2024 United States telecommunications hack

On August 27, 2024, The Washington Post reported that at least two major internet service providers in the United States had been compromised by Chinese hackers. It was later reported that the hackers affected at least nine telecommunications firms in the U.S., including AT&T, Verizon, Lumen Technologies, and T-Mobile, and had also affected dozens of other countries. The hackers were able to access metadata of users' calls and text messages, including date and time stamps, source and destination IP addresses, and phone numbers from over a million users, including staff of the Kamala Harris 2024 presidential campaign, as well as phones belonging to Donald Trump and JD Vance. The hackers were also able to access wiretapping systems used to conduct court-authorized wiretapping. The attack was later attributed to the Salt Typhoon advanced persistent threat actor linked to China's Ministry of State Security (MSS).
