Unc0ver team published a jailbreak for iOS 13.5

Last weekend, a team of information security experts and reverse engineers from Unc0ver published a new version of the jailbreak (5.0.0) for the latest versions of iOS. This tool works for almost any iPhone, even with the latest iOS 13.5 on board.

Unc0ver authors say it exploits a zero kernel vulnerability in the iOS kernel, while Apple experts are not aware about it. The vulnerability was discovered by one of the team members, who is known under the pseudonym Pwn20wnd.

Last weekend, the Unc0ver team, without any details, simply announced on Twitter that its jailbreak version 5.0.0 was ready.

#unc0ver v5.0.0 will be the first 0day jailbreak released since iOS 8! Every other jailbreak released since iOS 9 used 1day exploits that were either patched in the next beta version or the hardware. This will be a big milestone for jailbreaking”, — wrote Unc0ver team members in Twitter.

Immediately after the publication of the tweet, the Unc0ver website went offline, unable to cope with the number of visitors who wanted to download the jailbreak.

Pwn20wnd says that for the first time in five years, jailbreak is relevant even for the current, most recent version of the operating system. The last time a similar tool was released in 2014. The fact is that usually jailbreaks exploit old vulnerabilities in iOS and, accordingly, do not work with the current version of the operating system, where these “holes” are already fixed. As a result, owners of jailbroken devices often prefer just not to update the OS.

Interestingly, Pwn20wnd claims that using an unknown 0-day problem and jailbreak devices with it do not affect security in any way. Allegedly, this does not open the device for attacks. According to Pwn20wnd, Apple experts will release a patch for a new vulnerability in the next 2-3 weeks.

Jailbreak basically just adds exceptions to existing rules. It allows reading new jailbreak files and parts of the file system that do not contain user data”, — also said Unc0ver lead developer, known as Pwn20wnd.

Unc0ver developers write that they tested their jailbreak on iOS versions 11 to 13.5. Jailbreak does not work only for iOS versions from 12.3 to 12.3.2, and from 12.4.2 to 12.4.5.

Let me remind you that recently arrived so many exploits for iOS that the well-known vulnerability broker, Zerodium refuses to pay for them, at least in the next few months.
