Tihmstar achieves tfp0 exploit on iOS 11.4-11.4.1, jailbreaks could soon adopt support

Just yesterday, nosotros reported that hacking guru tihmstar was tinkering alongside an exploit targeting a subset of iOS 11.4 in addition to 11.4.1 devices that sported headphone jacks. At the time, tihmstar precisely had essence read access but was withal working on essence offsets in addition to write access.

But those tides cause got changed every bit of Friday. tihmstar has taken to Twitter to announce that he achieved tfp0:

Tfp0 is fundamentally a essence draw port that permits arbitrary reads in addition to writes to the device’s essence memory, in addition to this is especially fundamental to jailbreak development. As yous mightiness recall, the exploit Ian Beer released that facilitated the iOS 11 jailbreak was of the tfp0 variety.

We tin get together from tihmstar’s Tweet that the exploit is nearly complete, but to a greater extent than or less cleanup remains to preclude unwanted essence panics. What’s to a greater extent than is hacker in addition to unc0ver Pb developer Pwn20wnd replied to the Tweet alongside involvement inwards implementing tihmstar’s novel exploit inwards a hereafter unc0ver update.

There’s no official discussion yet concerning whether Electra volition adopt support.

While this is potentially adept intelligence for folks who mightiness live on waiting on iOS 11.4 or 11.4.1 for a jailbreak, it’s worth noting that tihmstar’s exploit precisely plant on handsets alongside a headphone jack. This caveat agency that to a greater extent than or less devices, similar those powered past times Apple’s A10 in addition to A11 chips, aren’t supported.

A12-powered devices don’t back upwards iOS 11 at all, excluding them from consideration entirely.

Those using iOS 12 instead of iOS 11.4 or 11.4.1 must maintain waiting for a populace jailbreak. While there’ve been several captivating iOS 12-centric exploit announcements inwards recent memory, at that topographic point is no official discussion of anyone working on an iOS 12 jailbreak every bit of yet.

As prominent members of the jailbreak community cause got expressed previously, anyone eager to jailbreak should remain on the lowest possible firmware instead of installing Apple’s frequent firmware updates. Updates tend to field the vulnerabilities hackers purpose to attain a working jailbreak, in addition to installing them makes exploiting your device to jailbreak it to a greater extent than challenging.

At the fourth dimension of this writing, Electra in addition to unc0ver maintain to live on the latest populace jailbreak tools available, in addition to both support iOS 11.0-11.4 beta 3.
