IOS 12.4 Reintroduces A Pactched Bug; Jailbreaking Becomes A Thing Again

IOS 12.4 Reintroduces A Pactched Bug; Jailbreaking Becomes A Thing Again

A security researcher going by the name of Pwn20wnd released a public jailbreak that exploits the reintroduced bug, and marks one of the first free and open jailbreaks for iOS devices in years; it's been a while since the last time we heard about an iPhone jailbreak, though they tend to be kept quiet to keep Apple's software security police from patching them.

Fortunately, Apple appears to be working on a patch, according to Motherboard.

In the meantime, users running iOS 12.4 who have zero interest in jailbreaking their iPhones should take extra care downloading apps.

Apple recently announced to pay up to $1 million to security researchers for finding flaws and vulnerabilities as part of its bug bounty programme.

San Francisco: Apple has reportedly unpatched a bug in the latest iOS update 12.4 that it had fixed in the earlier iOS 12.3 update - leaving its most up-to-date iPhones vulnerable to hacking risk.

Tonight we showed it. "As long as we do that, we can kind of stay on his good side". "We're going to have to do that". By putting pressure on defense and getting to the rim, that in turn opened up 3-pointers for the team's shooters.


However, according to Pwn20wnd, who developed the jailbreak, the flaw could also be used to "make a flawless spyware".

This was used by iOS hacker and researcher Pwn20wnd who created and published a new version of its jailbreaking tool, unc0ver v3.5.0, "with iOS 12.4 support for A7-A11 devices" on August 18. This means that up-to-date iPhones cannot only be jailbroken, but hacked as well.

Security experts have warned to be careful what apps they download with this jailbreak. The other reason is that each iOS release has made it more hard to find exploits that would give hackers entry to jailbreak those mobile devices. For example, he said, a malicious app could include an exploit for this bug that allows it to escape the usual iOS sandbox-a mechanism that prevents apps from reaching data of other apps or the system-and steal user data...

This security flaw made it possible for maliciously crafted apps to execute arbitrary code using system privileges on iPhone 5s and later, iPad Air and later, and iPod touch 6th generation.
