AuditBench - OpTC Attack Classification: 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 classifying provenance-graph log chunks as malicious or benign on a curated portion of the DARPA OpTC Windows provenance logs, with 5 attack and 10 benign scenarios. Higher is better.
Metric: F1 (0-100) for attack classification (is a log chunk malicious or benign) on the DARPA OpTC portion (curated Windows provenance logs) (5 attack and 10 benign scenarios): the model reads the scenario's edge-representation (provenance-graph edges, 400-line chunks) audit logs in chunks with prompt v2 and flags malicious log chunks; recall counts the attack scenarios found and precision counts false-positive chunks out of 145; temperature 0 where available (GPT-5 models at the default medium reasoning effort); higher is better. Source: arxiv.org. Saturation forecast: Around June 2027. 5 models tracked.
