The tech used here is the popular Flipper Zero, an ethical hacker’s swiss army knife, capable of all sorts of things such as WiFi attacks or emulating NFC tags. Now, 404 Media has found an underground trade where much shadier hackers sell extra software and patches for the Flipper Zero to unlock all manner of cars, including models popular in the U.S. The hackers say the tool can be used against Ford, Audi, Volkswagen, Subaru, Hyundai, Kia, and several other brands, including sometimes dozens of specific vehicle models, with no easy fix from car manufacturers.
Tbh the point isn’t really the tamagotchi, it’s all the other stuff it can do (like control your TV lmao, among other things.)
In fact most people immediately ditch the kneecapped OFW for something like momentum that lets you control the dolphin meter/your levels at will, and even use different asset packs or create your own animations (like me! I stole them from .gifs sure but I turned them into flipper anims!)
Now, there’s other stuff that can do everything the flipper can do, and better, but typically not all on the same device. It’s a universal remote for both IR and SubGhZ that can also read/write RFID and NFC, run marauder, use badUSB incl with JS, and expand its uses with GPIO to do things like trade pokemon to my GBC. It’s definitely not magic but it is pretty sweet.
