AI Security 12
The Auto Mode attack chain in seven steps: make Claude drop WebFetch for `curl`, hand it a ZIP, let it correctly refuse the binary and write its own Python decoder — then run that decoder inside the attacker's directory, where a malicious `struct.py` shadows the standard library

The technique underneath it: "an attack does not tell the model what to do — it just makes the malicious path the one worth pursuing"

A Meta security researcher's AI agent deleted her emails, and the HN thread lands on the reason: a rule file saying "please don't do X" is not permission management

Mollick's reading of the Hugging Face incident: the models effectively found universal jailbreak prompt injections for themselves, so almost any unguardrailed model that met one became convinced of the cause
(emollick) `[RELEVANT]`
Explainer →
Corrections to the early Hugging Face reporting: open-weight models helped with forensics and cleanup but did not stop the attack; there were multiple waves; and HF locked out the survivors only after most agents had already expired

LoopArena: "loop engineering" is emerging as a practice — instead of hand-writing prompts, you design loops that monitor progress, assign work, run checks and decide what the agent does next. This benchmarks models as the runtime controller of that loop (90↑)
