Funny...I was just going to post this, but thanks for reminding me of the name. As I recall, it was a short story (I want to say I read it in Life, of all places), about a "hot shot" programmer who ignores another, older, programmer who wants to show him this cool new tech he's been working on. Suffice to say the hot-shot programmer gets seduced into selling the company secrets and, this is the part I remember most vividly, does it in a motel room, using a modem, and while he's waiting wanders down the hall to the coke machine.
He gets into hot water when the "secrets" turns out to be pictures of kids or something, and the older guy and the boss tell him that he's not only fired, but probably will have to sell the fancy car he bought to pay back the guys he was trying to sell the secrets to. Suffice to say, the way he's caught is that he didn't type the password in the "right" way, just like TFA (presumably...didn't pay to read it) mentions, and gets caught in a honey pot.
The weird thing is that I have never forgotten the idea of being identified by how you type, and every time I use the keyboard that story just flashes in and out, after all this time.
