I’ve been reading about how the telco networks of AT&T and Verizon have been hacked in what is being claimed as an attack from China, and authorities believe the hackers still have access to these networks. Here, is what I found interesting:

The move is in reaction to law enforcement backdoors in the public telephone network - including AT&T, Verizon and T-Mobile - being hijacked by Salt Typhoon; a cyberattack group believed to be operated by the Chinese government. source

Emphasis added. Officials are advising that we all use communications that is end-to-end encrypted, which ironically is the last thing law enforcement officials want as they have been demanding backdoors to encrypted networks for years.
