The Original Sin of Computing…that no one can fix
From LaurieWired.

What if we can't trust *ANY* software...even if you have the source code?
A perfect, self-replicating "sin" passed down for generations of compilers. Invisibly compromised in every program.
It sounds like a spy novel; only it actually happened.
Ken Thompson, creator of UNIX, theorized how Code Auditing won't save you. This is how it works...and why it's already in the wild.
