"An ongoing Chinese hacking campaign known as Volt Typhoon has successfully gained access to numerous American companies in telecommunications, energy, water and other critical sectors, with 23 pipeline operators targeted, FBI Director Christopher Wray said"
"China is developing the "ability to physically wreak havoc on our critical infrastructure at a time of its choosing. Its plan is to land low blows against civilian infrastructure to try to induce panic."
I think this is actually just an elaborate Chinese marketing campaign to sell more radios and cheap survival gear.
