AuditBench - OpTC Lateral Movement: leaderboard
AuditBench (2026) evaluates LLMs on security investigations over system audit logs read in 400-line chunks. This board is the F1 score (0 to 100) for finding the log lines of 19 lateral-movement events in a curated portion of the DARPA OpTC Windows provenance logs. Higher is better.
Metric: F1 (0-100) for lateral-movement identification on the DARPA OpTC portion (curated Windows provenance logs) (19 lateral-movement events): the model reads the scenario's edge-representation (provenance-graph edges, 400-line chunks) audit logs in chunks with prompt v2 and flags the log lines of the lateral movement; recall counts the attack scenarios found and precision counts false-positive log lines; temperature 0 where available (GPT-5 models at the default medium reasoning effort); higher is better. Source: arxiv.org. Saturation forecast: Around May 2028. 5 models tracked.
