The Proton ransomware family has seen numerous iterations since its emergence in March 2023. The latest variant, Zola, includes advanced features such as privilege escalation measures, a disk overwriting function, and a keyboard language-based kill switch, making it a sophisticated threat.
The Acronis Threat Research Unit recently conducted an in-depth analysis of Zola, highlighting the ransomware family’s ongoing evolution and adaptation.

Proton Ransomware: A Timeline of Evolution
Since its initial appearance, the Proton ransomware family has gone through several transformations. The latest Zola variant was discovered in May 2023 and is part of a pattern of constant code tweaks and rebranding efforts. This evolution shows the persistence and adaptability of its developers.
Key Features of Zola Variant
Kill Switch and Admin Privilege Checks
The Zola variant introduces a kill switch that checks for a Persian keyboard layout, halting its processes if detected. This feature might suggest the geographic origin of the ransomware, though further evidence is lacking. If the kill switch is not triggered, Zola proceeds to check for administrative privileges, repeatedly prompting the user to run the executable as an administrator if initial attempts fail.
Similarities to Previous Variants
Zola shares several characteristics with its predecessors, such as the creation of a mutex to prevent concurrent executions. The ransomware also uses common hacking tools like Mimikatz and ProcessHacker to disable security measures and enhance its capabilities.
Attack Execution and Encryption Process
Once administrative privileges are secured, Zola prepares for encryption by generating a unique victim ID and key information, emptying the Recycle Bin, modifying boot configurations, and deleting shadow copies to thwart recovery efforts. The malware then targets 137 processes and 79 services, including various security applications, to ensure successful encryption.
Encryption Scheme
Zola employs the ChaCha20 encryption scheme, a change introduced in September 2023, while the ransom note misleadingly claims the use of AES and ECC encryption. This deceptive tactic adds another layer of complexity to the ransomware’s operations.
Disk Overwriting and Ransom Note Deployment
A notable feature of Zola is its ability to overwrite disk space by continuously writing uninitialized data, complicating digital forensics and data recovery.
The ransomware runs multiple encryption threads, targeting network-attached drives and dropping ransom notes in each encrypted folder. Additionally, it changes the desktop wallpaper to instruct victims on how to contact the threat actors.
Notable Differences from PrOToN/Xorist Ransomware
Despite sharing a similar name, the Proton ransomware family should not be confused with PrOToN, a variant of the Xorist ransomware family. PrOToN, which emerged around August 2023, features distinct differences in encrypted file extensions and ransom note formats. Notably, PrOToN displays an “Error” pop-up window with the ransom note text, a feature absent in Zola and other Proton variants.
In conclusion, the Zola variant of Proton ransomware highlights the ongoing evolution and sophistication of ransomware threats. With advanced features like privilege escalation, disk overwriting, and deceptive encryption claims, Zola represents a significant threat to cybersecurity.
Zola Ransomware Removal
To defend against the latest variant of Proton ransomware, adopting proactive and comprehensive security measures is indispensable. Implementing strict security protocols and staying informed about the ransomware’s operational methods can significantly diminish the likelihood of an attack.
Key strategies include updating and patching systems regularly to fix vulnerabilities, employing strong and unique passwords, and educating users about the dangers of phishing emails and malicious attachments. Moreover, adopting a layered security approach, which includes using antivirus software, firewalls, and intrusion detection systems, can provide a robust defense against potential attacks.
Using SpyHunter for Detecting and Removing Proton Ransomware

Step 2: Uninstall Zola virus 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 Zola virus 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 Zola virus 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 Zola virus
Step 5: Try to Restore Files Encrypted by Zola virus.
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 Zola virus 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.
