iOS 13.5

Radio proximity security attack targeting up to iOS 13.5 detailed by Ian Beer

Accomplished security researcher Ian Beer, known for releasing a host of iOS exploits used by modern jailbreak tools, dropped a bombshell on Twitter late Wednesday evening after sharing a detailed blog post about a jaw-dropping radio proximity exploit affecting up to and including iOS and iPadOS 13.5.

The blog post summary goes on to explain that the hacker can remotely trigger kernel memory corruption through the execution of arbitrary code. Furthermore, it can force affected iOS and iPadOS devices in radio proximity to reboot with no user interaction needed or put privacy at risk by breaching user data or utilizing cameras and microphones without the user’s knowledge.  Scary indeed…

Apple blocks downgrades to jailbreakable firmware by unsigning iOS & iPadOS 13.5

Apple this evening stopped signing iOS & iPadOS 13.5, a move on the Cupertino-based company’s behalf that essentially prevents iPhone and iPad users from installing this particular version of its firmware whether downgrading from a newer version of the mobile operating system or upgrading from an earlier version.

The move comes approximately one week after Apple released iOS & iPadOS 13.5.1 to the general public specifically with the intention of patching the 0-day kernel vulnerability that Pwn20wnd implemented into the unc0ver jailbreak to add support for iOS & iPadOS 13.5, the latest version of Apple’s mobile operating system at the time.

Last chance to downgrade to iOS 13.5 and jailbreak with unc0ver

Apple on Monday released iOS and iPadOS 13.5.1 to the general public for the sole purpose of patching the new exploit in the unc0ver v5.0.0+ jailbreak tool, and as you might come to expect, Apple will soon unsign the jailbreakable iOS 13.5 firmware.

It usually takes the Cupertino-based company a week or two after a new firmware release before it stops signing an older version of iOS or iPadOS, but in recent memory, just one week has been a lot more common. By doing this, Apple can leave its user base with no option of downgrading or upgrading back to iOS or iPadOS 13.5, effectively preventing users from jailbreaking.

Pwn20wnd offers workaround for software update bug in unc0ver v5.0.0-5.0.1

Apple today released iOS & iPadOS 13.5.1 specifically to patch the new kernel exploit that Pwn20wnd incorporated into the unc0ver v5.0.0+ jailbreak tool to support iOS & iPadOS 13.5, making it now more important than ever to avoid updating your device to the latest available firmware if you care whatsoever about being able to customize your handset in an bevy of different ways that otherwise wouldn’t be possible out of the box.

As pointed out this evening by unc0ver lead developer Pwn20wnd, however, it seems that unc0ver versions 5.0.0 and 5.0.1 exhibit a bug in which the option in the unc0ver app for disabling automatic software updates will behave opposite to how users have it configured:

Downgrades from iOS 13.5 halted as Apple stops signing iOS 13.4.1

Apple is no longer signing iOS or iPadOS 13.4.1 as of this evening, a move that prevents iPhone and iPad users from downgrading from the iOS and iPadOS 13.5 software updates that the Cupertino-based tech giant released to the general public just last week.

Downgrading iOS device firmware isn’t a common necessity, but it can be necessary if or when Apple releases a software update that introduces bugs or instability to its devices. This isn’t a particularly common thing to happen, but it did transpire last October when iOS 13.2 was found to be ‘too aggressive’ with backgrounding restrictions, compelling many users to downgrade until a software update could be released to fix the issue.

Zebra v1.1.9 released to fix frustrating error message on latest unc0ver

If you excitedly jailbroke iOS 13.5 yesterday using the new unc0ver v5.0.0 jailbreak and then went to install the Zebra package manager as an alternative to the preinstalled Cydia package manager, then you probably found yourself plagued with error messages claiming “Operation Not Permitted” before your very eyes.

Evidently, you weren’t alone if you experienced this issue. Many Zebra users reported this problem after jailbreaking with the new unc0ver on Saturday, and now Zebra has been updated to version 1.1.9 with an official fix so that users can use the package manager error-free on their newly pwned handsets.
