New PIN Verification Bypass Flaw Affects Visa Contactless Payments

Sep 07, 2020
Even as Visa issued a warning about a new JavaScript web skimmer known as Baka , cybersecurity researchers have uncovered an authentication flaw in the company's EMV enabled payment cards that permits cybercriminals to obtain funds and defraud cardholders as well as merchants illicitly. The research , published by a group of academics from the ETH Zurich, is a PIN bypass attack that allows the adversaries to leverage a victim's stolen or lost credit card for making high-value purchases without knowledge of the card's PIN, and even trick a point of sale (PoS) terminal into accepting an unauthentic offline card transaction. All modern contactless cards that make use of the Visa protocol, including Visa Credit, Visa Debit, Visa Electron, and V Pay cards, are affected by the security flaw, but the researchers posited it could apply to EMV protocols implemented by Discover and UnionPay as well. The loophole, however, doesn't impact Mastercard, American Express, and JC...

But there is a specified limits country-wise. Contactless payment cards are meant to have a limit of £20 per purchase in UK, using which shoppers can buy things by simply tapping their card on a scanner, without having to type in a PIN.

Protecting Your Software Supply Chain: Assessing the Risks Before Deployment

Feb 11, 2025Software Security / Threat Intelligence
Imagine you're considering a new car for your family. Before making a purchase, you evaluate its safety ratings, fuel efficiency, and reliability. You might even take it for a test drive to ensure it meets your needs. The same approach should be applied to software and hardware products before integrating them into an organization's environment. Just as you wouldn't buy a car without knowing its safety features, you shouldn't deploy software without understanding the risks it introduces. The Rising Threat of Supply Chain Attacks Cybercriminals have recognized that instead of attacking an organization head-on, they can infiltrate through the software supply chain—like slipping counterfeit parts into an assembly line. According to the 2024 Sonatype State of the Software Supply Chain report , attackers are infiltrating open-source ecosystems at an alarming rate, with over 512,847 malicious packages detected last year alone—a 156% increase from the previous year.
