In this lecture, I will present an overview of the NFC technology, how it is being used and what industries can and will benefit from it most (hint – Retail, Fintech & IoT) – while focusing on its security aspects. We have seen an increase of 400% in the production of NFC enables devices in the last 3 years and an increase of ~300% of the number of connected IoT devices. The numbers are continually growing rapidly. After clarifying the uniqueness and special aspects of the NFC technology, we will take a deep dive into application security aspects of NFC based solutions such as duplicating tags, parameter tampering, sensitive information saved in plain text and more. The technological mechanisms of NFC create a unique threat landscape which I will discuss in detail presenting the risks, threats, and mitigations relevant to NFC. In addition, we will expose a customized PENETRATION TESTING METHODOLOGY for NFC based applications so you can tackle your next NFC based PT in an educated effective manner.
