Can you trust the compiler?
Not really. You do have to trust a compiler, but you don’t have to know beforehand which one you must trust. If you have the source code for compiler T, you can test it against compiler A. Basically, you still have to have at least one executable compiler you trust.
What happened to Ken Thompson?

It is the most widely used encoding on the World Wide Web.
Why is it not safe to trust code or even a compiler !) That you did not totally create yourself?
You can’t trust code that you did not totally create yourself… No amount of source-level verification or scrutiny will protect you from using untrusted code. And the attack vector doesn’t have to be the C compiler… any program-handling program (assembler, loader, microcode etc.)

Is the Ken Thompson hack still a threat?
Ken Thompson Hack (1984) Ken Thompson outlined a method for corrupting a compiler binary (and other compiled software, like a login script on a *nix system) in 1984. I was curious to know if modern compilation has addressed this security flaw or not.
When did Ken Thompson invent the compiler hack?
Ken Thompson outlined a method for corrupting a compiler binary (and other compiled software, like a login script on a *nix system) in 1984.
Is the compiler hack still a threat to Linux?
Nowadays, hardware is much more compatible and compilers therefore have a much smaller role in the day-to-day operation of a system. A compromised compiler is not the most scary scenario anymore – rootkits and a compromised BIOS are even harder to detect and get rid of.
Why was the C compiler hack so scary?
This hack has to be understood in context. It was published at a time and in a culture where Unix running on all kinds of different hardware was the dominant system. What made the attack so scary was that the C compiler was the central piece of software for these systems.
