KeenLab demonstrates iOS 11.3.1 jailbreak at InfiltrateCon 2018

Renowned security researchers have been developing private iOS 11 jailbreaks for quite some time now. Here’s yet another iOS 11.3 jailbreak that KeenLab demonstrated today.

iOS 11.3.1 jailbreak achieved by KeenLab

Hackers Liang Chen and Marco Grassi of Tencent KeenLab demonstrated iOS 11.3.1 jailbreak at InfiltrateCon 2018 a few hours back.

Both team members also demonstrated the inner working of the iOS jailbreak chain at the hacking conference.

Just like their previous jailbreaks, the latest jailbreak, too, comes with Cydia.

Liang Chen also showed off an iPhone X running Cydia on iOS 11.3.1 firmware on Twitter.

Will KeenLab release a public jailbreak? 

If KeenLab’s previous exploits are something to go by, this jailbreak will not see a public release. All things considered, this does indicate how vulnerable iOS 11.3 really is now that we two jailbreak tools for it.

For the uninitiated, Qixun Zhao of Qihoo 360 Vulcan Team also achieved a jailbreak on iOS 11.3 a couple of days back.

Again, it is not impossible for KeenLab to make an exploit or vulnerability public. The reason behind this is that hacking teams usually rely on private vulnerabilities and bugs.

If some other team discovers the same bug and discloses it to Apple, it essentially becomes useless.


This can and does result in a public release. As a case in point, Team Pangu released many jailbreak tools back in the day once Apple patched the underlying vulnerabilities.

As far as updating goes, stay on iOS 11.2.6 or below as any iOS 11.3 exploit will also likely be compatible with older versions.

If you are unsure about which version is worth an update, you can always leave a comment below.
