| Well, *actually*... As Dennis Ritchie has pointed out, some early
| versions of logind and cc contained code to implement a backdoor in
| the login. cc had been altered to recognize logind's source and
| introduce the backdoor. cc had also been altered to recognize it's
| *own* non-backdoored source and introduce the recognizer backdoors.
Actually, that was Ken Thompson. Please see "Reflections on Trusting Trust",
ACM Society Classic of the Month, Sept 1995. (Originally printed in
_Communication of the ACM_, Vol. 27, No. 8, August 1984, pp. 761-763.)
Finally, one of the True Paranoids speaks. :-)
It was never determined if Ken was telling a story, or if he actually
did perpetrate the hack. He does credit a since-gone-missing Air Force
memo as inspiring the idea.
