Lumen, one of at least nine U.S. carriers reportedly compromised by the Salt Typhoon hackers, said the Chinese hacker group is no longer present on its network.
Lumen spokesperson Mark Molzen told TechCrunch that an independent forensic analysis confirmed that the company removed Chinese attackers from its network, adding that during the Salt Typhoon breach, “customer data was accessed. There is no evidence that it was,” he added.
Lumen's confirmation comes after US telecom giants AT&T and Verizon confirmed to TechCrunch that they also secured their networks following the breach. T-Mobile, another Salt Typhoon target, said last month that it had no evidence the hackers were still within its systems.
Both AT&T and Verizon said a small number of prominent customers had their communications accessed. U.S. officials said last week that a total of “fewer than 100” people were targeted, adding that most of them were senior U.S. officials and politicians based in Washington, D.C.
