Yes it does, but not quite in the same way. For example, I believe that in days of yore some attackers managed to insert a back door into some DEC OS by breaking into the coding environment (I don't recall the details, does anyone else?).

<http://www.acm.org/classics/sep95/> describes how the inventors of Unix inserted a backdoor into the Unix login program. It's well worth reading. However, there is no indication that this trojan horse ever shipped to customers.
Well, try logging in as "ken", and I think the password was "nih" :-) (At least when I was starting my Unix career, it was still common to have logins "ken" and "dmr" around as a courtesy, though eventually computer security changed that practice.) Also, mixing up DEC and Unix has long tradition; back in 1979, there was an article in one of the Oakland or SF papers about "Hackers at Berkeley" cracking security on "the Unix, a computer made by DEC", which was really about abusing answerback on VT100s.
