Ask HN: Secret messages in public forums

9 points

6 years ago

You might be familiar with movies/series where hidden/secret messages in public online forums/channels are part of the plot (involving some form of steganography).

Have you ever encountered such a situation (e.g., Reddit, or even HN)?

N.B. The staggeringly elaborate Cicada 3301 puzzle [1][2] does require deciphering steganographic messages, but they aren't posted in public channels.
