How would they be instantly caught?

  Massive network traffic, extra power use, etc.

  because exfiltrating data is hard, and if all of your devices are doing it, it's only a matter of time someone notices. it's not going to be "instant", but the risk/reward ratio isn't good.

    I do agree getting that data out unnoticed is tricky. But something remotely activated/deactivated (magic packet) would be trivial. So it's not necessarily all your devices doing it all the time and that could make it very difficult to detect. If that limitation still makes it worth doing depends on what you need to achieve. The reward could be huge.

      Yes, but remote activation pretty much means targeted. I am absolutely convinced that there are backdoors in huawei devices, be it intentionally or through carelessness. There's news about backdoors in Cisco products at least once a year - completely accidentally obviously, since we are the good guys. However, the Chinese would be very careful about using them. Every time you do, you risk getting caught, because just in that moment someone on the target network could be running wireshark to debug some unrelated problem. And once you're caught you're done. You won't risk that to fetch some random HN user's browsing history to blackmail them.
