Ransom Note

=== README === Greet citizen of the world. Your files have been encrypted by the NetForceZ's Ransomware. Your documents, photos, databases, and other important files have been encrypted with the strongest encryption and a unique key. The files are no longer usable as they have been encrypted. You cannot recover them without our help. To restore your files, you need to purchase a special decryption key. The price for the key is $500 USDT ERC20 on Ethereum Network. To buy the decryption program, you need to do the following: Your ID : 1. Create an account on Coinbase or Binance to buy $500 USDT ERC20 on Ethereum Network. 2. Install a USDT ERC20 on Ethereum Network Wallet like Exodus. 3. Send USDT ERC20 on Ethereum Network to us : Once you have USDT ERC20 on Ethereum Network in your Wallet, you must send the required amount to our USDT ERC20 on Ethereum Network address. 4. Confirm Payment : Notify us through Telegram with the transaction ID. After we confirm your payment, we will send you the decryption key. Warning: * Do not try to decrypt your files using third-party software; this may cause permanent data loss. * Do not rename the encrypted files or try to modify them in any way; this will prevent you from being able to decrypt them. * If you do not pay within 10 hours, your files will be permanently deleted. If you need proof that we can decrypt your files, you can contact us and decrypt one file for free.
