First time accepted submitter JeffOwl writes "BBC is reporting that thieves are infecting ATMs with malware using USB sticks. The malware creates a backdoor that can be accessed at the front panel. The thieves are damaging the ATM to access a USB port then patching it back up to avoid notice. This indicates that the crew is highly familiar with the ATMs in question. Once the ATM is infected, the thieves use a 12 digit code to bring up the alternate interface. The thieves, not wanting their crew to go rogue, have built a challenge-response access control into their software and must call another member who can generate the response for them."
