Luca Todesco releases browser-based exploit for Pangu 9.3.3 jailbreak without certificate

Joaquim Barbosa ∙ December 8, 2016

Noted iOS security researcher and hacker Luca Todesco has just released a WebKit-based loader for the Pangu 9.3.3 jailbreak. This impressive browser exploit is reminiscent of the original JailbreakMe exploits on iOS 1 and iOS 4, after which it is named.

All that is required for the technique to work is to follow a URL in mobile Safari, press a button, lock your device and wait for the respring.

Whilst this development is testament to Todesco's hacking skills and has alleviated one major problem with the current 9.3.3 jailbreak: its reliance on developer certificates for the loader app, there is bound to be some confusion over what this tool actually does, and what it means for the jailbreak community. This post aims to bring some clarity to the topic.

How to fix TinyUmbrella v9.3.4 crashing on launch

Joaquim Barbosa ∙ Updated April 8, 2017

Many jailbreakers will be familiar with the program TinyUmbrella, which has traditionally been one of the best ways to save SHSH blobs for their iOS devices onto their Macs for safekeeping. What SHSH blobs are, their function, and how to save them is outside the scope of this article, (I will put something together soon on this), but suffice to say that saving these blobs is of some importance to many jailbreakers and that TinyUmbrella has been the go-to application for doing so for a long while.

Whilst the application was updated as recently as August by its creator Semaphore, many Mac users (myself included) have noted that the new version, 9.3.4, gives an error on launch and cannot be used at all. This guide will walk you through the fix to get your umbrella back up again on Mac, so you can carry on wishfully saving those blobs.

Limitless: the curious case of the Cydia fork project

Joaquim Barbosa ∙ December 6, 2016

John Coates, the creator of the popular patching platform Flex and a well-respected developer in the jailbreak community, announced this week the first public releases of a new endeavour called Limitless. Currently at Beta 6, this ambitious open project aims to bring newer features to Cydia's traditional functionality by freeing it from some of the constraints which the stalwart package installer faces, for example, version compatibility reaching through every iOS back to iOS 2.0.

How to enable AirDrop file transfers between unsupported Macs and over Ethernet

Joaquim Barbosa ∙ December 5, 2016

The AirDrop file transfer protocol, introduced with Mac OS X Lion and iOS 7, is a fast and convenient way to transfer files between Apple devices. The current version of the service is interoperable between iOS and macOS, but requires both Bluetooth and Wi-Fi to be active in order to work. It also requires Mac OS X Yosemite or newer and a hardware model from 2012 or later.

However, the version of AirDrop that shipped as standard with OS X between 10.7 (Lion) and 10.9 (Mavericks), whilst unable to send files to iOS devices, works without Bluetooth and on Mac models going back as far as 2008. Luckily, alongside the newer version, this legacy mode is still included on all Mac models to date, and as this guide will show, can be modified to have an even broader functionality.

How to hide specific mounted volumes from your Mac’s desktop

Joaquim Barbosa ∙ Updated December 8, 2022

We've already covered how to completely prevent partitions from mounting under macOS, but sometimes you want a partition mounted and ready to use but still want the benefit of it not cluttering up your desktop. For example, many people want their Time Machine partition constantly mounted and backing up throughout the day but don't need it to be visible at all.

Finder's preferences allow for hiding all volumes from the desktop but offer no control on a volume-by-volume basis. Therefore, we'll show you how to use the Terminal to hide mounted volumes on a case-by-case basis.

How to extend Quick Look preview functionality on your Mac

Joaquim Barbosa ∙ November 29, 2016

If you're not familiar with the Quick Look feature on macOS, try selecting a picture, folder, or text document on your computer and pressing the space bar. The rich preview that pops up is Quick Look working its magic. Apple introduced Quick Look in Mac OS X 10.5 Leopard and it has since gained support for many more file types natively, such as Microsoft Office and Adobe Suite documents.

I use it daily and it has become an automatic part of my workflow, a natural response to wanting to inspect a file without waiting for a program to launch and without leaving off what I'm doing.

However, the problem that Quick Look faces is support. It requires a plugin for each file type it can preview, and out-of-the-box only a handful are supplied. More obscure file types are neglected, and display only a blank pane with the file icon, name, size, and date modified. In this guide, I will detail how to add plugins to Quick Look for a richer and more useful preview experience.

Five ways to make the most of a file manager on jailbroken iOS

Joaquim Barbosa ∙ Updated December 5, 2016

The vast majority of non-developers who jailbreak do it for the tweaks, and use Cydia almost exclusively to find, maintain, and update them.

However, jailbreaking your device brings much more than the ability to install tweaks; its real power lies in granting unfettered access to the filesystem, which allows you to make almost any change you like.

In this article, I’ll go through five of the most interesting and ubiquitous uses for file managers on iOS.

How to prevent partitions from mounting when you boot up, log in, or connect drives to your Mac

Joaquim Barbosa ∙ Updated October 17, 2018

With the exception of partitions in unreadable formats and certain hidden partitions such as EFI and Recovery HD, the default behaviour of macOS is to mount all partitions of a drive on boot-up, login, or on connecting an external drive.

Whilst this behaviour is useful for the novice or for those connecting a single USB stick to copy some files, it can become unwieldy and even annoying if you have many multi-partitioned drives attached to your Mac.

For example, my desktop Hackintosh has three internal drives, each with at least two partitions, and one of these drives is not even needed when booted under macOS – it is for Windows 10 and Linux. Add to this a couple of external hard drives with partitions for storage, OS installers and Time Machine backups for other computers, and your desktop and Finder sidebar can begin to look a real mess. It also takes time for the drives to mount on every boot and unmount on sleep or shutdown.

This guide will detail how to ensure only the drives of your choosing mount automatically, leaving the rest unmounted within macOS.
