Google Introduces New Weather‑Based Threat Actor Taxonomy (Castle, Ion, Neptune, Relic, Comet)
What Happened — Google’s threat‑intelligence team announced a new naming system for state‑sponsored and cyber‑crime groups, using weather‑related prefixes (Castle, Ion, Neptune, Relic, Comet) paired with a second word that conveys motivation or origin. The schema replaces a patchwork of legacy identifiers (e.g., APT44, Sandworm) and aims to simplify mapping across industry taxonomies.
Why It Matters for Compliance & Audit Readiness
- Consistent threat‑actor naming feeds directly into vendor‑risk programs, enabling repeatable, auditable due‑diligence checks on third‑party threat exposure.
- A unified taxonomy reduces manual reconciliation effort, supporting continuous control monitoring and defensible SOC 2 evidence for the Vendor Management principle.
- Aligning internal threat feeds with Google’s schema helps maintain an up‑to‑date threat‑intel repository, a key input for risk assessments required by SOC 2 CC6.1 (Third‑Party Risk Management).
Who Is Affected — Enterprises that rely on external threat‑intel feeds, MSSPs, and any organization subject to SOC 2 vendor‑management controls across all sectors.
Recommended Actions
- Map Google’s new identifiers to your existing threat‑intel taxonomy and update any automated enrichment pipelines.
- Document the mapping process as part of your vendor‑risk evidence package for SOC 2 audits.
- Incorporate the refreshed taxonomy into continuous monitoring tools to ensure real‑time alerts remain audit‑ready.

Technical Notes
- No new vulnerability or exploit disclosed; the change is purely nomenclature‑focused.
- Google’s system pairs a “origin” word (e.g., Castle = China) with a contextual descriptor (e.g., Relic).
