Suspected Chinese Cyber Operations Targeted U.S. and Belgian Government Networks
Suspected Chinese hackers were linked to multiple intrusions into Western government systems, including the exploitation of the SolarWinds software supply-chain compromise to access the U.S. National Finance Center, a payroll agency serving several federal departments, according to Reuters sources. In a separate case, Belgian prosecutors opened an investigation into an alleged breach of the country's intelligence service, with reports indicating Chinese state-linked actors may have accessed an external email server used for communications with public prosecutors, police, ministries, and other institutions.
The incidents add to a broader pattern of state-backed cyber espionage focused on sensitive government data and communications infrastructure. The U.S. case highlighted how attackers used a trusted software update channel to reach federal networks, while the Belgian probe underscored concerns that third-party systems connected to intelligence and law-enforcement bodies can become high-value entry points for foreign surveillance operations.
