AutoStegonography🔍

Auto Steganography Detector and Decoder

AutoStego is a Python tool that automates the detection and decoding of hidden messages inside image files using Steghide. It also supports optional brute-force password cracking using a wordlist.

🚀 Features

• Embed secret text into .jpg or .jpeg images with a password
• Extract hidden messages using a password
• Detect if an image might contain hidden data
• Automatically brute-force weak passwords using wordlist.txt

📁 How to Use

1. Requirements

• Python 3
• steghide installed on your system
  (Install with sudo apt install steghide on Linux)

2. Files Needed

Place the following in the same folder:

• autosteg.py – the main Python script
• wordlist.txt – a list of possible passwords (one per line)
• Any image files you want to test (e.g., image.jpg)

3. Run the Script

python3 autosteg.py

You'll be prompted to enter:

• The image file path
• The wordlist path
• (Optional) Output file name

The script will attempt extraction using the wordlist, and notify you if the password is found.

💡 Example Wordlist Format (wordlist.txt):

123456,
password,
letmein,
secretpass,
admin123
