May 25, 2023 -EuroNews -Microsoft said the group of hackers, known as Volt Typhoon, tried to attack US military bases in Guam. China rejects the claims.
State-backed Chinese hackers have been targeting US critical infrastructure and could be laying the technical groundwork for the potential disruption of communications between the US and Asia during future crises, Microsoft has warned.
The targets include sites in Guam, where the US has a major military presence, the company added.
Microsoft said in a blog post on Wednesday that the state-sponsored group of hackers, which it calls Volt Typhoon, has been active since mid-2021.
It said organisations affected by the hacking – which seeks persistent access – are in the communications, manufacturing, utility, transportation, construction, maritime, information technology and education sectors.
Separately, the National Security Agency, the FBI, the Cybersecurity and Infrastructure Security Agency (CISA) and their counterparts from Australia, New Zealand, Canada and Britain – known as the Five Eyes – published a joint advisory sharing technical details on “the recently discovered cluster of activity”.
