In 2010, the U.S. Department of Defense found thousands of its computer servers sending military network data to China — the result of code hidden in chips that handled the machines’ startup process.
In 2014, Intel Corp. discovered that an elite Chinese hacking group breached its network through a single server that downloaded malware from a supplier’s update site.
And in 2015, the Federal Bureau of Investigation warned multiple companies that Chinese operatives had concealed an extra chip loaded with backdoor code in one manufacturer’s servers.
