For issuing banks, ensuring proper HSM validation of ARQC cryptograms remains the strongest defense. Implement robust monitoring for duplicate ATC values and unusual transaction patterns. The primary draw is malicious: fraud
Some EMV implementations use predictable "unpredictable numbers" in cryptogram generation, which can be exploited to compromise chip and PIN cards. The ARQC is calculated over the supplied data, and if properly implemented, it allows the ATM or POS to verify that the card is alive, present, and engaged in the transaction. However, the reality is very different when implementations fall short of specifications.
