A medium interaction SSH honeypot backed by a basic LLM that believes it's bash.
I'm impressed at the ability to retain limited state, and respond 'reasonably enough' that it'll probably allow first stage automated attacks to be captured.. but at the moment, it's way too easy to peer behind the curtain.
It's quite jarring when your bash terminal starts telling you a story about a happy dragon in response to some weird command.

Once upon a time, in a land far, far away, there lived a magnificent dragon named Scorch. Scorch was the most feared creature inall the land, with scales that shone like gold in the sunlight and eyes that glowed like embers. He roamed the countryside, breathing fire and destruction wherever he went, andnoone dared to cross...
Tempting, but in order to reduce the potential attack surface, I'm likely just to create a simple simulator instead now.
If it's good enough to fool the first few interactions of an automated script, that'll probably do. That'll give me the curl/wget target they're trying to insect me with, most likely.
It means I can potentially create a single binary docker instance that can be reset practically instantly by deleting/reimporting.

Maybe backed by AppArmor or SELinux to prevent breakouts
