Adversary groups are regularly confused with their initial operation or campaign. threat-actor-classification meta can be used to clarify the understanding of the threat-actor if also considered as operation, campaign or activity group.

Analysis of supply-chain attacks, particularly involving Trojanized packages, has revealed similarities between CoughingDown malware and post-compromise tools used in these incidents. Evidence such as consistent service creation and C2 domain overlap further supports the connection between EAGERBEE and CoughingDown.",
