Threat actor cluster
Definition
A named collection of observed activity linked by shared infrastructure, malware, and TTPs, without necessarily having confirmed the real-world identity of the operators. Cluster names (such as APT28 or Lazarus Group) are analytical constructs used by threat intelligence firms; different firms may use different names for what may be the same underlying group.
