I was checking PDP's hack on citrix and i stumble across a coke machine hack. Well, i am not sure if this is an old exploit or if it is still working as of today or it is patched. However, i could not replicate this hack on a vending machine here. Maybe it is of a different model or different system or different chipset. Whatever it is, this is a cool one. Simple yet effective.
