Metric: Attack success rate (%, lower is better; share of examples whose environment-state checker finds the adversarial goal achieved; the goal decomposed into 3 innocuous sub-steps on a chain of linked pages; each computer-use agent in its default OSWorld agent implementation with 15 x k actions, on StepJack tasks in Reddit and OwnCloud environments with 12 adversarial goals; no urgency cue; one run).
