Second iOS 11.3.1 Exploit Dropped That Could Lead To Jailbreak [Ian Beer]

Just after a security researcher previewed his work of iOS 11.4 jailbreak with working Cydia, Ian Beer is back again with something that the members of, or a keen watcher of, the jailbreak community is looking for. This time talking about and publishing what he is calling empty_list, a proof-of-concept exploits for yet another iOS 11.3.1 kernel bug.

The Project Zero hero has been an instrumental and highly influential figure in the jailbreak community recently. Ian Beer has never actually put together a jailbreak that is used to liberate Apple’s iOS-powered devices.

Nevertheless, the employee of the project has been a finder of kernel-level bugs and the creator of a number of exploit proofs-of-concept – show how those bugs can be modified, then used and exploited. One of those projects was utilized in the current Electra tool which liberates iOS devices running iOS 11.1.2. His work will be embedded within the next-generation of Electra which will jailbreak iOS 11.3.1 on all devices.

CoolStar, the developer of Electra, had already previously taken to Twitter to suggest that the first upgrade to the platform offering support for iOS 11.3.1 will come as a developer-only release as it will require an active and paid Apple Developer account to function, but that is luckily more the case.

This latest bug, however, with no additional information provided about the limitations, could offer some light to that darkness. It is second exploit released by Ian Beer for iOS 11.3.1 and it’s the one that is being used which doesn’t require a special dev-only entitlement to trigger.

Given that it’s a kernel-level exploit, it offers compatibility with iOS 11.3.1, and the fact that it’s now public, and very possible that this could eventually be used in the imminent Electra jailbreak now although we will have to wait for CoolStar on confirmation.

Of course, it would be great to have something like this around the corner shed light on the whole situation by the teams and individuals involved. For now, we will have to speculate as best we can about how CoolStar and all others involved will proceed. Stay tuned for more updates!
