China-backed hackers have been infiltrating major U.S. critical infrastructure sectors for “at least five years,” according to an intelligence advisory released by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the NSA, and the FBI. The advisory highlights a shift in China’s cyber operations strategy, extending beyond traditional espionage to potentially gaining control of vital U.S. systems. The China-associated hacking group, Volt Typhoon, has targeted networks within critical sectors, including water, transportation, energy, and communications, by exploiting vulnerabilities in routers, firewalls, and VPNs and leveraging stolen administrator credentials. Volt Typhoon has maintained prolonged access to these systems, including control over surveillance camera systems, enabling them to potentially disrupt critical controls in energy and water facilities.
The advisory also raises international concerns over China’s cyber activities, as allied nations have also been targeted. This revelation comes amid heightened U.S. apprehensions that China might initiate destructive cyberattacks in the context of escalating tensions over Taiwan. Previous warnings from Microsoft and the U.S. government have indicated that Volt Typhoon has positioned itself to attack U.S. infrastructure, such as water utilities and ports. While recent efforts have prevented immediate access by the group, officials caution that Volt Typhoon remains determined to find alternative entry points.
The advisory emphasizes the vulnerabilities within U.S. critical infrastructure, including inadequate password management, security update protocols, and financial constraints that hinder security improvements. Legal obstacles have further impeded the government’s ability to mandate cybersecurity audits. In response to these threats, U.S. cyber defense agencies are urging infrastructure operators to strengthen their security postures. Recommended measures include applying software updates to all internet-facing systems, enabling multi-factor authentication, and activating activity logs to monitor for suspicious behavior.
