A Structured Cyber Threat Intelligence Dataset Using STIX 2.1 Entities and MITRE ATT&CK Mappings
A manually constructed dataset of 150 English-language CTI reports, each represented as STIX 2.1 based graphs, provides a benchmark for CTI information extraction, knowledge-graph construction, incident analysis, and threat attribution and indicates that locally deployed LLMs can support human reviewers in identifying annotation inconsistencies, but expert validation remains essential.
