arXiv:2607. 19742v1 Announce Type: cross Abstract: Cyber Threat Intelligence (CTI) reports richly describe real-world attack processes, but their unstructured narratives cannot be directly used for automated attack-path reasoning.

Athena is a graph-based system that identifies affected libraries for software vulnerabilities by modeling vulnerability databases as a knowledge graph and applying knowledge graph completion. It integrates CVEs, libraries, CWE types, CPE products, and software ecosystems, then predicts missing affected libraries using link prediction and refines results with a fine‑tuned LLM that incorporates graph embeddings. Experiments on the VulLib dataset show Athena outperforms four state‑of‑the‑art baselines, achieving a 32% higher average F1 score and demonstrating that a smaller KGC backbone can surpass larger LLM‑only approaches.

The paper introduces AUTOSIGMA, an automated system that converts unstructured cyber threat intelligence reports into Sigma detection rules. It enriches input data with a structured knowledge base, matches it against existing Sigma rule repositories, and uses a large language model as a judge to validate the generated rules. Experiments on real-world APT reports and security blogs show that AUTOSIGMA outperforms other methods in rule validity, relevancy, MITRE ATT&CK coverage, and robustness to input quality.
