Automating NFC Message Sending for Good and Evil by Nikki Benecke BrandtNear Field Communication (NFC) is an emerging proximity wireless technology used for triggering automatic interactions between mobile devices. In standard NFC usage, one message is sent per device contact, then the devices must be physically separated and brought together again. In this paper, we present a mechanism for automatically sending multiple messages without any need to physically decouple the devices. After an introduction to NFC and related security issues, we discuss the motivation for-and an implementation of-an automation framework for sending repeated NFC messages without any need for human interaction. Then we consider how such an automated mechanism can be used for both a denial of service attack and as a platform for fuzz testing. We present experimental evidence on the efficacy of automated NFC as a vector for achieving these goals. We conclude with suggestions for future work and provide some overall insights.
