You probably have at least two smart cards in your pockets right now. Your credit card, and the SIM card in your cell phone. You might also have a CAC, metro card, or the contactless key to your hotel room. Many of these cards are based on the same basic standards and share a common command format, called APDU.
This talk will discuss and demonstrate how even in the absence of information about a given card, there are a series of ways to enumerate the contents and capabilities of a card, find exposed information, fuzz for input handling flaws, and exploit poor authentication and access control.
