BlackSheep Ransomware – More Information

BlackSheep is a virus that encrypts your files and extorts you to pay a ransom to get them back to normal. The interesting thing about the virus is that it will lock your desktop and display a fake Windows Update screen on top to make it look like a legitimate update for the operating system as seen below:

BlackSheep ransomware could make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

You can view the ransom message that loads after the encryption process in this picture:

That ransom message reads the following:

BLACKSHEEP RANSOMWARE
YOUR COMPUTER IS HACKED

ENTER KEY | DECRYPT

The note of the BlackSheep ransomware states that your files are encrypted and that even your computer screen is hacked. It may have a screen-locking function, but know that your PC should still be accessible. A ransom sum of 500-US-dollar-worth of Bitcoins is demanded as payment for potentially unlocking your files. If 54 hours pass, the ransomware authors threaten to get mean. That is probably an empty threat or it means that if you decide to pay later, they won’t send a decryption key.

That shouldn’t worry you as malware researchers say that the ransomware is decryptable. You should NOT under any circumstances pay the ransom. Your files may not get restored, and nobody could give you a real guarantee. Moreover, giving money to cybercriminals will likely motivate them to create more ransomware or do other criminal activities.

BlackSheep Ransomware – Encryption Process

The BlackSheep ransomware seeks to encrypt files from the following file types:

  • Databases
  • Texts
  • Images
  • Videos
  • Music

All of the files that get encrypted will receive the same extension appended to them, and that is the .666 extension.

The BlackSheep cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

In case the command stated above is executed that would make the encryption process more efficient as it will eliminate one of the ways for restoring your files. If your PC was infected with this ransomware and your files are locked, read on through to find out how you could potentially recover your data.
