CompSci Colloquium: "Designing Robust Defenses for Modern Payment Systems"

Designing Robust Defenses for Modern Payment Systems

ABSTRACT: Credit, debit, and prepaid cards have dominated the payment landscape for decades, empowering the economy. The deployment of new technologies is slow, expensive, and difficult to adopt. This talk discusses new ways of identifying and protecting against real threats to existing payment systems. First, we will explore the types of skimmers and how they acquire sensitive card data, and then examine a use case, gas pumps, where skimming remains prevalent and how the tools available to consumers for detecting these devices also fail. After characterizing real skimmers, we use their properties to design the Skim Reaper, the first external skimmer detection system. By using attackers' own technology against them, these attacks can effectively and inexpensively be reduced.
