The jailbreak community in recent years has come to less, either because of the amount of private data that we enter in our device (credit cards thanks to Apple Pay) that we do not want anyone to access or because the functions that we liked the most are already available in the most recent versions of iOS.
But the community is still running and although the launch rate has decreased. We see the most recent proof in the latest tweet posted by Richard Zhu, a security researcher champion of the last Pwn2Own 2018 and for which he received $ 120.000 for vulnerabilities detected in Microsoft Edge and Firefox.

At the moment we do not know if Richard intends to officially launch this jailabreak, although based on his history, he may choose to sell that information to Apple to close the exploits that allow jailbreaking in iOS 11.4, exploits that are probably the The same ones that allow you to jailbreak iOS 11.3.1 of which we still do not have an expected release date, since Electra software has not yet been updated.
In the video that you have posted we can see a device with iOS 11.4 installed using the alternative Cydia application store, an application that as we can see cannot be deleted Pressing on the springboard icons to activate the function that allows us to remove or move applications offers a guarantee of their possible authenticity.
He then uses the Terminal application and writes various commands to show that he has access to the root of the system. For now and while we have more news about it, the only thing we can do is wait to see if the Electra software is updated to allow jailbreaking in iOS 11.3.1 or if on the contrary, Richard releases his own version, something that It seems very unlikely.
