Type “fault injection” into a search bar and most of what comes back is conference slides and research papers, not store pages. People look this up to understand an attack before they ever buy hardware for it — and that’s exactly how we ended up building a tool for it ourselves. What is fault injection? …
Search “NFC emulator” and you’ll find two different things wearing the same name: a device that pretends to be a card, and a setup that forwards a real card’s session somewhere else. They solve different problems, and mixing them up is the fastest way to buy the wrong tool. What is an NFC emulator? An …
Garage doors, car remotes, weather stations, tire-pressure sensors — a whole layer of everyday wireless traffic lives below 1 GHz. WiFi and Bluetooth never touch it. The first time we pointed a stock Flipper Zero at a garage remote, it picked up the signal immediately. No shield, no extra hardware. What does Sub-GHz mean on …
A LoRa mesh like Meshtastic trusts whoever knows its channel password. That works fine among friends who all typed the same key into their radios. It works a lot less well the moment you ask what actually stops a stranger’s radio from doing the same thing. Our partner Eduardo Contreras — Wero to most of …
La semana en que DragonJAR llenó Medellín de gente que audita redes y desarma protocolos, pasó algo raro en nuestras estadísticas: los clics desde Colombia hacia electroniccats.com subieron de un puñado por semana a 40 en siete días. Alguien hasta buscó, tal cual, “donde se puede comprar”. Hasta hoy no teníamos una respuesta clara para …
Plate-reading cameras used to sit only at intersections, with a pole and a sign nobody missed. Now they show up bolted to a stop sign or tucked into a plain box on a fence, and you’d walk right past one without a second look. We spent August teaching Minino to notice them anyway. What is …
Not everyone doing fault injection wants a menu. A few of the researchers we’ve talked to at EMFI (electromagnetic fault injection) workshops eventually ask the same thing: once they understand the arm-and-pulse basics, how do they script a full parameter sweep instead of clicking through a terminal app? Our host tool for FaultyCat already answered …
Every workshop we’ve run starts the same slow way: someone’s laptop needs a virtual environment, a pip install, and a fix for USB permissions before they can even plug in a board. We built BomberCat to make NFC research approachable, and that installer friction worked against us. The newest release removes it. What is BomberCat? …
S Search “ESP32 Marauder” enough times and the misspellings start piling up — Marauader, Maurader, Marauda. That tells us a lot of people typing it have never held one. It’s not a single product, and we didn’t build it. It’s a piece of firmware, and we’ve flashed it onto enough of our own hardware to …
