| contents | This paper studies the problem of Threat Actor (TA) naming convention inconsistency across leading Cyber Threat Intelligence (CTI) vendors. The current decentralized and proprietary nomenclature creates confusion and significant obstacles for researchers, including difficulties in integrating and correlating disparate CTI reports and TA profiles. This paper introduces HiP (Hesperus is Phosphorus, a reference to the classic question about the Morning and the Evening Star), a methodology for normalizing, integrating, and clustering TA names presumably corresponding to the same entity. Using HiP, we analyze a large dataset collected from 15 sources and spanning 13,371 CTI reports, 17 vendor taxonomies, 3,287 TA names, and 8 mappings between them. Our analysis of the resulting name graph provides insights on key features of the problem, such as the concentration of aliases on a relatively small subset of TAs, the evolution of this phenomenon over the years, and the factors that could explain TA name proliferation. We also report errors in the mappings and methodological pitfalls that contribute to make certain TA name clusters larger than they should be, including the use of temporary names for activity clusters, the existence of common tools and infrastructure, and overlapping operations. We conclude with a discussion on the inherent difficulties to adopt a TA naming standard, a quest fundamentally hampered by the need to share highly-sensitive telemetry that is private to each CTI vendor. |
