What’s inside of Apple’s new AirTag? There was already an iFixIt teardown (which I swear was missing a few items that are there now), but of course was curious to see what sort of protection was enabled. Notably the nRF chip used is likely vulnerable to a known bypass of security as well. With that in mind, I set out to see how we could dump some data from this thing – the good news is you can access a lot of interesting stuff (including the SPI flash) right from the backside, which requires you to simply pop the first plastic cover off. This is super-easy to do without damaging anything. Going further than that is tricky to keep it all intact.
If you want to jump right to the answers, check out my AirTag-RE repo on github where I list the known test points that will be of interest. You can also see my twitter thread where I started the teardown:Continue reading Apple AirTag Teardown & Test Point Mapping
