Sort of reminds me of about 10+ years back when a couple of computer guys at a dog track wrote a program to identify all superfecta combos not played and print a ticket from an unused mutuel machine that was time-stamped before the race ran. I'm missing some details, but they got away with it for quite a while until one of their wives or GFs bragged about it.
Just goes to show that the old adage is correct - 3 people can keep a secret as long as 2 of them are dead.
