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 …

In recent years, we have been working on devices with a focus on security and audits of banking transactions in physical systems, trying to create tools that help improve payments systems in banking terminals and accesses; developing cards with various technologies such as magnetic stripes and NFC, which are: HunterCat, HunterCat NFC, and Magspoof. On …
Existe una serie de protocolos y tecnologías alrededor del internet de las cosas como el bluetooth y WiFi que son de las más usadas actualmente y podemos encontrar en la mayoría de nuestras computadoras y smartphone. Pero también hay otras tecnologías que no son tan reconocidas o que están surgiendo como lo son LoRa o …
