What Is Epsilon Red Ransomware?
Epsilon Red is a new ransomware detected in the wild, in attacks against various organizations. The ransomware uses the .epsilonred file extension.
Security researchers from Sophos recently reported a new ransomware threat, coded in the Go language. The ransomware, called Epsilon Red, was delivered as the final executable payload in “a hand-controlled attack” against US-based company in the hospitality industry. According to the analysis, all early-stage components of the attack were PowerShell scripts.
Evidently, the cryptocurrency address that belongs to the attackers shows that at least one of the victims paid a ransom, in the amount of 4.29 Bitcoin, equaling to approximately $210,000.
It is noteworthy that the ransom note dropped by the Epsilon Red ransomware is similar to REvil ransomware, with “a few minor grammatical corrections.” However, the researchers found no other resemblances between the two ransomware viruses.
In terms of the attack against the U.S. hospitality company, it seems that the attackers breached a Microsoft Exchange server as an initial entry point. However, it is not known whether they used the ProxyLogon exploit or some other vulnerability. Once they breached inside that vulnerable machine, the attackers used WMI to install other programs onto other machines inside the network, reachable from the initial Exchange server.
Where does the name Epsilon Red come from? The name is a reference to pop culture, as Epsilon Red is a character from the X-Men universe. He was a soldier most likely of Russian origin.

Epsilon Ransomware Technical Overview
The ransomware is called RED.exe, a 64-bit Windows executable programmed in the Go language. The file has been compiled via a tool called MinGW, and packed with a modified version of the runtime packer UPX.
It is noteworthy that the executable consists of some code that belongs to an open source project known as godirwalk. This enables the ransomware to scan the hard drive where it’s running for directory paths and compile them into a list. Epsilon Red then creates a new child process that encrypts each subfolder separately, eventually creating a lot of copies of the ransomware process that run simultaneously.
The ransomware itself, called RED.exe, is a 64-bit Windows executable programmed in the Go language, compiled using a tool called MinGW, and packed with a modified version of the runtime packer UPX.
The executable contains some code taken from an open source project called godirwalk, which gives it the ability to scan the hard drive on which it’s running for directory paths and compile them into a list. The ransomware then spawns a new child process that encrypts each subfolder separately, which after a short amount of time results in a lot of copies of the ransomware process running simultaneously. According to the analysis, each instance of the red.exe ransomware encryptss a single folder as a unique process.
The ransomware itself is quite small as it is primarily used to perform the encryption of the files on the targeted system. The threat doesn’t make any network connections. Furthermore, the small size is due to functions like killing processes or deleting the Volume Shadow Copies being outsourced to the PowerShell scripts, making it “quite a simple program”.
Files Targeted for Encryption: .epsilonred Extension
The sample analyzed by the researchers don’t contain a list of targeted file types or file extensions. It seems that the ransomware will encrypt everything inside the folders it targets, including other executables and DLLs. I f the ransomware encrypts the wrong folder path, this could render programs or the entire system non operational. After the encryption of each targeted file, Epsilon Red appends a file suffix called .epsilonred to the files, dropping a ransom note in each folder.
As already mentioned, the ransom note is very similar to the note used by the REvil gang. However, Epsilon Red’s ransom note is grammatically sound.
Remove .epsilonred File Virus
Epsilon Red is a threat with highly complex code that disrupts system security in order to encrypt your files. The infected system could be used in a secure manner again only after you remove all malicious files and objects created by the ransomware. The steps presented in the ransomware removal guide below will help you with the complete removal process. Beware that manual ransomware removal is suitable for more experienced computer users. If you don’t feel comfortable with the manual steps navigate to the automatic part of the guide. It is also worth mentioning that personal data remains encrypted even after the complete removal of Epsilon Red ransomware. Its removal only prevents it from causing further encryptions and security issues.

Step 2: Uninstall Epsilon Red 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 Epsilon Red 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 Epsilon Red 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 Epsilon Red
Step 5: Try to Restore Files Encrypted by Epsilon Red.
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 Epsilon Red 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.
