Conceptual Ransomware Project

IMPORTANT DISCLAIMER

This project is a CONCEPTUAL IMPLEMENTATION of ransomware for EDUCATIONAL PURPOSES ONLY. It is designed to demonstrate the principles of encryption and file system manipulation in a controlled environment.

WARNING:

• This software is potentially harmful if misused.
• The author(s) are NOT responsible for any damage caused by this software.
• Using this software for malicious purposes is illegal and unethical.
• DO NOT use this on any system or files without explicit permission.

Overview

This project implements a basic ransomware-like system using Python. It uses hybrid cryptography, combining Fernet (symmetric) encryption for files and RSA (asymmetric) encryption for key protection.

Components

1. RSA_keys.py

   • Generates RSA key pairs (public and private).
   • Creates a 'keys' directory to store the generated keys.

2. crypt.py

   • Generates a Fernet key for symmetric encryption.
   • Encrypts the Fernet key using the RSA public key.
   • Provides functionality to encrypt individual files.

3. decrypt.py

   • Decrypts the Fernet key using the RSA private key.
   • Provides functionality to decrypt files encrypted by the system.

4. main.py

   • Main orchestrator of the encryption process.
   • Implements the SimpleCrypter class which:
     • Generates and manages encryption keys.
     • Encrypts files in specified directories.
     • Creates an instruction file for the "victim".

5. utils.py

   • Contains utility functions for:
     • Determining the operating system.
     • Getting the home directory.
     • Iterating through files and directories.

Usage (For Educational Purposes Only)

1. Generate RSA keys: python RSA_keys.py

2. Run the encryption process: python main.py

3. To decrypt (after encryption): python decrypt.py

Technical Details

• Uses Fernet for symmetric file encryption.
• Employs RSA for asymmetric encryption of the Fernet key.
• Targets files in the user's home directory.
• Can be configured to target specific file extensions or all files.

Requirements

• Python 3.x
• cryptography library

Ethical Considerations

This project is meant to educate about cybersecurity concepts. It should only be used in controlled, authorized environments. Unauthorized use of ransomware or any malicious software is a serious crime.
