I was able to social-engineer an operator a few times on TOPS-10 systems
back in the day to reset passwords, or mount disks. "Can you give me a
list of disks you have ready to mount?" - "blah blah blah" - "OK, mount
But then, one time, I was talking to an "operator" for a while before I
realized it was an ELIZA-like program that kept going back around in a
loop. Trying to be suave, I started it by asking how they were doing,
and got all sorts of weird responses.
At some point, realizing I was talking to a bot, I said: "I feel bad" -
and it replied something to the effect of "Can you explain why you feel
bad?". Typical ELIZA response ;)
Someone at that university had a sense of humor, that's for sure. Broke
into it anyway guessing passwords.
