WASHINGTON, October 10, 2026 — The United States has moved to disrupt online infrastructure allegedly used by Chinese-linked hackers to target critical infrastructure systems in America and other countries, intensifying concerns over cybersecurity and foreign digital threats.

The U.S. Department of Justice announced the seizure of seven internet domains allegedly used to support scanning and hacking activities against sensitive computer systems. Authorities linked the infrastructure to Integrity Technology Group, a Chinese information technology company previously associated by U.S. officials with the hacking group known as Flax Typhoon.

The operation follows an earlier disruption in September 2024 involving a botnet of more than 250,000 compromised consumer devices, according to the Justice Department.

Critical Infrastructure Security in Focus

The latest action highlights growing concerns about cyberattacks targeting essential services, including government networks, energy infrastructure and other systems that support everyday life.

Cybersecurity experts warn that identifying and disrupting malicious digital infrastructure is an important part of defending against sophisticated cyber threats. However, domain seizures alone do not eliminate every potential vulnerability or prevent attackers from rebuilding their operations elsewhere.

Integrity Technology Group did not respond to Reuters' request for comment. The Chinese Embassy in Washington rejected the allegations, saying China opposes hacking and disinformation.

The development underscores the continuing U.S.-China cybersecurity dispute and the importance of protecting critical infrastructure against digital espionage and cyber intrusions.
