Exactly. I thought this is exactly what Anthropic's Project Glasswing was meant to be, and targeted at critical internet infrastructure.

Either Mythos is useless and didn't find this (hint: Opus 5.5 will find this once it knows where to look)... or, they did find it, and this is one of many vulnerabilities they're covering up via "guardrails".

I'll be a lot happier if I wake up tomorrow and find this was found with help from Anthropic (or even OpenAI) but I won't hold my breath.
