What is JackPotting? - You make the ATM give you a lot of cash (like a Slot Machine)

Thieves install malicious software and/or hardware at ATMs that forces the machines to spit out huge volumes of cash 


The Secret Service alert explains that the attackers typically use an endoscope — a slender, flexible instrument traditionally used in medicine to give physicians a look inside the human body — to locate the internal portion of the cash machine where they can attach a cord that allows them to sync their laptop with the ATM’s computer.
