China-affiliated hackers infiltrated Verizon's telephone network and targeted prominent US political figures, including Kamala Harris, Donald Trump, and JD Vance.
The hacks are part of an intelligence-gathering campaign by a Chinese government-affiliated hacking group known as "Salt Typhoon".
The same group also attacked US broadband providers, potentially accessing information from systems used for court-authorized wiretapping requests.
The FBI and the Cybersecurity and Infrastructure Security Agency confirmed that the hack was carried out by actors affiliated with China.
