Public Not Yet Taking China Cyber Threat Seriously, McMaster tells Congressional Field Hearing


Hoover Institution (Stanford, CA) — The federal government must warn the American public about the cyber threat posed by China, and the assembled experts of the Hoover Institution can help share the message, Senior Fellow H.R. McMaster told a panel of lawmakers on May 28. Alongside three cybersecurity experts, McMaster testified before three members of the US House Homeland Security Subcommittee on Cybersecurity and Infrastructure Protection on Wednesday at a special field hearing at the Hoover Institution’s offices on the Stanford University campus.

The hearing, entitled “Innovation Nation: Leveraging Technology to Secure Cyberspace and Streamline Compliance,” was planned for leading cyber and national security experts to brief lawmakers on how the private and public sectors can collaborate to improve US cybersecurity.In it, McMaster warned representatives Mark Green, Andrew Garbarino, and Eric Swalwell that the American public does not yet comprehend why Chinese-aligned hacking groups are intruding into American 5G networks or the phone accounts of presidential candidates.

“We haven’t really taken this to the American people to explain the gravity of it and say why China is in our systems,” McMaster said. “They are preparing for war—the Chinese Communist Party is preparing for war—in a number of ways.”In 2024, a hacking group dubbed “Salt Typhoon,” believed to be connected to China’s Ministry of State Security, infiltrated the networks of several leading wireless service providers and reportedly accessed the metadata of phones used by Donald Trump, JD Vance, and the staff of Kamala Harris during the presidential election campaign.

“They literally have a kill switch on the system right now,” Rep. Green said of the intrusion.McMaster told Green that Hoover has a number of programs that address cybersecurity, including the Technology Policy Accelerator, which explores the geopolitical implications of emerging technology, as well as Tech Track 2, which is designed to foster deeper cooperation between US government leaders, tech executives, and distinguished academics on urgent national security challenges.
