New security updates overtake jailbreak advantages.

There are just so many privilege escalation fixes in the latest iOS 12.2 update. I finally removed the jailbreak from my primary device and updated.  Privilege escalation is when an unprivileged or user process (like an app from the app store or even a web page*) gets root or even kernel authority.  This is when bad turns to worse because it can do and see anything with any of the device’s data or sensors.   Since even the big trusted apps have been caught tracking or stealing data, I simply couldn’t leave myself unprotected any longer.

I’ll still of course keep a development device jailbroken on 12.1.2 for all of the reasons. It was a wonderful experience, only slightly beta. I appreciate all the hard work by everyone in the scene. I think i am going hate seeing the home bar again the most.

* web pages are often sandboxed separately from the app itself. Some might argue that a webpage would first have to escape the sandbox before it could escalate privileges. this is true, but i would respond that sandbox escape is just another form of privilege escalation, only one level down. There are also over a dozen webkit fixes in this update.

Cydia - Package management system for Jailbroken iOS.

A long time in the works, this is the first completely open source jailbreak to be released for an almost current version of iOS (11-12.1.2).  This is an interesting jailbreak.  It is semi-tethered, but unlike previous jailbreaks, this can at least be untethered from the device itself.  Using Cydia Impactor, you can side load the unc0ver app and install the jailbreak directly from the app.  it also allow the easy rejailbreak upon reboot or battery drain. Great work all around despite the remaining bugs and instability (it is still beta. Huge thanks to the efforts of @pwn20wnd and @sbingner).  To be honest, there are very few tweaks and apps that are ready for iOS 12, but i am excited to see the tradition of jailbreaking continue.  I have cydia again!  For the first tine since I closed down my own cydia repo.  C’mon developers, do you thing!

In truth, i never got it going on my phone, only my iPad.  I get a crash on my phone immediately after this dialogue comes up.  It took a few passes to get a picture (this one extracted from a screen record).  Not sure exactly what went wrong, but “Unexported kernel task port” is my best clue.  With my phone cashing as soon as it becomes untethered, i am never actually able to run Cydia. On my iPad, instead of rebooting, it resprings.  either way, it is very hard to read the final message.

Back to reality after another amazing DEFCON!

I met a pile of incredible people.  Bought some amazing toys (for science), some i’ve even got working.  Saw some talks and demos.  Talked to some of my heroes and listened to even more.  I saw Ladar Levison talk about epoxying your ports and adding thermite to your hard drives.  I played with the ECU of a fake car!  now i just have finish building the DarkNet Badge!  enjoy my pictures. The hat data is still being analyzed.  I’ll try to build something out of it eventually.

It’s finally fixed!

 

As you can see, it did turn out to be hardware, a GPU and CPU (ouch!).  The flash storage was not it, but I figured that out eventually. This has been an issue since October!  With many fixes attempted.  It was a bit of a blow to my pride eventually having to turn to Apple, but they stepped up and got it done with only mild frustration on my part.   Plus, they picked up the tab as my warranty is certainly expired.  There comes a time when you realize that a fix would require more parts then you had at hand.  I have been enjoying my functional desktop again, just in time for the new iMac Pro to make it obsolete.
