alt Hacker NewsGoogle has started publishing "binary transparency", this would help detect unusual software updates, while other methods (including AI) would help detect normal backdoors.
Basically in the AI age, the difference between a vulnerability and a backdoor diminishes..
I may be naive, but how would binary transparency be effective if they ship an update to disable that on a target device? As long as there is a need for legitimate automatic software updates, the possibility of pwn updates will always exist. Plus a myriad of layers, keys and other stuff they could use NSOs to 'seize' and inhibit knowledge of their effort from leaking, or cleverly hide in plain sight. And someday, with the help and speed of AI.
