There’ve been so many kernel exploit releases for the iOS platform as of late that our heads are still spinning, but that’s pleasant news if you’re a jailbreak aficionado, because it gives our respected jailbreak tool developers more resources to work with.

The latest kernel exploit reportedly comes by way of hacker PsychoTea, and it has been named machswap. The exploit appears to be viable on all A7-A9 devices running iOS 11.0-12.1.2, which could make it a worthwhile candidate for modern jailbreak tools such as Electra or unc0ver.

Prevent specific apps from accessing the internet over Wi-Fi with ConditionalWiFi4

Anthony Bouchard ∙ February 28, 2019

Your iPhone lets you prevent apps from accessing the internet over a cellular connection right out of the box, but the same can’t be said about Wi-Fi. On the other hand, those with jailbroken iOS 12 handsets can finally do something about that with the help of a jailbreak tweak called ConditionalWiFi4 by Andrew Wiik.

As you might’ve discerned already from the tweak’s name, ConditionalWiFi4 lets you choose which apps can access the internet over your iOS device’s Wi-Fi connection. Some examples where this might come in handy include:

IntelligentPass 2 lets you use your iPhone without a passcode in ‘low-risk’ areas

Anthony Bouchard ∙ February 27, 2019

Most people use passcodes to protect their handsets from unwanted users for privacy reasons. Although modern handsets incorporate some form of biometric authentication in place of the passcode, whether that’s Face ID or Touch ID, your device still uses a passcode as a backup for when either of those stops working.

But while your passcode can keep your handset’s data safe in high-risk areas, it’s also true that some places (such as your home) pose little or no risk. That’s why iOS developers Luke Muris and Geometric Software released a new jailbreak tweak dubbed IntelligentPass 2.

Luca Todesco has released a WebKit RCE exploit that works on iOS 12.1.4 and earlier

Anthony Bouchard ∙ February 22, 2019

Before the days of Electra and unc0ver dawned upon us, there was Yalu, an iOS 10-centric jailbreak too by the talented hacker Luca Todesco (@qwertoruiopz); but apart from a few teasers here and there, the jailbreak community hasn’t heard much him since the Yalu days – that is, until now.

In a bombshell Tweet shared this week, Todesco released what appears to be a WebKit-based exploit that allows remote code execution (RCE) in web browsers with JIT. What’s more is that the exploit was only just fixed three days ago, which means it should be viable on all versions of iOS up to Apple’s latest release – 12.1.4:

Just under two weeks ago, hacking guru tihmstar released v1ntex, a voucher_swap-like exploit for 4K devices that contributed to iOS 11.4.x support in both the Electra and unc0ver jailbreaks. But just this morning, tihmstar released another exploit dubbed v3ntex, which allegedly supports iOS 12 devices.

Tihmstar shared his exciting announcement via Twitter Monday morning with proof of the exploit, adding that he only tested his v3ntex exploit on an iPhone 6 running iOS 12.1.2 and that it could likely still do with some improvements:
