When UNIX co-progenitor and super-smarty-pants Ken Ritchie was given a Turing Award, he provided a warning to those within ear shot. Admins and developers often find it satisfactory to review the source code of applications to determine maliciousness. And to a certain extent, this works out all right. Over time we have built a series of expectations of where to expect naughty code based on our experience. We have also chosen to trust other types of tools that we use during this process. We discriminate. But there's no reason that bad stuff *has* to be in the applications that we expect to find it in. Yes, the clever among us know that compilers can be bad. But we check the source of our compilers and find no bad stuff, and so we assume we are safe. We do, though, compile the compiler, don't we? Well, alright then some megalomaniac at Intel or somewhere far upstream decided to embed badness in the embedded distro compilation software. We can still look at the binary of com...
