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:

Your files were encrypted with AES-256.

Some malicious scripts may modify the registry entries of your computer to change different settings. This is why manual clean up of your Windows Registry Database is strongly recommended. Since the tutorial on how to do this is a bit lenghty, we recommend following our instructive article about fixing registry entries.

2. Find malicious files created by B2DR on your PC

Find malicious files created by B2DR

1. For Windows 8, 8.1 and 10. 2. For Windows 7,XP and Vista.

2. Restore files encrypted by B2DR

Restore Files Encrypted by B2DR

Ransomware infections like B2DR aim to encrypt your files using an encryption algorithm which may be very difficult to directly 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 they may not be 100% effective but they may help you little or a lot in some situations.

Method 1: Scanning your drive’s sectors by using Data Recovery software.
Another method of 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:

• Stellar Phoenix Data Recovery Technicians License(Pro version with more features)
• Stellar Phoenix Windows Data Recovery
• Stellar Phoenix Photo Recovery

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:

• Kaspersky Decryptors
• Emsisoft Decryptors

Urgent! It is strongly advisable to first remove the B2DR threat before attempting any decryption, since it may interfere with system files and registries. You can do the removal yourself just in 5 minutes, using an advanced malware removal tool.

Method 3: Using Shadow Explorer

To restore your data in case you have backup set up, it is important to check for shadow copies in Windows using this software if ransomware has not deleted them:

• Shadow Explorer

Method 4: Finding B2DR decryption key while it communicates it via a network sniffing software.

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:
