Android iPhone Risks and Solutions
summary
Claims exploited: 100% of a 2013 snapshot of top 100 Android apps had cracked versions and paid iPhone apps show ~50–56% crack rates; studies cited include IEEE 2012 and NCSU 2012. Tools and methods shown include IDA Pro, Hopper, dex2jar, otool, strings and Clutch to defeat encryption, plus method swizzling, JNI/assembly patches and jailbreak bypass by checking cydia.app. Practical build is an OWASP reverse engineering and binary protection project with recommendations like anti-debug + multi‑layer checksum guards to raise attacker cost.
