ATT&CK framework, cyber threat intelligence, unified cyber kill chain, pyramid of pain, data quality dimensions
In this paper we propose an approach for hunting adversarial tactics, techniques and procedures by leveraging information described in structured cyber threat intelligence models. We focused on the properties of timeliness and completeness of cyber threat intelligence indicators to drive the discovery of tactics, techniques and procedures placed highly on the so-called Pyramid of Pain.
We used the unit 42 playbooks dataset to evaluate the proposed approach and illustrate the limitations and opportunities of a systematic intelligence sharing process for high pain tactics, techniques and procedures discovery. We applied the Levenshtein Distance in order to present a metric between the attack vectors constructed from the kill chain phases for completeness and timeliness.
