An advanced group of Chinese hackers taking aim at critical US infrastructure has been active for as long as half a decade, American and allied intelligence agencies said in a joint statement on Wednesday.
The US National Security Agency, US cyber watchdog CISA, the FBI and the Transportation Security Administration said that the group known as Volt Typhoon had quietly burrowed into the networks of aviation, rail, mass transit, highway, maritime, pipeline, water and sewage organizations.
