Google Security Researcher Shares Details on 'tfp0' iOS 11.1.2 Exploit That Could Lead to Future Jailbreak

by

Google security researcher Ian Beer, who works for the Project Zero team, last week highlighted an iOS 11.1.2 exploit called "tfp0," which he believes could be the basis for a future iOS 11.1.2 jailbreak.

Today, Beer released the exploit to the public. He says it should work on all iOS devices running iOS 11.1.2 or below, though he only personally tested iPhone 7, iPhone 6s, and a sixth-generation iPod touch.

What Beer released is not a full iOS 11 jailbreak as some had hoped, but what he's shared could potentially be used to create a jailbreak in the future.


iOS 11.1.2 is no longer the current version of iOS as Apple released iOS 11.2 on December 2, but Apple is still signing iOS 11.1.2 at this time. Apple will likely stop signing the older update in the near future, and its end could come sooner now that further information on the tfp0 exploit has been released.

Jailbreaking iOS devices has dwindled in popularity in recent years, which has led two major Cydia repositories to close. Both ModMy and ZodTTD/MacCiti, which provided apps, themes, tweaks, and more for jailbroken iOS devices, shut down in November. For the time being, iOS 11 continues to be the only major version of iOS that has not been jailbroken.

I am a big fan of jailbreaks. However, who really needs it anymore?

Since jailbreaking is a heck of a lot more than installing unapproved apps, I'd say the answer is "anyone who wants to customize their iOS experience."

When this question came up a week or two ago, here's what I posted:

For me, Jailbreaking has always been about additional customization. FlipControlCenter, for instance, lets you add different toggles to the pre-iOS 11 Control Center (so you could, for instance, have a Personal Hotspot toggle), have multiple scrollable groups of toggles, select which toggles could and could not be used from the lock screen, etc. It is far superior to the iOS 11 “solution” that Apple came up with.

FlipControlCenter, 3G Unrestrictor, Protect My Privacy, etc... These customizations are so far beyond what Apple allows... and are not available via side loading. As another poster said, it’s not really about apps.

However given the seriousness of some recent iOS security flaws, combined with the amount of sensitive info now accessible from my phone... it just doesn’t make sense to stay on an older, jailbreakable version of iOS. I have an original iPad mini which is still jailbroken - there are one or two non-approved apps I occasionally use. But that device is basically isolated from the rest of my Apple gear, and does not have any personal account apps (e.g. banking) on it.

A simple question (I'm not a lawyer):
Is publishing an exploit a white-collar crime when Google (competitor) employs this "research man"?

If you knew the definition then you would not be asking that question. IMO it’s a No.

I've been holding on to my 9.1 jailbreak for years now, wondering whether the few minor tweaks I have are really worth it. Then I discovered NGXPlay, which allows me to run *any* app in CarPlay, and it was like the good old days all over again. Being able to run Google Maps on my car screen is not just a vast improvement over Apple Maps, it's also a safety boon, since I've often been forced to resort to the iPhone's little screen while driving whenever Apple Maps (so often) screws something up. And like the good old days of jailbreak, along with the relief comes the usual disgust at Apple intentionally preventing simple things (like Google Maps) for the sake of stupid corporate competition.
