🛠️ Tool
===================
Conversation Stenography is a proof of concept tool that hides secret messages inside normal-looking chat text using local AI models.
🔹 Key Features
• Generates innocent cover text for encrypted messages
• Works across any messaging platform like WhatsApp or Signal
• Uses local GPT-2 model for generation and decoding
🔹 Technical Implementation
The tool is written in Go. It clones from GitHub, builds a binary, and downloads a recommended local AI model on first run. It encrypts the message and then uses the local model to generate a cover text that looks like a normal conversation. A local simulation mode allows testing with two users on one device.
🔹 Use Cases
• Educational demonstration of LLM-based steganography
• Covert communication research against message scanning
🔹 Limitations
The author explicitly states this is a proof of concept with multiple issues. Techniques are already being developed to detect hidden content in text. The author notes they are 18 and not the first to explore this, acknowledging LLM-based steganography has existed for years and may already operate at scale.
