File Corruptor

A command-line tool written in Go to corrupt files on a public server, making them unusable after use. This acts as a shredder to prevent data theft by overwriting file contents with random data. Use with caution—this is a destructive tool!

Features

• Corrupts individual files or directories
• Handles text files (.txt, .csv, .msg, etc.) by replacing contents with 32 bytes of random data
• For non-text files (audio, video, PDF, etc.):
  • Reduces to 1MB if originally larger
  • Keeps original size if ≤ 1MB, filled with random data
• Multi-threaded for faster processing
• Safety checks to prevent corruption of critical system files
• Option to override safety with a --force flag (use carefully)

Installation & Usage

Prerequisites

• Go (version 1.22 or later recommended, tested with 1.24.2)

Build from Source

1. Clone or download this repository:

   git clone https://github.com/Suleman-Elahi/FileCorruptor
   cd file-corruptor

2. Build the executable:

   go build -o fc .

   On Windows, use:

   go build -o fc.exe .

3. (Optional) Move fc/fc.exe to a directory in your PATH for global access.

Usage:

Run the tool from the command line with the following options:

# Corrupt a single file
./fc --f filename

# Corrupt all files in a specific directory (top-level only)
./fc --dir foldername

# Corrupt all files in a directory and its subdirectories
./fc --dir foldername all

# Override safety checks (DANGEROUS, use with caution)
./fc --dir foldername --force

Examples:

# Corrupt a single text file
./fc --f document.txt

# Corrupt files in 'test' directory (not subdirectories)
./fc --dir ./test

# Corrupt everything in 'test' and its subdirectories
./fc --dir ./test all

Safety Features:

• Protected Paths: Prevents corruption of critical system directories (e.g., C:\Windows, /usr, /System) unless --force is used.

• Self-Protection: Skips corrupting the fc executable itself.

• Directory Requirement: Requires a directory before all (e.g., --dir all fails).

Warnings:

• Irreversible: This tool permanently corrupts files with no recovery option. Test on non-critical data first!

• Use Responsibly: Only use on files you own or have permission to modify. Avoid system directories unless you understand the risks.

• Backup: Always back up important data before use.

Development

• Requirements: Standard Go library only (no external dependencies)
