description: >
Use when the engagement target is an Android (APK / AAB) or iOS (IPA)
application. Covers static analysis (jadx, apktool, class-dump),
dynamic instrumentation via Frida and Objection, SSL-pinning bypass,
root/jailbreak detection bypass, deep-link / URL-scheme abuse,
exported-component attacks, IPC redirection, WebView vulnerabilities,
and biometric / Face ID / Touch ID bypass.

Mobile Operator Skill Catalog
Mobile is 40% of modern bug-bounty programs and is conspicuously absent
from Strix and XBOW commercial. This catalog covers both platforms with
shared Frida tooling for runtime work.

Workflow
- Triage: jadx for Android, class-dump for iOS. Search strings for
API endpoints, Firebase config, AWS keys.
- Static: AndroidManifest.xml exported components; iOS Info.plist
URL schemes + entitlements.
- Dynamic setup: Frida server on a rooted emulator (Android) or
jailbroken physical device (iOS); Objection for quick inspection.
- SSL pin bypass: Frida script; verify HTTPS now visible in Burp.
- API enumeration: re-route the app through the proxy; spider
reachable endpoints; export to Burp project for later web-recon-style
testing.
- Insecure storage: pull
/data/data/<pkg>/ (Android) or app
container (iOS); grep for credentials, tokens, PII.
- Component-level attacks: send crafted Intents (
adb shell am start ...) or URL-scheme payloads (xcrun simctl openurl ...).
Tools sandbox
- adb + emulator / physical device.
- jadx, apktool, dex2jar, jd-gui.
- class-dump, Hopper Disassembler, IDA Free (host-side).
- Frida-server (per device), frida (host), objection.
- mitmproxy / Burp Suite Community / Caido (PR #304 lands the LangChain
Caido tool bundle).
- MobSF (
mobsf Docker image) for automated triage when speed matters.
