The paper introduces AHLERT, a system that automatically extracts environment-aware hunt leads from Cyber Threat Intelligence reports. It combines a hybrid retriever—dense vector search plus multi-hop knowledge‑graph traversal seeded with MITRE ATT&CK—with ontology‑grounded retrieval‑augmented generation to constrain leads to a defender’s assets. Evaluations on public CTI reports show that AHLERT doubles mean F1 scores and achieves an effectiveness score of ~86.95% compared to off‑the‑shelf LLM models.

arXiv:2607. 24563v1 Announce Type: new Abstract: Security Operations Centers increasingly rely on automated mapping of Cyber Threat Intelligence reports to MITRE ATT&CK, yet extractor outputs remain fallible and are often stored without the evidence, provenance, and validation history needed to decide whether an individual mapping should be trusted.

The paper audits the reproducibility of knowledge‑graph extraction from threat reports by re‑implementing matching rules for only five of twelve systems and re‑scoring ten system outputs under eight protocols. The audit shows that different matching protocols can reverse most pairwise system rankings and that a fixed prediction set can vary from 0.16 to 0.70 F1. The authors also build CTIForge to isolate validation effects, finding that validation changes precision across backbones and increases entity‑type disputes, and they release the full pipeline, protocol suite, and audit records.

arXiv:2606. 03453v1 Announce Type: cross Abstract: Vulnerability disclosure volumes now far exceed organizational assessment capacity, yet three adjacent research communities (proof-of-concept generation, vulnerability prioritization, and detection rule engineering) operate largely in isolation.
