China's Persistent Cyber Threat to US Infrastructure and National Security

US officials are concerned that Chinese hackers may still have access to sensitive US computer networks they’ve targeted in recent months, including critical infrastructure in Guam and Taiwan. The Chinese government-backed hacking campaign is “unacceptable” because the hackers sought access to networks that might allow them to disrupt critical services in the future. The US and its allies are urging infrastructure operators to check their networks for compromise, while China denies the allegations and accuses the US of conducting hacking operations in China.
