Over the past decade China’s hacking program has grown rapidly, to the point that in 2023 Christopher Wray, then FBI director, noted it was larger than that of every other major nation combined. China’s growing heft and sophistication has yielded success in three main areas.
The first is political espionage, linked primarily to the Ministry of State Security (mss), China’s foreign-intelligence service. Last year it emerged that one group of Chinese hackers, dubbed Salt Typhoon, had breached at least nine American phone companies, giving them access to the calls and messages of important officials. Ciaran Martin, who led Britain’s cyber-defense agency from 2016 to 2020, compares it to the revelations in 2013 by Edward Snowden, a government contractor, that American spy agencies were conducting cyber-espionage on a huge scale. China was “gaining vast access to the nation’s communications via a strategic spying operation of breathtaking audacity,” he says.
A second is in areas of little espionage value: hacking that lays the groundwork for sabotage in moments of crisis or war. These efforts are led by the People’s Liberation Army (PLA), China’s armed forces. In 2023 it became apparent that a PLA-linked hacking group known as Volt Typhoon had, over several years, burrowed into an extraordinary range of American critical infrastructure, from ports to factories to water-treatment plants, across the continental United States and in strategic American territories such as Guam.
All of that builds on a third type of hacking: the industrial-scale theft of intellectual property. In 2013 Mandiant, a cyber-threat intelligence firm, which is now part of Google, made waves when it exposed “apt1”, the label for a group of hackers linked to the PLA. apt1 was not focused on stealing political secrets or turning off power grids but on stealing blueprints, manufacturing processes and business plans from American firms. A year later, America’s government took the then unprecedented step of indicting five PLA hackers for this activity. Keith Alexander, a former head of the National Security Agency (NSA), America’s signals-intelligence service, described this as “the greatest transfer of wealth in history”.
