Threat Group Cards: A Threat Actor Encyclopedia

APT group: Volt Typhoon

Names	Volt Typhoon (Microsoft) Vanguard Panda (CrowdStrike) Bronze Silhouette (SecureWorks) VOLTZITE (Dragos)
Country	China
Sponsor	State-sponsored
Motivation	Information theft and espionage
First seen	2020
Description	(Microsoft) Microsoft has uncovered stealthy and targeted malicious activity focused on post-compromise credential access and network system discovery aimed at critical infrastructure organizations in the United States. The attack is carried out by Volt Typhoon, a state-sponsored actor based in China that typically focuses on espionage and information gathering. Microsoft assesses with moderate confidence that this Volt Typhoon campaign is pursuing development of capabilities that could disrupt critical communications infrastructure between the United States and Asia region during future crises. Volt Typhoon has been active since mid-2021 and has targeted critical infrastructure organizations in Guam and elsewhere in the United States. In this campaign, the affected organizations span the communications, manufacturing, utility, transportation, construction, maritime, government, information technology, and education sectors. Observed behavior suggests that the threat actor intends to perform espionage and maintain access without being detected for as long as possible. Microsoft is choosing to highlight this Volt Typhoon activity at this time because of our significant concern around the potential for further impact to our customers. Although our visibility into these threats has given us the ability to deploy detections to our customers, the lack of visibility into other parts of the actor’s activity compelled us to drive broader community awareness and further investigations and protections across the security ecosystem.
Observed	Sectors: Construction, Education, Government, Industrial, IT, Maritime and Shipbuilding, Manufacturing, Telecommunications, Transportation, Utilities. Countries: Australia, India, UK, USA.
Tools used	FRP, Impacket, Living off the Land.
