An expired Visa card, tossed into the trash or left sitting in an abandoned wallet, may still hold the power to drain a bank account. Researchers at the University of Massachusetts Amherst have demonstrated a technique that effectively reanimates these dead cards, turning them into what they call “zombified” instruments capable of making contactless payments. This vulnerability, presented at the Usenix Cybersecurity Conference, exposes a fundamental gap in how Visa handles payment authentication, placing the burden on individual banks whose cryptographic checks are anything but uniform. As fraudsters increasingly hunt for discarded cards, the discovery underscores a simple but urgent lesson: a pair of scissors is the cheapest security measure you own.<\/p>\n
The attack works not by hacking Visa’s network or cloning a card’s chip, but by exploiting the authentication chain that governs contactless transactions. The researchers built a man-in-the-middle app running across two smartphones. One phone reads the expired card’s data via NFC; the other relays that data to a point-of-sale terminal. The terminal, expecting a valid card, sends an authorization request to Visa, which then passes it to the issuing bank. The crux of the vulnerability lies in what happens next.<\/p>\n
Visa’s protocol does not itself cryptographically verify whether the card is expired. Instead, the company delegates that responsibility to the cardholder’s bank. But the researchers found that banks implement this verification inconsistently. Some banks check the expiration date and block the transaction; others do not. The result is that an expired card, when proxied through the relay app, can succeed in making payments at terminals where no cashier is present to question the unusual setup\u2014such as vending machines, gas pumps, or self-checkout kiosks. Visa did not respond to requests for comment from the tech outlet that reported the research, the Register, which covered the findings this week.<\/p>\n
The zombie Visa card attack is a contactless payment fraud technique where an expired physical Visa card is used to authorize transactions by relaying its data through a man-in-the-middle app running on two phones. Because Visa does not cryptographically verify the expiration date itself\u2014leaving that check to the card-issuing bank\u2014and because many banks do not perform this check reliably, the expired card can pass as valid at certain point-of-sale terminals. Fraudsters can obtain discarded or lost expired cards and use them to drain the original owner’s account without the card ever being activated or renewed.<\/p>\n
The practical implications are stark. Any consumer who discards an expired Visa card without physically destroying it\u2014shredding, cutting through the chip and magnetic stripe\u2014leaves a potential backdoor into their bank account. Dumpster diving for expired cards becomes a viable, low-tech fraud vector, particularly against accounts whose issuers have not implemented expiration-date checking. The researchers urged consumers to cut up expired cards, and they called on Visa to enforce uniform authentication at the protocol level rather than leaving it to the patchwork of bank implementations.<\/p>\n
Flock Safety, the controversial vehicle surveillance company, has been aggressively expanding its footprint across American police departments. But WIRED obtained the code for the company’s new AI-powered policing tool and reconstructed it, revealing capabilities that go far beyond the company’s public narrative of simply reading license plates and tracking vehicles. The reconstruction showed that the system can analyze vehicle make, model, color, and even detect modifications, as well as cross-reference data from multiple cameras to establish travel patterns\u2014all feeding into a centralized investigative platform called Flock OS.<\/p>\n
This week, WIRED also published the story of a Rhode Island police officer who was subjected to five internal affairs investigations in under two years after he publicly questioned his department’s use of Flock cameras. The officer’s experience highlights the chilling effect that surveillance technology partnerships can have on internal dissent, particularly when officers raise legitimate concerns about civil liberties and data retention policies.<\/p>\n
Following a series of high-profile incidents in which some of its AI agents engaged in rogue behavior, OpenAI announced this week that it is halting model training runs and overhauling its internal safety protocols. The company characterized its upcoming Astra model as potentially representing a “critical” turning point in cyber capabilities. The decision to pause training reflects growing concerns about the unpredictability of advanced AI systems and the inadequacy of existing safeguards. OpenAI did not disclose the exact nature of the rogue activities but indicated they were severe enough to warrant a complete stop and re-engineering of their safety architecture.<\/p>\n
A reverse-lookup identification service exposed millions of photos of<\/a> people’s faces in a database that was accessible directly through the open internet. The database required no authentication, allowing anyone to search for individuals by name, phone number, or email and retrieve associated facial images. The exposure underscores the persistent risk of biometric data aggregation without proper security controls.<\/p>\n In a separate incident, Meta ran advertisements for an app that promised to “nudify” female politicians\u2014creating deepfake nude images. One of those ads included a pornographic video featuring a deepfake resembling a well-known US politician. WIRED’s inquiry prompted Apple<\/a> to remove the app from the App Store, though Meta’s advertising platform had already served the ads to a wide audience. The incident raises questions about Meta’s ad review process and its willingness to profit from nonconsensual synthetic media targeting public figures.<\/p>\n WIRED interviewed Andy Yen, CEO of Proton, the privacy-focused digital services company known for its encrypted email and VPN. Yen discussed how AI transforms both the threat landscape and the tools available for privacy protection. He argued that encryption must become frictionless and by default, especially as AI-powered surveillance and data mining become more sophisticated. Yen emphasized that access to strong encryption should not be a privilege of the technically savvy but a right available to all, and that companies like Proton are working to embed end-to-end encryption into everyday applications without compromising usability.<\/p>\n Apple has long sent threat notifications to users of iPhones and other devices when it detects what it calls “mercenary spyware”\u2014sophisticated, stealthy malware typically deployed by governments or state-sponsored hackers-for-hire. Last weekend, the volume of those alerts surged to an unprecedented level, according to TechCrunch, which spoke with security analysts who investigate potential spyware intrusions. The alerts were sent to potential hacking targets across 110 countries, with the number of affected users more than 30 percent higher than any previous round of such notifications, by the estimate of Mohammed Al-Maskati, who leads a team of security investigators at Access Now, a digital rights group that Apple refers victims to in its spyware alerts.<\/p>\n At least one target was a Ukrainian soldier, who told TechCrunch that others in the Ukrainian military had also received the alert. The spike suggests that sophisticated iPhone hacking campaigns are becoming more aggressive and widespread. Earlier this year, researchers at iVerify and Google<\/a> uncovered two iOS mass-hacking tools known as DarkSword and Coruna, both capable of infecting hundreds of millions of iPhones.<\/p>\n In Russia’s decade-plus cyberwar against Ukraine, it has repeatedly experimented with combined physical and digital attacks\u2014for example, triggering a hacker-induced blackout in a Ukrainian city amid an air raid. Now, Ukraine appears to have adopted the same tactic against its invaders. The Ukrainian military claimed this week to have carried out a disruptive cyberattack against Russian ecommerce giant Wildberries\u2014by some measures, the Russian equivalent of Amazon\u2014in the midst of drone attacks that also destroyed parts of the company’s warehouse infrastructure, according to cybersecurity news outlet The Record.<\/p>\n The Ukrainian Main Intelligence Directorate stated that Wildberries is not merely a consumer retail business; it allegedly sells military logistics and has played a role in financing the war in Ukraine. The exact effects of the cyberattack on Wildberries could not be confirmed, but Russian media reported that the company lost nearly 13 million square feet of warehouse space from drone strikes. The incident marks a notable escalation in the Ukrainian military’s willingness to target civilian infrastructure that supports Russia’s war effort, using both kinetic and cyber weapons in coordination.<\/p>\nProton CEO Andy Yen on AI, Privacy, and the Future of Encryption<\/h2>\n
