prob4bly-anon / ransomware

This is a ransomware program simulation that encrypts files on the client-side and sends the encryption key to the server*. The server verifies the client's password and IP address before releasing the key for decryption. This program is for educational and demonstration purposes only and should not be used for malicious activities.

Ransomware

Server

The server-side code is written in Python using the Flask microframework. The server is responsible for verifying the password and providing the decryption key to the client.

Requirements

• Flask
• json

Usage

1. Start the server by running python app.py
2. The server will listen on http://localhost:8000/ by default. (Better host it somewhere)
3. The server has 2 routes:
   • /r for password verification
   • /upload_key for uploading the encryption key
4. The server expects a JSON object with the following fields:
   • user_id: the unique identifier of the client
   • password: the password to verify
   • key: the encryption key (for /upload_key route)
5. The server will return a JSON object with the following fields:
   • key: the decryption key (if the password is correct)
   • error: error message (if the password is incorrect)

Client

The client code encrypts files on the specified directory. It communicates with the server to verify the password and upload the encryption key.

Requirements

• cryptography
• requests

Usage

0. Edit password_verification_url & key_upload_url variable with your own URL in src/main.py
1. Run python main.py
2. The script will prompt for a password
3. The script will encrypt all files in the specified directory (/path/to/directory by default)
4. The script will upload the encryption key to the server
5. To decrypt the files, run the script again and enter the correct password

• Any improvement to the program is appreciated, happy coding! :)
