Reuters reports that the U.S. has been accused by the National Computer Network Emergency Response Technical Team/Coordination Centre of China of having spearheaded a cyberespionage attack campaign against Chinese tech companies since May 2023.
Intrusions believed to have been launched by a U.S. intelligence agency against a major intelligent energy and digital information firm and advanced materials design and research unit in China have prompted the large-scale exfiltration of trade secrets, according to CNCERT/CC.
Such allegations have yet to be acknowledged by the U.S. State Department. However, the development comes after China had been accused by the U.S. and its allies of deploying state-backed attacks to compromise trade secrets, prompting semiconductor and artificial intelligence export controls.
Attacks mostly associated with the U.S. were previously reported by CNCERT/CC to have been launched to compromise China's computers for later use in intrusions against Belarus, Russia, and Ukraine.
