As a penetration tester who conducts extensive NowSecure Mobile App Pen Testing as a Service (PTaaS) assessments of Android and iOS apps, I’ve seen firsthand how often mobile apps fail to meet even basic security and privacy standards. I’ve encountered everything from unsecured sensitive data to apps collecting far more personal information than needed. These […]
Mobile apps have become indispensable to modern businesses, yet they present significant risks when not properly secured. NowSecure benchmark data indicates that 85% of apps found in public app stores have security flaws and 70% have the potential to leak personal data.

Welcome to the final blog post in our series about reverse engineering iOS system libraries with radare2. This time we’ll focus on finding cross-references across different libraries present in the dyld shared library cache (or DSC if you’re into acronyms). We’ll discuss various techniques to achieve this, each with its trade-offs between performance and amount […]
This is the second (and the shortest) installment of my blog series about reverse engineering iOS system libraries with radare2. We’ll introduce the concept of cross-references, why they’re important and the gist of them in r2. This blog post explores how to find cross-references from within a single library in the dyld shared library cache […]
Editor’s Note: Keeping up with ever-changing low-level operating system internals is no small task, especially when it comes to the iOS dyld cache, a key element that underpins how iOS apps interact with the OS layer. This post, by Francesco Tamagni, focuses on leveraging foundational pieces of radare2 to read and interpret the formats critical […]
