KillBot Ransomware – In-Depth Overview

KillBot is a cryptovirus that has the ability to encrypt your files and shows a window with instructions on your computer screen whether your files get encrypted or not. As the virus is still in its development phase your files might not get locked. The extortionists want you to pay a ransom for the alleged restoration of your files.

KillBot 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.

After the encryption process is initiated, the KillBot virus will display a ransom note on a grey background. You can the contents of that ransom message from the following screenshot given here:

The ransom note states the following:

The note of the KillBot ransomware states that your files are encrypted. However, you should NOT under any circumstances pay any ransom. Your files may not get recovered, and nobody could give you a guarantee for that. Moreover, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal acts.

KillBot Ransomware – Encryption Process

What is known for the encryption process of the KillBot ransomware is that the encryption algorithm implemented for locking up files is AES. Currently, the virus has not been reported to encrypt files and it seems that KillBot is in its development stage. However, the encrypting ability is there, inside the malware’s code, but not yet used. Registry entries could be deleted and if all functions and features of the ransomware are unlocked, it will become a serious threat to computer systems.

After the ransomware comes out of its development phase it would most probably encrypt files from the following types:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

The KillBot 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 above-stated command is executed that would make the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data. If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore your files back to normal if they got encrypted.
