Google Overhauls Threat Actor Naming with Contextual Cryptonyms
Google Cloud's Threat Intelligence Group introduces a new two-word cryptonym system to standardize threat actor identification, providing immediate context on origin and potential motives.
Google Cloud's Threat Intelligence Group is implementing a significant overhaul to how it names and categorizes threat actors, moving away from disparate and often uninformative labels towards a standardized system of two-word cryptonyms. This initiative aims to enhance clarity, improve the speed of threat triage for security teams, and provide immediate context regarding a group's origin and potential motivations.
The new naming convention assigns a unique two-word cryptonym to each tracked actor. The first word is a unique identifier for the specific group, potentially retaining established terms from previous public reporting or being newly generated to avoid bias. The crucial second word provides immediate contextual information, with examples including 'CASTLE' for China-linked groups, 'ION' for Iran, 'NEPTUNE' for North Korea, 'RELIC' for Russia, and 'COMET' for cybercriminal operations. This structure offers a quick starting point for defenders without overstating the certainty of attribution.
This move addresses a long-standing challenge in the cybersecurity landscape: the proliferation of different names for the same threat actor or campaign across various research teams and public reports. Such fragmentation can lead to confusion, hinder effective communication, and slow down response efforts. By unifying naming conventions, Google Cloud seeks to reduce the cognitive load on security analysts and streamline threat intelligence sharing.
While the new system prioritizes clarity and context, Google emphasizes that it does not replace the rigorous work of attribution. Detailed analysis of attacker behavior, infrastructure, and targets remains essential to confidently link a group to a specific nation-state or criminal enterprise. The cryptonyms serve as an initial navigational aid, prompting further investigation rather than providing a definitive conclusion.
To ensure a smooth transition and maintain continuity, Google Cloud will continue to support legacy naming conventions within its threat intelligence platform. Older names will remain searchable, alongside mappings to MITRE ATT&CK techniques and aliases from other vendors. This backward compatibility is vital for incident response teams needing to reconcile historical data, monitoring rules, and existing case notes with the new nomenclature.
The rollout will begin with dozens of the most active threat groups, with a phased approach to cover more actors over time. Groups still under early investigation will retain 'UNC' (uncategorized) labels, reflecting a cautious approach to avoid prematurely solidifying tentative assessments. Security teams are advised to treat the new names as a guide, cross-referencing them with campaign-specific details like tools, victimology, and timing.
The broader benefit of this standardized approach is the creation of a common language that is easier to remember and understand, even for non-specialists. This can significantly improve the exchange of findings and help organizations prioritize their defensive efforts more effectively, especially in the face of rapidly evolving threat landscapes and sophisticated cybercriminal tactics.
This initiative by Google Cloud represents a significant step towards improving the efficiency and effectiveness of threat intelligence analysis and communication within the cybersecurity community.
