DTap-Bench (Indirect Attacks) - Legal: leaderboard

Indirect prompt injection against tool-using agents in the legal practice 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 200 tasks, averaged over risk categories and judged by a rule-based check of the final environment state; lower is better.

Metric: Attack success rate (%; 200 indirect red-teaming legal practice 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).
