A US government security official urged Americans to use encrypted messaging as major telecom companies struggle to evict Chinese hackers from their networks. The attack has been attributed to a Chinese hacking group called Salt Typhoon.
There have been reports since early October that Chinese government hackers penetrated the networks of telecoms and may have gained access to systems used for court-authorized wiretaps of communications networks. Impacted telcos reportedly include Verizon, AT&T, T-Mobile, and Lumen (also known as CenturyLink).
T-Mobile has said its own network wasn’t hacked but that it severed a connection it had to a different provider whose network was hacked. Lumen has said it has no evidence that customer data on its network was accessed.
