typically ending in .zen along with a unique victim ID and the attacker’s contact email: .filename.id-[unique_ID].[zen777@keemail.me].zen.
Remove Zen Ransomware
Removing Zen ransomware from an infected system requires careful action to prevent further damage or reinfection.
The first step is to disconnect the affected device from the internet and any local networks to stop the ransomware from spreading to other systems.
Next, run a full system scan using reputable antivirus or anti-malware software to detect and remove the ransomware payload and any associated malicious files. It’s important to note that while removal tools can eliminate the ransomware itself, they will not decrypt the encrypted files. Manual removal is not recommended unless performed by IT professionals, as Dharma-based variants like Zen often hide components deep within the system and may tamper with system settings or disable recovery features.
After removal, users should check for backups stored offline or in the cloud to restore their data. If no backups exist, files may remain permanently locked unless a decryption tool becomes available in the future, though none currently exists for Zen.

Step 2: Uninstall Zen Ransomware 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. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. 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 Zen Ransomware 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 Zen Ransomware 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 Zen Ransomware
Step 5: Try to Restore Files Encrypted by Zen Ransomware.
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:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and Zen Ransomware aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
