The Wi-Fi logs may or may not exist by default. To be honest, we are not sure why some devices have them and others do not. What we do know, is that the Wi-Fi log contains a ton of data that goes back far in history. It tracks both Wi-Fi and cellular and includes cleared connections and devices that the iPhone/Apple Watch were in range of. Some things we need to test – what if the user loses service or puts the device into airplane mode. What happens if there is a space issue on the device? From the initial tests, it seems as if the device will make space for the logs as they are not written to the user partition. Finally, does GrayKey and Cellebrite Premium provide access to these logs, or do you have to dump them yourself? Stay tuned for more research.
