Just last year, SakuRα Development released kok3shi, a semi-untethered jailbreak tool for 64-bit iOS 9.3.2-9.3.5 devices. Over time, this particular jailbreak has received a bevy of tiny updates, but one launched just today appears to be particularly substantial.
If you’ve been following the developments surrounding iOS & iPadOS security research lately, then there’s no way you could have missed Brightiup’s CVE-2021-30955 kernel bug for iOS & iPadOS 15.0-15.1.1. Soon after the write-up, hackers and security researchers alike began making proof-of-concepts (PoCs), and later came the full-blown exploit from @b1n4r1b01.
Just over two weeks ago, security researcher @S0rryMyBad announced the discovery of an exploit for iOS 12.1.2 and below for pre-A12 devices, adding that he would release information about it after Apple patched it in a software update. Fortunately, that time has finally come.
Several hours after Apple released iOS 12.1.3 to the public on Tuesday, @S0rryMyBad made good on his promise by Tweeting a proof of concept screenshot of the bug that he had teased earlier in the month:
There was no shortage of exciting jailbreak-centric news this past week, but perhaps the most captivating tidbit of all was the announcement that tihmstar was tinkering with an exploit that could hack a subset of devices running iOS 11.2.6-11.4.1 – specifically those with headphone jacks.
It didn’t take long after the initial announcement for tihmstar to share that he had achieved tpf0, which permits arbitrary reads and writes to a device’s kernel memory. On the other hand, a pair of Tweets shared just weekend shed new light on the hacker’s intentions involving said exploit:
Just yesterday, we reported that hacking guru tihmstar was tinkering with an exploit targeting a subset of iOS 11.4 and 11.4.1 devices that sported headphone jacks. At the time, tihmstar only had kernel read access but was still working on kernel offsets and write access.
But those tides have changed as of Friday. tihmstar has taken to Twitter to announce that he achieved tfp0:
If you’ve been waiting patiently on iOS 11.4-11.4.1 for a jailbreak to surface, then you might be in for a treat. Hacking guru tihmstar appears to be tinkering with an exploit that supports these firmware versions, at least on specific devices.
A Tweet shared by tihmstar Tuesday evening denotes how the exploit in question supports iOS versions up to 11.4.1; on the other hand, it also relies on the headphone jack. This caveat means that some devices, like those powered by Apple’s A10 and A11 chips, aren’t supported:
While there’s been a lot of buzz in the jailbreak community lately concerning an iOS 11 jailbreak, some developers have been hard at work on alternative projects. One of those is G0blin, a jailbreak tool made by Sticktron that's aimed at A7-A9 devices running iOS 10.3.x.
Long-running speculation that Apple deliberately slows down older iPhones in software in order to supposedly push people into purchasing its latest models has been officially debunked and put to rest by Finnish computer benchmark developers Futuremark.
To help developers prepare for the arrival of iOS 11 and ARKit, Apple has made a demo application available to download and check out. If you have the prerequisites, it is actually very easy to get up and going with ARKit to try it out for yourself.
Repair experts over at iFixit tore apart Apple's new iPad with a brighter 9.7-inch screen. What they discovered doesn't come as surprise: the canonical iPad is basically an original four-year-old iPad Air with a more repairable screen and some new jewelry in the form of Touch ID, Apple Pay, Apple's homegrown third-generation 64-bit A9 chip with the embedded M9 motion coprocessor and other minor updates.
Unfortunately, the device's A9 processor is outfitted with two gigabytes of RAM. iPhone 6s's A9 chip has two gigabytes of RAM as well, just like iPad Air 2's A8X chip, so this may not be that big of a deal. On the other hand, it's a letdown considering iPhone 7 Plus is rocking three gigabytes of RAM.
Early Geekbench 3 benchmark of the Apple-designed A10 system-on-a-chip—which will be the next iPhone and iPad's engine—was posted Thursday by Dutch blog TechTastic.nl. Purported scores suggest the device may not be much speedier than the iPhone 6s and iPad Pro. The upcoming chip scored a tad more than last year’s A9 powering the iPhone 6s series and a little bit faster than the A9X in the iPad Pro.
On the other hand, the benchmarked A10 is almost certainly a prototype unit so final scores should be higher than is currently the case.
The first legitimate hardware teardown of Apple's new 4-inch smartphone, the iPhone SE, has been conducted by Chipworks. Apple just unveiled this new handset at its recent 'Let us loop you in' event alongside the new 9.7-inch iPad Pro.
The teardown finds that the iPhone SE is more than just a new generation of smaller iPhone from Apple, but that it's actually a very clever device that takes the best from the performance world and combines it with the economics of older devices. This allows Apple to provide a product at a cheaper cost, but with similar performance.
As the teardown reveals, the iPhone SE is actually a Frankenstein of iPhone 5s, 6, and 6s parts that all work together to create a powerful 6s-like performance experience in a smaller 4-inch package.
