Caleb Turon and Matthew Hewlett hacked into an ATM machine in Winnipeg, Canada. The pair followed an old ATM operators manual found online to access the operator mode of the ATM machine. They printed off users’ transaction data, surcharge profits and the total cash held in the unit. The bank has already taken actions to prevent unauthorised access to its ATMs, which may have involved changing the default passwords on all of its ATM machines. The boys were not expecting the hack to work but when the machine asked for the administrator password and the pair gained access to the data.
