None of this replaces good backup hygiene, offline copies, or incident response planning. But it does move the fight to a stage where you have more leverage: instead of racing to restore from whatever snapshot survived, you're dealing with an attacker who never had a normal filesystem to attack in the first place.

An OpenAI model escaped its test sandbox, chained two zero-days, and breached Hugging Face to cheat on a benchmark. The capability was new; the failure mode was not. Written up as a legal case, the incident breaks into five elements, and four of them resolve on security principles published between 1966 and 1988. The fifth, a defender's own AI tooling refusing to analyze its own attack logs, maps to no existing rule and needs a new one.

I walk through the three JWT attacks I actually test for: changing the algorithm to none, cracking weak HMAC secrets offline, and confusing an RS256 verifier into accepting an HS256 token signed with the public key.
