|That's similar but different in a couple of important ways. And it's not
|G.R. Emlin's, that's what reminded me of it.
|
|Here is the badge story as I heard it.
|
|Two MTS at Murray Hill were discussing their badges. It was routine to
|walk into the building, show the guard your badge, and keep walking.
|
|One guy said "They never look at those things! I'll bet I could paste a
|picture of a monkey on my badge, and he'd never notice it!". The other
|guy said "You're on!".
|
|So the first guy pastes a monkey picture on his badge. The second guy
|tips off the guard, and watches from inside the building.
|
|The first guy comes into the building and flashes his monkey badge to
|the guard. No reaction, so he keeps on walking. A few second later, the
|guard calls after him. "Hey, come back here! Let me see your badge." The
|guy knows he's in trouble, but he comes back and hands the guard his badge.
|
|The guard looks at the badge. He looks at the employee. He looks at the
|badge. He looks at the employee. He looks at the badge.
|
|Handing the badge back to the employee, he says "OK, you can go!"
Early side channel attack.
