AdversaryGraph public intelligence page

This page is part of Threat Matrix, the public browser workspace for the main AdversaryGraph platform. Use it for ATT&CK pivots, actor and technique context, similarity leads, detection coverage review, and analyst-ready investigation paths.

Validation disclaimer: TTP overlap, actor similarity, generated summaries, and coverage findings are investigation leads, not attribution proof or operational validation without analyst review.

Cleaver

Aliases: Cleaver, TG-2889, Threat Group 2889

[Cleaver](https://attack.mitre.org/groups/G0003) is a threat group that has been attributed to Iranian actors and is responsible for activity tracked as Operation Cleaver. (Citation: Cylance Cleaver) Strong circumstantial evidence suggests Cleaver is linked to Threat Group 2889 (TG-2889). (Citation: Dell Threat Group 2889)
