Your welcome but that’s the point he was making even if you build everything on your own. The backdoor would be in the compiler. So even if you built /bin/login for example he would just inject it at compile time when compiling your code. But then you asked I will just compile the compiler but you have to compile it at some point and he can inject the code back into the compiler at that point.
No worries , but i think I’m not being clear if you build it from scratch. how are you going you going to compile it ?
