This article provides information on how to remove easily remove B2DR ransomware and how to restore .b2fr files without paying the ransom.
Another variant of B2DR ransomware has been spotted by security researchers. It is known to encrypt sensitive files with AES-256 cipher and append the extension .ssananunak1987@protonmail.com.b2fr to corrupted files. At the end of the attack, this newly discovered B2DR version drops a file called Readme.txt that contains ransom message left by hackers. In case that you fell victim to this threat be advised to avoid any negotiations with cyber criminals as they can only steal your money without providing you working decryption solution.

B2DR Ransomware – Distribution
One of the possible ways to infect your device with B2DR ransomware is to visit a compromised web page that is set to install it directly on your PC. As regards the links to such pages they can be pushed by various advertising campaigns, posted on social media channels or presented in email spam messages.
Another way to grant B2DR crypto virus access to your system is to open a file attached to an email message. Often bad actors embedded the ransomware payload on documents and spread them with email spam messages. Beware and practice caution before you decide to download and open files from the emails you receive even when they seem legitimate. It is a common practice of hackers to pose as representatives of well-known companies, services, websites and even governmental institutions in an attempt to trick you into infecting your PC with devastating infections like B2DR ransomware virus.
It is also possible to execute unnoticeably the ransomware payload during the installation process of a desired free third-party app as the infection code may be incorporated into the installer.
B2DR Ransomware – More about the Infection Process
Security researchers discovered another version of B2DR ransomware that is known to encrypt important files in order to extort a ransom payment from victims. It is associated with the specific extension pattern it uses to mark all corrupted files – .ssananunak1987@protonmail.com.b2fr. By reaching the end of the article, you will know how to remove the threat and how to restore .b2fr files.
Before the encryption stage, B2DR crypto virus initiates several other actions in order to plague the system and ensure its persistent presence. The infection begins at the moment when its payload is executed on the system. With the help of the payload, the ransomware may create additional malicious files or drop ones from its command and control server.
Some of the files are likely to take over essential system processes in order to utilize their functionalities while remaining undetected by active security measures. And as long as files and objects associated with B2DR ransomware are present on your system, they may be used by hackers to install additional data stealer malware in order to obtain financial credentials and logins.
In order to fulfill one of the main stages of the attack which is ransom note display, B2DR (.b2fr) ransomware is believed to access Registry Editor and modify the settings of some of the keys located there. In the majority of cases threats of this kind affect Run and RunOnce registry sub-keys as they manage the automatic execution of all paramount system files on each system start. So by adding malicious values under these keys, B2DR could automatically open the file that contains its ransom note – Readme.txt. And the whole ransom message reads:
Your files were encrypted with AES-256.

B2DR Ransomware – Data Encryption
Primarily, B2DR ransomware aims to encrypt important files so you can’t use them. For the purpose, it utilizes a built-in encryption module that implements AES-265 encoding to all target types of files. Supposedly the ransomware is designed to corrupt the following files:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
After encryption files are marked with a sequence of two extensions that follow the pattern:
- .[hacker contact email address].[malware extension]
This particular version of B2DR is known to append the extension .ssananunak1987@protonmail.com.b2fr to encrypted data. Unfortunately, you can’t access the information stored by this files until you apply any efficient data recovery solution. So keep reading and find some suggestions made in our guide.

Step 2: Uninstall B2DR 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 B2DR 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 B2DR 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 B2DR
Step 5: Try to Restore Files Encrypted by B2DR.
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 B2DR 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.
