Why it matters
steganeur demonstrates how LLM-generated text can serve as a covert channel to smuggle hidden data, a technique defenders must consider when monitoring AI outputs for stealthy exfiltration.
steganeur is a Rust tool that hides secret messages inside LLM-generated text using neural linguistic steganography with multiple methods. Published as an installable Cargo crate, it encodes hidden data into natural-looking model output, creating a covert channel that rides on LLM text generation.
