Over at least the past five years, the group has burrowed its way into various sets of civilian critical infrastructure around the nation, including ports and power grids. Officials have warned that the unit is surreptitiously embedding malware into infrastructure to enable future disruptions and trigger societal panic, likely to distract the American public if China moves to invade Taiwan.
