Microsoft: State-sponsored Chinese hackers target U.S. communications

Microsoft says state-backed Chinese hackers have been targeting U.S. critical infrastructure. The company says the hackers could be laying the technical groundwork for the potential disruption of communications between the U.S. and Asia in future crises. The targets include Guam, where the U.S. has a major military presence. Hostile activity in cyberspace — from espionage to the advanced positioning malware for potential future attacks — has become a hallmark of modern geopolitical rivalry.
