A major cybersecurity breach linked to the Chinese government has compromised the networks of several prominent US broadband providers, including Verizon Communications (NYSE: VZ), AT&T (NYSE: T), and Lumen Technologies (NYSE: LUMN), according to an exclusive report from the Wall Street Journal.
This intrusion, discovered in recent weeks, potentially gave hackers access to sensitive information related to court-authorized network wiretapping requests, posing a significant national security risk.
A sophisticated Chinese hacking group known as Salt Typhoon carried out the attack, which experts believe persisted for months or longer. It appears to have primarily focused on intelligence gathering, allowing the hackers to collect vast amounts of internet traffic data from service providers serving millions of Americans and businesses of all sizes.

US government officials consider the breach historically significant and deeply concerning. Investigators continue to work to determine the full extent of the attack and whether hackers exfiltrated data. The intrusion may have also affected a small number of service providers outside the United States.
This incident adds to growing concerns about China’s multi-faceted espionage efforts, which include human intelligence, business investments, and sophisticated hacking operations. US officials have recently warned about Chinese attempts to infiltrate critical infrastructure networks, potentially positioning themselves for disruptive cyberattacks in the event of a major conflict.
The Salt Typhoon group, active since 2020, focuses on espionage and data theft, particularly targeting entities in North America and Southeast Asia. Other cybersecurity firms have identified this group under different names, such as GhostEmperor and FamousSparrow.
This breach follows recent US efforts to disrupt other China-linked hacking campaigns, including Flax Typhoon and Volt Typhoon, which targeted critical US infrastructure.
