→ HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run “Microsoft Update System Web-Helper” = “C:\Windows\System32\notepad.exe %UserProfile%\Desktop\README.txt”

The ransom note of .THANATOS, is named README.txt and it aims to scare the victims off into paying ransom. What is particularly interesting about it is that this variant of Thanatos is the first ransomware to ask a ransom payoff in BitCoin Cash:

  • Videos.
  • Images.
  • Audio files.
  • Backups.
