At the USENIX Security Symposium here today, University of Florida researcher Nolen Scaife presented the results of a research project he undertook with Christian Peeters and Patrick Traynor to effectively detect some types of “skimmers”—maliciously placed devices designed to surreptitiously capture the magnetic stripe data and PIN codes of debit and credit cards as they are inserted into automated teller machines and point-of-sale systems. The researchers developed SkimReaper, a device that can sense when multiple read heads are present—a telltale sign of the presence of a skimmer.
