This semester I got a Microsoft fitness band for a project. The original goal was not hard: understand the client communication. So I decided to pwn it for fun. Thanks to my friends in OSIRIS lab who supported me a lot, thank you mates. And also my mentor, mongo, inspired me so much and taught me a lot, thanks man!
So first, we need to figure out some of the basic behaviours of the fitness band, like how it upgrades firmware, uploads user status etc. Luckily the client is just a windows binary, so we don’t need to set up environment to reverse the Android app or IOS app. The Windows client is available here. Since the client was written in c#, we can use tools like ILSpy, JustDecompile, dnSpy and dotPeek to debug & decompile it easily!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
