A shadowy Chinese government-backed hacking group attacked critical U.S. networks, including in Guam, where it may have spied on the U.S. to gain an edge ahead of future crises, according to a Microsoft report and U.S. government advisory.
Microsoft said the organization, dubbed “Volt Typhoon,” has been active since 2021 to break into so-called “critical infrastructure” in Guam and other U.S. sites with the intent to secure long-term hidden access to networks and conduct espionage, according to a report published Wednesday. While targets spanned the U.S., Microsoft highlighted infiltration of national security-specific infrastructure in Guam, an important U.S. territory and military outpost in the Pacific that would likely serve as the front-line of U.S. defenses in the event of a conflict over Taiwan.
