Microsoft shifts to a new threat actor naming taxonomy
2023-04-18 • Microsoft •
Microsoft announced a shift from its older Elements, Trees, Volcanoes, and DEV naming systems to a weather-themed threat actor taxonomy. The taxonomy is intended to make actor references clearer by grouping names around attribution or motivation and using adjectives to distinguish clusters with distinct TTPs, infrastructure, objectives, or patterns. Emerging or insufficiently attributed activity is tracked under temporary Storm designations until Microsoft has enough evidence about infrastructure, tooling, victimology, and motivation to merge or promote the cluster. The excerpt does not identify specific North Korea-linked actors or IOCs, but it explains how Microsoft’s future actor names and in-product intelligence references should be interpreted by defenders.
