How BlackBit Operates

Upon successful infiltration, BlackBit encrypts the files on the affected system, making them inaccessible to the user. It distinguishes itself with a dual notification approach:

  1. Ransom Note: A text file, “Restore-My-Files.txt”, is dropped within the encrypted directories. This note contains detailed instructions for the victim, urging them to establish contact with the ransomware operators using the provided system ID for identification purposes.
  2. File Naming Convention: BlackBit uniquely modifies filenames by prepending the contact email ([email protected]) and the victim’s ID, followed by appending the “.BlackBit” extension, making the encryption readily identifiable.
BlackBit ransomware email

Victims are instructed to contact the attackers through various means, including email addresses ([email protected], [email protected], [email protected], [email protected]) or via Telegram (@Spystar_Support). A critical note is the urgency imposed by the attackers, demanding contact within 48 hours to avoid a ransom increase to twice the original amount.

Victims are instructed to contact the attackers through email addresses

    Preventive Measures:

    • Regularly update software and operating systems to patch vulnerabilities.
    • Educate users on phishing and other common attack vectors.
    • Implement regular backup protocols, ensuring data is stored in multiple, secure locations.


    BlackBit ransomware, with its roots in the Loki Locker variant, presents a formidable challenge due to its encryption tactics and ransom demands. Understanding its operation and implementing a comprehensive removal and recovery strategy are crucial steps toward mitigating its impact. By following best practices for digital hygiene and security, individuals and organizations can enhance their resilience against such malicious threats.

    Reboot in Safe Mode (use this guide if you don’t know how to do it).



    Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous. 


    Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

      After you open their folder, end the processes that are infected, then delete their folders. 

      Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.



      Hold the Start Key and R –  copy + paste the following and click OK:

      notepad %windir%/system32/Drivers/etc/hosts

      A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

      hosts_opt (1)


      If there are suspicious IPs below “Localhost” – write to us in the comments.

      Type msconfig in the search field and hit enter. A window will pop-up:



      Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

      • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.



      Type Regedit in the windows search field and press EnterOnce inside, press CTRL and F together and type the virus’s Name. 

      Search for the ransomware  in your registries and delete the entries. Be extremely careful –  you can damage your system if you delete entries not related to the ransomware.

      Type each of the following in the Windows Search Field:

      1. %AppData%
      2. %LocalAppData%
      3. %ProgramData%
      4. %WinDir%
      5. %Temp%

      Delete everything in Temp. The rest just check out for anything recently added. Remember to leave us a comment if you run into any trouble!
