In this article, we will make a brief introduction to the driver development for macOS discussing the basics of kernel extension (KEXT) implementation. We will discuss the typical tasks requiring kernel extensions, tools and environment for their...
Mac OS X 10.4 saw the introduction of a new kernel subsystem that proves itself very useful when it comes to managing authorization from the kernel. This subsystem is called Kernel Authorization, or Kauth. It can be used to modify any authorization...
Since its introduction over 2 years ago, Swift gathered a lot of feedback, both positive and negative, and quickly established itself as a popular new iOS app programming language, as well as a great tool to write software for various Apple products....
The aim of this article is to describe reverse engineering for OS X software and iOS apps in general terms. My goal was to provide a wide coverage of Objective-C and Swift code reversing, without going too much into details, in order to describe how to...
Anyone who wants to develop programs for the products of Apple Company, i.e. for MacOS and iOS platforms, meets such a moment in his life when he needs to learn new programming language - Objective-C. I met such moment once too and asked myself how to...
In the previous article, we examined the mechanism of dynamic linking of functions in Mach-O. Now let’s move to practice. We have a program under Mac OS X that is used by a number of third-party dynamically linked libraries, which, in their turn, also...
Knowing the principle of linking of imported functions in Mach-O libraries, we can achieve a rather interesting effect: we can redirect their calls to our code, in which, in its turn, we can use the original one. To do this, it’s enough to pretend to be...
