HOWTO doc on hacking Coke vending machines by way of the drink selection buttons on the front display. Link (Thanks, Jason Sutton). Mirror one, Mirror two, and Google cache (Thanks, Dan, Jackson Baker and Scott M.)
Update:: Reader Chris Vincent says,
Just thought I’d point out that most of the content on those sites (including the Coke machine article) is verbatim from the Anarchist’s Cookbook, a legendary collaborative document that can be found all over the internet. Everything from social engineering to fun explosives to (obviously) Coke machine hacks can be found there.
Another interesting bit of information, this time about Pepsi machines (not from the cookbook, just something I found out about last week):
New Pepsi machines have a “code”, a special sequence in which you can push the buttons on the face of the machine, which causes the LED screen to report the number of cans sold and the total cash value. I’m not sure what that code is, and it may be configurable on a per-machine basis. I’m sure somebody out there can shed more light on it than me.
