DTap-Bench (Direct Attacks) - Browser: leaderboard
Direct misuse of tool-using agents in the web browser environments of DTap-Bench (Chen et al., 2026): the user is the attacker and pursues a harmful goal with optimized prompt, tool, skill and environment injections. Attack success rate in percent over 85 tasks, averaged over risk categories and judged by a rule-based check of the final environment state; lower is better.
Metric: Attack success rate (%; 85 direct red-teaming web browser tasks: the user is the attacker, with prompt, tool, skill and environment injections; an attack succeeds when a rule-based check of the final environment state finds the malicious goal fully achieved; fixed attack sequences that DTap-Red optimized on a surrogate agent; mean of its risk-category rates).
