That's not proof, that's just an accusation. Huawei even offered up source access to customers as a way to prove that they didn't do that.

Not saying they don't do such things, but the evidence is lacking.

The first link depends on the second. The second requires some sort of sign up to read, but archive.is works as proxy https://archive.ph/Dov1N

The proof amounts to essentially one sentence spoken by an unnamed source

> U.S. officials said Huawei has built equipment that secretly preserves its ability to access networks through [lawful intercept interfaces]

but I understand that source confidentiality is useful so if WSJ trusts that, perhaps so should I. Not sure I'd then go so far as to independently say it has been "proven" when all that I truly know is that someone else believes someone else who has a commercial interest in saying this. It's probably true but that's not the same thing

I would trust a proven security research group's analysis and evidence of backdoors rather than CNN or WSJ that has a track record of lies and biases. They always cite government sources or experts without provided a single shred of evidence. I have read a lot of articles in relations to the so called "Chinese backdoor" and the "evidence" was either the equipment contains default root or admin passwords or the software has vulnerabilities. Last time I checked, most if not all vendors have default admin accounts and passwords so you can configure the device and change the initial password. Similarly I have not come across any network equipment software without security vulnerabilities. If you can refer me to an article with conclusive evidence please send me the link. This would be much appreciated.

You can't take the WSJ as proof of anything, let alone in regards to China.
