TUPELO, Miss. (WTVA) - The Federal Bureau of Investigation is warning banks about a hacking threat that could cost millions.
According to cyber-security expert Brian Krebs, on Friday the FBI sent a private warning to banks that cybercriminals are preparing to carry out a fraud called ATM-cash out.
Federal agents say millions can be withdrawn in hours, by removing fraud controls on bank accounts.
"It looks like an organized effort to put cards out, put the numbers out, and at one time withdraw from the ATM," said Bobby Bean, an investigator with the Lee County Sheriff's Department.
Bean says the probable hack came through a phishing email at financial institutions.
"I think they are warning everybody about the ATM in case it happens," added Bean. "There's nothing you can do to stop it, just keep a watch on your account."
