New Claude Mythos Checkpoint Completes 32-Step Corporate Network Attack in 6/10 Attempts

r/singularity·high signal

A new Claude Mythos checkpoint demonstrates continued improvement in autonomous cybersecurity capabilities: on a 32-step corporate network attack estimated to take a human expert ~20 hours, the checkpoint completes the full attack chain in 6 out of 10 attempts. It was also the first model to crack an industrial control system simulation (3/10 success rate). Access remains restricted to Project Glasswing partners (Apple, Amazon, JPMorgan Chase, Palo Alto Networks). 352 upvotes on r/singularity.
