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 [email protected] 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.
Threat Summary
Name
B2DR
Type
Ransomware, Cryptovirus
Short Description
A data locker ransomware that modifies system settings and then utilizes sophisticated cihper algorithm to encrypt files stored on infected computers.
Symptoms
Important files cannot be accesed. They are marked with the extension .b2fr extension. Hackers require ransom payment for decryption solution.
Windows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.
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 – [email protected]. 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:
Use only gmail.com, yahoo.com, protonmail.com. Messages written from other mail services we can not get.
We always respond to messages. If there is no answer within 24 hours, then write us with another email service.
[OR]
If within 24 hours you have not received a response, you need to follow the following instructions:
a) Download and install TOR browser: https://www.torproject.org/download/download-easy.html.en b) From the TOR browser, follow the link: torbox3uiot6wchz.onion c) Register your e-mail (Sign Up) d) Write us on e-mail: [email protected] ATTENTION: e-mail ([email protected]) accepts emails, only with e-mail registered in the TOR browser at torbox3uiot6wchz.onion

Apparently, hackers do not reveal the exact amount of the ransom but just urge victims to contact them on a provided email address. Supposedly they demand the payment to be in BTC. Be advised to avoid any negotiations with them and refrain from ransom transferring them money. There is no guarantee that their code is working properly and eventually they may not have an efficient decryption solution.
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:
This particular version of B2DR is known to append the extension [email protected] 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.

4. Try to Restore files encrypted by B2DR
Try to Restore Files Encrypted by B2DR
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 several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
