Security researchers at Antivirus firm Symantec claimed that hackers can exploit a weakness in Windows XP based ATMs, that allow them to withdraw cash simply by sending an SMS to compromised ATMs.

"What was interesting about this variant of Ploutus was that it allowed cybercriminals to simply send an SMS to the compromised ATM, then walk up and collect the dispensed cash. It may seem incredible, but this technique is being used in a number of places across the world at this time." researchers said.
