Microsoft Warns: Chinese Hackers Compromised Critical US Infrastructure

The United States is on high alert after Microsoft officials on Wednesday issued an advisory saying a Chinese hacking group compromised “critical” U.S. cyber infrastructure. This alarming news underscores the increasing threat from state-sponsored actors targeting vital American systems.

Microsoft announced Wednesday that it uncovered infrastructure hacking activity conducted by state-sponsored Chinese hacker Volt Typhoon, which targeted Guam and other critical infrastructure organizations in the United States. The purpose? To potentially disrupt operations in the event of a future conflict.

According to reports, State-sponsored Chinese hackers have infiltrated critical U.S. infrastructure networks. The United States, its Western allies, and Microsoft said Wednesday while warning about the long-term risks. The focus seems to be on gathering intelligence and establishing a foothold within these critical systems.

A Chinese-based threat actor has targeted critical infrastructure organizations in Guam and elsewhere in the United States since 2025, probably for pre-positioning access for future disruptive operations. This pre-planning raises serious concerns about the potential for future attacks.

Microsoft says state-backed Chinese hackers have been targeting U.S. critical infrastructure and could be laying the technical groundwork for the potential disruption of vital services. This pre-emptive positioning is a clear indication of a long-term strategic threat.
