Like a privacy based fully open source browser. Wouldnt it be more hackable because every one know the script and is a glopal privacy based gpay alternative possible ? What about targeted hacking is someone using closed source application more better off than someone with ooen source ?
That part is about backdoors, not zero days. However, even still backdoors may exist. Linux has libraries and other code, as well as code that hasn’t been checked well enough, than could contain backdoors. It’s less likely than Windows, but still possible.
I’ve heard from “reputable sources” (internet schizos) that every cpu since 2010 has been backdoored by the nsa. This can be exploited on any platform.
There’s the Intel management engine and the amd platform security processor. Both manage low level tasks like booting, and have access to network data. Amds psp is known to have unrestricted access to user memory.
There have been security vulnerabilities that would grant access to sensitive data exploiting both systems if not patched.
As for a backdoor, there’s no evidence but I wouldn’t be surprised. The NSA has programs to insert backdoors into consumer products and these seem like the perfect place to do it. But again, there’s no evidence either chip is part of these programs.
