“There are attack vectors in all these standalone or hole-in-the-wall ATMs,” Jack warned, noting that many ATMs are protected by a master key that can be bought for $10.78 on hundreds of web sites. ”With this master key, I can walk up to a secluded ATM and have access to USB [and] SD/CF slots. In some cases, opening and inserting my USB key was faster than installing a skimmer,” he said.
May you expalain how to use USB in ATM?
I never see an ATM that can use USB.
Maybe there is a USB port within one of the locked compartments. Not sure though since I've never seen one.
