How to remove BlackByteNT ransomware

BlackByteNT is a malicious program that locks users' personal files using encryption algorithms

BlackByteNT ransomware is a virus that infects computer networks and encrypts important files like documents, photos, videos, and databases. Because it employs complex encryption algorithms, this type of malware can result in permanent data loss. In most cases, decrypting the files is impossible without the assistance of the cybercriminals responsible.

Once infected, this ransomware variant appends a random string of characters and the .blackbytent extension to each encrypted file and replaces their icons with blank pages. Shortly after the encryption process is completed, the victim receives a ransom note, which is a message from the attackers explaining their demands.

The ransom note

The BB_Readme_[random_string].txt ransom note reads as follows:

BLACKBYTE NT

The message provided is a ransom note from an unknown entity known as “BLACKBYTE NT,” which claims to have encrypted all of the user's files and stolen their confidential data. The message instructs the user to take specific steps in order to decrypt the files and prevent data leaks.

The first step is to download and install the TOR Browser from the provided link, and then paste the URL into the browser to be redirected to the chat where all the information needed for decryption will be provided. The note also states that the user's files are already up for auction in the entity's auction, and the longer the user waits, the higher the price. If the user does not contact the entity within four days, they will forfeit their opportunity to be decrypted.

However, paying the ransom in such cases is strongly discouraged because it may result in the entity's criminal activities being supported. Even if the ransom is paid, there is no guarantee that the entity will provide the decryption key or recover the files. Furthermore, paying the ransom encourages such criminal activity and may make the user a target for future attacks.

Distribution methods

This ransomware's distribution method is unknown, but cybercriminals typically exploit various software vulnerabilities^[1] to gain access to systems. This makes it critical to update both the operating system and software on a regular basis to ensure that all available patches are installed. Developers release updates on a regular basis, and they should be installed as soon as possible.

Email is another common method of ransomware distribution. This approach has the greatest impact on work environments because people frequently use programs like Office 365 to open files sent to them at work. Attackers exploit this by attaching infected files to their messages.

To make these emails appear legitimate, phishing techniques are frequently used. Some phishing attempts may appear to be sent by coworkers, but hackers can also gain access to friends' contact lists and impersonate them. If users are not expecting any attachments, they should always double-check with the person via another platform.

Individuals can also become infected by downloading “cracked” software,^[2] though this scenario is more likely to occur among home users because downloading questionable files on a work computer is uncommon. These programs frequently include malicious code or malware in the installer, which users may overlook because they rush through the installation process.

Disconnect the device from the local network

To prevent the virus from spreading throughout the network, it is crucial to isolate the affected machine immediately. Once a single machine is infected, the malware can quickly spread through the network and encrypt files on other machines, including Network Attached Storage (NAS) devices. If a computer is connected to a network, it is essential to isolate it to prevent re-infection after removing the ransomware.

The simplest way to disconnect a PC from all networks is to unplug the ethernet cable. However, in a corporate environment, this may be difficult and time-consuming. The method below can be used to disconnect from all networks, including local and internet, and isolate each machine involved.

• Type in Control Panel in Windows search and press Enter
• Go to Network and Internet
• Click Network and Sharing Center
• On the left, pick Change adapter settings
• Right-click on your connection (for example, Ethernet), and select Disable
• Confirm with Yes.

If you are using some type of cloud storage connected to, you should disconnect from it immediately. It is also advisable to disconnect all the external devices, such as USB flash sticks, external HDDs, etc. Once the malware elimination process is finished, you can connect your computers to the network and internet, as explained above, but by pressing Enable instead.

Remove the malicious program

Attempting to recover your data before removing the malicious files can result in permanent data loss, and the ransomware may encrypt your files again. It is not advisable to attempt to remove the malware yourself. Instead, use anti-malware tools like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes to scan your system. These security software programs can automatically find all related files and entries and remove them for you, reducing the risk of leaving traces behind.

If the virus prevents you from using security software, you must first access Safe Mode.^[3] If you are unsure how to access Safe Mode, please refer to the instructions at the bottom of this post.

File recovery options

Without a backup, your files may be permanently lost as the decryption key is held by the hackers. Although third-party data recovery software can attempt to recover the files, they may not always be able to decrypt them. However, we recommend trying this approach. Before attempting data recovery, it is crucial to copy the corrupted files to a separate storage device such as a USB flash drive. It's important to note that you should only proceed with data recovery if you have already removed BlackByteNT ransomware from your system.

1. Download Data Recovery Pro.
2. Double-click the installer to launch it.
3. Follow on-screen instructions to install the software.
4. As soon as you press Finish, you can use the app.
5. Select Everything or pick individual folders where you want the files to be recovered.
6. Press Next.
7. At the bottom, enable Deep scan and pick which Disks you want to be scanned.
8. Press Scan and wait till it is complete.
9. You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
10. Press Recover to retrieve your files.

Repair the operating system after an attack

Malware infections can cause performance, stability, and usability issues, which can result in the need for a complete Windows reinstallation. These infections can modify the Windows registry database, damage crucial bootup sections, delete or corrupt DLL files, and more. Unfortunately, antivirus software cannot repair a system file that has been damaged by malware.

To address these issues, a maintenance tool like FortectIntego has been developed. This tool can repair many of the problems caused by malware infections, including Blue Screen errors, freezes, registry errors, damaged DLLs, and more. With the help of this tool, you may be able to avoid the need for a complete Windows reinstallation.
