Verizon and AT&T have secured an important victory in the fight against the hacking group Salt Typhoon, saying they have ousted the hackers from their networks.

Salt Typhoon is a Beijing-backed hacking group responsible for the ““worst telecom hack in our nation’s history — by far.” The group has compromised at least nine US telecoms companies, giving China the ability to read text messages and listen to phone calls.

“My hair’s on fire,” said Senator Mark R. Warner, chairman of the Senate Intelligence Committee. He went to say “the American people need to know” the gravity of the situation.

“This is an ongoing effort by China to infiltrate telecom systems around the world, to exfiltrate huge amounts of data,” he added.

While the spying has largely been restricted to persons of political interest, especially in the D.C. area, there’s virtually no limit to what messages or calls Salt Typhoon can access. To make matters worse, security experts have struggled to remove the group’s access and lock them out of the telecom networks.

The revelation has caused the FBI and CISA to recommend that all individuals use Signal, WhatsApp, or another end-to-end encrypted (E2EE) messaging platform for the time being. The hack has also sparked a furious dialog regarding the state of US telecom security and increased regulation, with the FCC essentially giving telecoms an ultimatum to fix their security issues or pay the price.

In the wake of news that Salt Typhoon compromised the ninth carrier, Verizon and AT&T delivered some good news. Both carriers have issued statements that they have successfully evicted Salt Typhoon from their networks.

“Immediately upon learning of this incident, Verizon took several key actions to protect its customers and its network, including partnering with federal law enforcement and national security agencies, industry partners, and private cybersecurity firms,” Vandana Venkatesh, Verizon’s chief general officer, said in a statement to TechCrunch. “After considerable work addressing this incident, we can report that Verizon has contained the activities associated with this particular incident.”

“We detect no activity by nation-state actors in our networks at this time,” AT&T said in a statement to Fortune. “Based on our current investigation of this attack, the People’s Republic of China targeted a small number of individuals of foreign intelligence interest. In the relatively few instances in which an individual’s information was impacted, we have complied with our notification obligations in cooperation with law enforcement.”

Hopefully the remaining seven telecoms are able to secure their networks soon.
