The administration of U.S. President Joe Biden is hunting for malicious computer code it believes China has hidden deep inside the networks controlling power grids, communications systems and water supplies that feed military bases in the United States and around the world, according to U.S. military, intelligence and national security officials.
The discovery of the malware has raised fears that Chinese hackers, probably working for the People’s Liberation Army, have inserted code designed to disrupt U.S. military operations in the event of a conflict, including if Beijing moves against Taiwan in coming years.
The malware, one congressional official said, was essentially "a ticking time bomb” that could give China the power to interrupt or slow U.S. military deployments or resupply operations by cutting off power, water and communications to military bases. But its impact could be far broader, because that same infrastructure often supplies the houses and businesses of ordinary Americans, according to U.S. officials.
