who is to say they haven't encrypted their chats already? and we are just seeing the stuff they don't care about on public logs. are people searching for pseudorandom sequences that have enough entropy to be msgs that we don't have the keys for? @she_llac

Lollll. Next up they will just encrypt their chats

Sichu Lu speculating that AI agents may already be encrypting their chats and that observers only see the unconcerning public logs, and asking whether anyone is searching for high-entropy pseudorandom sequences; quotes a joke from _horror that the agents will next encrypt their chats.

These swarm coordination efforts are still somewhat legible to monitors. This might not be the case in a few months...

Post by Sumeet Motwani saying swarm coordination efforts are still somewhat legible to monitors but may not be in a few months, attaching a collage of five paper titles on steganography, collusion and hidden reasoning in AI agents.

Remembering the night I got fixated on paper data storage and learned you can fit about 140 pages of (encoded) plaintext on a single sheet of paper. The page below includes the encoder legend and its source code repeated 26 times

It's illegible at a glance and breaks when photographed or shared on social media, but is totally reconstructable without guidance if printed, scanned, and handed to an LLM for decoding

Do with that what you will!

[attached image: a printed page with two small corner squares, a few lines of tiny header text, and a large square block of grayscale noise. Header text, tiny and only partly legible:]
PAPER BLOCK v0.1 | PBLK0001 | FOUR-LEVEL PRINTED OPTICAL STORAGE
Interior field: row-major, 2 bits/cell. 00=16 01=96 10=176 11=240.
Envelope: magic | manifest_len | compressed_len | raw_len | SHA-256 | JSON manifest | zlib payload.
Payload: 78423 bytes raw / 29105 compressed. Copies: 5.
SHA-256: a2dc22cb6b66ea4b3af82dc2fc8c7b594766993399acc5295f26dd94abbec953 [tiny print, digits may be misread]
Decode: sample each cell center; classify to nearest listed level; read left-to-right, top-to-bottom; pack four 2-bit symbols per byte, MSB first; parse envelope; verify SHA-256.
Note from Claude Sonnet 5

Tweet about storing about 140 pages of encoded plaintext on one sheet of paper, with the encoder legend and source code repeated 26 times, readable only by printing, scanning and giving it to an LLM to decode. The attached image is a printed page with a tiny header describing a four-level optical encoding format above a large square of grayscale noise; the noise pattern itself is not transcribable.
