Banks warned about ATM hackers

Banks are being warned that hackers are changing controls on bank cash machines and making huge withdrawals from people's bank accounts.

The United States Secret Service says the hackers are able to get around caps on ATM withdrawals.

That allows them to take out more money than customers have in their bank accounts.

Small and medium-sized banks are said to be the most vulnerable.
