Researchers Revive Expired Credit Cards for Unauthorized Payments
Researchers reveal that expired contactless credit cards can be exploited for unauthorized payments. EMV protocol vulnerabilities are highlighted.
Researchers from the University of Massachusetts Amherst have discovered a method to extract payments from certain expired contactless credit cards, as detailed at the USENIX Security 2026 conference. They devised an attack that makes expired cards appear valid to payment terminals, exploiting vulnerabilities in the EMV contactless protocol. This raises significant concerns about the integrity of contactless transactions, particularly with Visa cards.
