At Def Con 25, the world’s longest running and largest underground hacking conference, Hacker Max Bazaliy of the Fried Apple Team has demonstrated a jailbreak for the Apple Watch 3 running watchOS 3. While the Apple Watch has been on the market for more than a couple of years now, a jailbreak has never been demonstrated publicly for it before.
The presentation by hacker Bazaliy during the conference suggests that a jailbroken Apple Watch will easily provide one with access to sensitive data like their health data, call records, emails, messages, calendars, GPS location, photos, and more. While unclear, it does look like the jailbreak gives SSH access to the Apple Watch thereby allowing the possibility of remotely accessing its system files and modifying them.
Disappointingly, it’s unlikely that Bazaliy will be making his Apple Watch jailbreak public. At this point, its also unclear if the jailbreak will also work with watchOS 4 or not.
With the limited amount of horsepower that the Apple Watch internals pack, a jailbroken watch is unlikely going to be of much use. Due to the same reason, chances of Cydia and other jailbreak tweaks being ported to watchOS 3 are pretty slim. If this jailbreak does get released to the public, do expect at least some basic tweaks to be available for the Apple Watch.
