The Treasury Department has announced sanctions in connection with a massive Chinese hack of American telecommunications companies and a breach of its own computer network.

The Treasury Department’s Office of Foreign Assets Control (OFAC) announced on Friday that it had sanctioned a China-based cybersecurity company, known as Sichuan Juxinhe Network Technology, which it says is directly linked to the China-backed Salt Typhoon hacking group.

The State and Treasury Departments say Chinese cybersecurity vendor Sichuan Juxinhe is behind the hacks into numerous US telecommunications companies.

The Federal Communications Commission (FCC) has ordered U.S. telecommunications carriers to secure their networks following last year's Salt Typhoon security breaches.

The espionage hack of at least nine American telecommunication firms — including giants AT&T and Verizon — targeted the Trump campaign, FBI wiretaps and top State Department officials.

WASHINGTON (Reuters) - The U.S. Treasury department on Friday sanctioned Shanghai-based Yin Kechen and cybersecurity company Sichuan Juxinhe Network Technology Co., accusing both of being involved in a series of hacks against American telecom companies.

The Biden administration on Friday announced sanctions on two Chinese entities accused of cyberattacks, including a firm it said is directly involved in the recent espionage campaign against US telecommunications firms and a hacker behind the recent breach of Treasury Department computers.
