Ransom Note

Hello, Congrats you have been hit by the Scrypt Ransomware so lets talk about recovering your files. First off don't even waste your time with free decrypters. Scrypt Ransomware uses 256 aes bit encryption which means its impossible to bruteforce or attempt to recover your files. So here are the steps to recovering your files. First off let me prefix this by saying reporting this malware or leaving a bad review on the product will instantly disqualify you from recovering your files, so if you wish to see your files in any shape or form I reccomend you keep quiet and follow these steps: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1. Download BitPay: https://bitpay.com/ This can also be downloaded from the microsoft store. 2. Purchase $500 in bitcoin using the buy crypto option 3. Send that $500 in bitcoin to this addr: {_BITCOIN_ADDR} 4. After you have sent the money send an email to {_EMAIL} saying that you have paid and please include your user id. 5. Wait roughly 6 hours, I will send you your decrypter and key which can be used to decrypt all files encrypted by the ransomware. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ YOU HAVE ONE WEEK, AFTER ONE WEEK DECRYPTING YOUR FILES WILL BECOME $5000 REPORTING THIS FILE TO ANYONE WILL RESULT IN A FULL LOSS OF FILES FAILING TO PAY WILL RESULT IN YOUR PERSONAL DETAILS SUCH AS: - IP - Address - Username - Emails and passwords - Discord Account BEEN SOLD ON THE DARKWEB
