The iOS vulnerability that made it possible for users and hackers to jailbreak the iPhone in iOS 12.4 has just been completely eliminated with the latest update of Apple’s operating system. The company has just applied, this time correctly, the patch prepared in previous versions of its operating system to correct the vulnerability exploited by Pwn20wnd to eliminate the restrictions of the signature phones.
The security warning that accompanies the release of iOS 12.4.1 states that a kernel vulnerability is corrected that allows malicious applications to execute a code to grant different privileges of different levels to the “attacker” In other words, this iOS update 12 cover the “hole” used by hackers to jailbreak the iPhone in the latest version of iOS released a few days ago.
Interestingly, this vulnerability was already corrected with the release of iOS 12.3 but the arrival of iOS 12.4 eliminated this solution and reopened the doors wide open to jailbreak. Fans of iPhone modification immediately realized this error and began publishing their different tools to release the device, allowing users to do all kinds of things that are not normally possible, including the installation of unauthorized applications.
Jailbreak on iPhone
Today it is quite absurd to jailbreak Apple phones because, over time, iOS has been incorporating many of those tools that once we could only find in Cydia, one of the main app stores that allowed us to add tools unique to the iPhone as long as we had the jailbreak.
Today exploiting these vulnerabilities only weaken the protections that prevent an application from reading or modifying the data of another application that is, increasing possible risks to users. In 2016, for example, a malicious attack known as Pegasus used a text message that exploited a vulnerability, through jailbreak, to install malware on iOS devices developed by the government of the United Arab Emirates.
If you want to continue using jailbreak, under your decision and with the consequent risks to which you are exposed, you must continue on iOS 12.4.
I can confirm the exploit was patched in iOS 12.4.1 – – Stay on iOS 12.4!

However, we always recommend you to always update to the latest version of an operating system to protect yourself from possible external attacks that may cause you even more headache without even being aware of it.
