A state-sponsored Chinese hacking group has been spying on a wide range of US critical infrastructure organisations, from telecommunications to transportation hubs, Western intelligence agencies and Microsoft MSFT.O said on Wednesday. China's foreign ministry on Thursday said the reports were a disinformation campaign initiated by the US.
The espionage has also targeted the US island territory of Guam, home to strategically important American military bases, Microsoft said in a report, adding that "mitigating this attack could be challenging."
