Analysis of KKK Ransom Virus

After an infection by KKK ransomware takes place, the virus begins to immediately situate it’s malicious files on the compromised computer. These files the following:

  • A randomly named executable file.
  • A Facebook.exe file.

After the files have been dropped on the infected computer, they may be automatically executed by their loader or the infection file that distributes KKK ransomware. When they are executed, these files have functions in them that make them perform different activities on the compromised computer. One of those activities is to gain administrative permissions. This allows the KKK ransomware to interact with key components of the Windows OS, such as modify the Windows Registry Editor, more specifically it may attack the following sub-keys:

→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

Modifying these Windows sub-keys assures that the KKK virus may run on Windows boot.

After this has been completed, the ransomware virus may also interfere with the Windows Command Prompt in order to delete the shadow copies from the infected computer. This may be achieved via the following administrative commands in Windows:

→ process call create “cmd.exe /c
vssadmin.exe delete shadows /all /quiet
bcdedit.exe /set {default} recoveryenabled no
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures

KKK Ransomware – Encryption

The encryption process of the KKK ransomware infection is conducted via the Advanced Encryption Algorithm. This cipher, also known as AES is one of the top encryption algorithms used today for protecting data. It’s procedure includes replacing the data from the original file with data from the cipher. This procedure results in the file no longer able to be opened and having the .KKK file extension added to it. The files encrypted by this ransomware may look like the image below:
