When we are asked to perform a black-box security analysis on an iOS app, depending on the scope, we might only have access to the iOS app from the AppStore. But most of the time, the client would give us an IPA. In a black-box analysis, we won't get...
Read More...This is going to be a small article on the basics of working with Assembly Language. We won't go deep into building extensive programs in assembly. The main idea of this post is to clarify the workflow for creating an assembly program and some key...
Read More...Having a virtual machine running macOS opens up a lot of opportunities for learning. If you are into security, you can set up a VM for your security lab. Or if you want to learn networking or kernel debugging, it is also helpful to use a VM. The other...
Read More...Apple provides the Launch Services API so we can interact with different applications from our current process. We can define URL schemes for our apps, and when that URL is opened, our app gets launched. We can also specify which application to open...
Read More...If you've used the Swift Package Manager, you have interacted with its handy command-line tool. When creating command-line tools, we strive to provide an easy to use interface. One of the main characteristics of a good CLI tool is how it handles parameters...
