IG Learner Walkthrough

This is a hands-on Android security lab describing tools, setup, and eight practical lessons for assessing the 'Learner' app: extracting and decompiling APKs, reading logs to find secrets, exploiting insecure file permissions, analyzing URI handlers, performing SSL/TLS MITM and bypassing certificate pinning, examining client-side encryption weaknesses, querying exposed content providers, and crafting malicious intents. The guide is educational and focuses on reverse engineering and app re-packaging techniques to demonstrate common mobile vulnerabilities and defensive considerations.
