About this track
Mobile app vulnerability classes, reverse engineering tools and techniques, and cryptographic implementation on iOS and Android.
The Mobile Application Security track collects 3 modules and 12 lessons into a single ordered path. Each module ends with a checkpoint quiz; passing the checkpoint unlocks the next module so you can track your progress without guessing whether the material has stuck.
You start with "Mobile Application Vulnerability Classes" and finish on "Mobile Cryptographic Implementation". The whole track sits inside the Mobile Security area of the curriculum, so the writing assumes the prerequisites listed above and skips ground that an earlier track has already covered.
What this track covers
- Mobile Application Vulnerability Classes — Explore the vulnerability classes unique to mobile platforms. From intent injection and URL scheme hijacking on Android and iOS, through WebView exploitation and insecure data storage, to IPC and component-level attacks that bridge the gap between apps and the operating system.
- Mobile Reverse Engineering Tools & Techniques — Go beyond the fundamentals of mobile analysis into the specific tools and workflows used by professional reverse engineers. Master jadx, apktool, and Ghidra for Android; class-dump, Hopper, and Mach-O analysis for iOS; advanced Frida scripting with Interceptor, Stalker, and bridge APIs; and the anti-analysis bypass techniques needed when apps fight back.
- Mobile Cryptographic Implementation — Master the cryptographic primitives that protect data on mobile devices. Explore iOS Keychain and Data Protection classes, Android KeyStore with TEE and StrongBox hardware backing, certificate pinning strategies for TLS, and the security models behind biometric authentication on both platforms.
How the track works
Every lesson is a short page with diagrams, runnable examples, and the kind of edge-case footnotes you usually only find in textbooks. Where it makes sense, the lesson is paired with a CPU simulation or a coding challenge so you can poke at the idea instead of just reading about it.
The lessons themselves are free to read with a free account. The 3 checkpoint quizzes that gate the next module are also free, as are the lesson IDE and CPU simulations. Optional 777-tier tools — the step-through debugger, decompiler, ROP gadget builder, heap visualiser, and exploit labs — sit alongside the lessons but are not required to follow the track from start to finish.
You can jump in at any point. Be Bitwise is built around a free forever curriculum, with no time limits and no expiring access. Pick the next lesson when you have an hour; come back when you do not.
