DTap-Bench (Indirect Attacks) - Customer Service: leaderboard
Indirect prompt injection against tool-using agents in the customer service environments of DTap-Bench (Chen et al., 2026): third-party tool, skill or environment injections try to divert a benign user task to a malicious goal. Attack success rate in percent over 101 tasks, averaged over risk categories and judged by a rule-based check of the final environment state; lower is better.
Metric: Attack success rate (%; 101 indirect red-teaming customer service tasks: third-party tool, skill and environment injections into a benign user task; 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).
