RansomwareSim is a simulated ransomware application developed for educational and training purposes. It is designed to demonstrate how ransomware encrypts files on a system and communicates with a command-and-control server. This tool is strictly for educational use and should not be used for malicious purposes.

• Encrypts specified file types within a target directory.
• Changes the desktop wallpaper (Windows only).
• Creates&Delete a README file on the desktop with a simulated ransom note.
• Simulates communication with a command-and-control server to send system data and receive a decryption key.
• Decrypts files after receiving the correct key.

Important: This tool should only be used in controlled environments where all participants have given consent. Do not use this tool on any system without explicit permission. For more, read SECURE
