## Summary

Jiska Classen (@naehrdine), a security researcher at the Secure Mobile Networking Lab at TU Darmstadt, discusses her work in reverse engineering wireless hardware, focusing on Broadcom Bluetooth chips and iOS devices. She details the creation of tools like Internal Blue and Frankenstein to patch and emulate Broadcom firmware, and explains how Frida and ToothPicker are used to fuzz and analyze the iOS Bluetooth daemon. The conversation also covers the reverse engineering of AirTags, including custom sound playback and privacy features, and the development of the AirGuard app for Android.
