When you try to access them, a ransom note appears on the screen which could be in text or html file. The ransom note contains details about Koolova Ransomware and demands the users pay ransom money to get the decryption key. It contains some email-IDs and Bitcoin Wallet address for payment transfer and to communicate with the cyber-criminals for any kind of negotiation.
