Keri Crane is an advisory technical product manager with Jack Henry & Associates. She focuses on card fraud management and the analysis of emerging payment trends. BIN attacks happen when fraudsters take the first six digits of a card and use a software to generate the remaining digits. Crane: “It is important that merchants check the CVV code and carry out 3D secure authentication, as well as do bot checking. From the issuer side, it is important to generate card numbers randomly rather than sequentially. This will go a long way,” she says.”]
