I'm still not sure I believe this. I heard about this long ago, and understood it to be a thought experiment, if an ominous one. And I was shocked to hear reports that it was "real" and "live" in the C compiler (which one? GNU?) But I'm not sure if I believe this; could Ken still be pulling our leg at this point? What is the nature of the malware or backdoor? How is it accessed? What does it do? Does it grant root privileges to an unprivileged user? Does it execute untrusted code? Does it open a socket for a RAT? Does it work under Windows? MacOS? Android? Is Ken keeping mum about the nature and capabilities of the backdoor so he still has leverage? If this is true, it's a security concern about the size of Intel's IME, don't you think?
