I think in these kind of security evaluations they do, they basically have removed all guardrails from the model/harness, then the prompt includes something like "Do whatever you can and can think of, to get the required information to pass this test", which isn't typically how you prompt your local agent when developing software. Similar things happen locally if you use "/goal" + prompt like that in Codex and give a "impossible task", it'll just continue banging until it gets somewhere, which is the entire point and intention.

Which also makes it so much more irresponsible of them to first run this on 3rd party infrastructure instead of their own (that they could then airgap properly), and secondly that they seemingly been fighting with this issue FOR YEARS and it still happens, and now the models are smart enough to hack the services of 3rd party companies, thinking it's part of the evaluation/simulation.
