T-Mobile Stopped China With Scissors, GTA 6 Leaked, Walmart Takes Apple Pay, Zombie Credit Cards
T-Mobile stopped a Chinese state-sponsored hacking campaign by physically cutting a network cable with a pair of scissors. The GTA 6 leaker appears to actually have a playable build of the unreleased game. Walmart is finally accepting Apple Pay after a 12-year cold war. And university researchers just figured out how to bring expired Visa credit cards back from the dead. This week, John and Logan break down seven stories covering nation-state cyberattacks, game leaks, payment security, and a piece of Apple history that involves the CIA. Stories in this episode: T-Mobile stopped China with scissors. In late 2024, the Salt Typhoon campaign was tearing through American telecommunications companies. T-Mobile spotted routing traffic coming from a device that was powered off and traced it back to compromised equipment at another telecom in Chicago. CSO Jeff Simon and three other employees drove to a data center, located the connection, and cut it with a pair of scissors. T-Mobile kept the severed cable and it's now on display at headquarters. GTA 6 leaker apparently has the game. A person calling themselves CyberLeek has been dropping unreleased GTA 6 footage. The clip that changed everything shows the protagonist landing a plane, walking to a wall, and using individual bullet holes to spell the word "LEEK." You cannot coincidentally shoot LEEK into a wall during someone else's demo. Take-Two has subpoenaed Microsoft and Discord. Rockstar now has to stop somebody who can play the unreleased game from telling the internet how it ends. Zombie credit cards. Researchers at UMass Amherst discovered that the expiration date on a Visa card is not cryptographically protected in Visa's Kernel 3 implementation. Two Android phones and Wi-Fi are enough to relay a real card's authentication while quietly changing the expiration date in transit. They demonstrated a $100 contactless transaction on an expired Visa. Destroy your old cards. Walmart finally accepts Apple Pay. Starting August 24th, Walmart and Sam's Club begin rolling out Tap to Pay in select stores. Walmart spent 12 years fighting NFC payments, backed the disastrous CurrentC consortium in 2011, and stuck with QR codes long after the rest of the country moved on. CurrentC is dead. Apple Pay survived. Plus the LockBit ransomware group listing U.S. Bank as a victim (which U.S. Bank strongly disputes and attributes to a fourth-party event), the newly reported story of how the CIA may have accidentally saved Steve Jobs' NeXT with a 20,000-computer order and set the stage for the iPhone, and a new subdomain enumeration tool called crt.name that indexes more than five billion hostnames through a free API.
