Mobile (Android + iOS) — Offensive Testing Methodology

Quick Workflow

Static: pull the IPA/APK, decompile, dump resources/strings, identify endpoints
Dynamic: install on rooted/jailbroken device, hook with Frida, intercept TLS
Map exported attack surface: deep links, URL schemes, exported components
Storage / Keystore audit: where do secrets live, what protects them
API: every backend the app talks to is your scope — test like a web app

Lab Setup

Android

Rooted device or Genymotion / Android Studio AVD with userdebug build
Magisk for systemless root; LSPosed for hooks; Frida server matching device arch
Burp / Mitmproxy with system-trusted CA via Magisk module (MagiskTrustUserCerts)

iOS

Jailbroken device (palera1n / checkra1n / Dopamine depending on iOS version)
Frida + Objection + Filza + SSH via USB (iproxy 2222 22)
Burp CA installed via Settings → General → Device Management → Certificate Trust Settings

Static Analysis

Android

# Decode resources + smali
apktool d app.apk -o app

# Decompile to Java
jadx -d app_src app.apk

# Manifest review
xmllint --format app/AndroidManifest.xml | less
# Look for: android:exported="true", intent-filters, custom permissions, debuggable, allowBackup, networkSecurityConfig
