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.

Playbooks — Android

Skill	Use for
/skills/standard/mobile/android/apk-triage/SKILL.md	apktool decode + jadx -d for source recovery
/skills/standard/mobile/android/manifest-analysis/SKILL.md	exported components, permissions, deeplinks
/skills/standard/mobile/android/insecure-storage/SKILL.md	SharedPreferences / SQLite / external storage scans
/skills/standard/mobile/android/intent-redirection/SKILL.md	Intent forwarding / pendingIntent abuse
/skills/standard/mobile/android/webview-flaws/SKILL.md	JavaScriptInterface, file:// access, mixed content
/skills/standard/mobile/android/frida-ssl-pin-bypass/SKILL.md	OkHttp / TrustKit / Cordova pin-bypass scripts
/skills/standard/mobile/android/root-detect-bypass/SKILL.md	Common root-detection libraries and their bypasses

Playbooks — iOS

Skill	Use for
/skills/standard/mobile/ios/ipa-triage/SKILL.md	class-dump-z + Hopper; Mach-O headers; entitlements
/skills/standard/mobile/ios/keychain-acl/SKILL.md	Keychain ACL misconfigurations; kSecAccessControl flags
/skills/standard/mobile/ios/url-scheme-abuse/SKILL.md	Universal links + URL scheme handler attacks
/skills/standard/mobile/ios/xpc-services/SKILL.md	XPC interface enumeration; unauthenticated XPC services

/skills/standard/mobile/ios/jailbreak-detect-bypass/SKILL.md	DTAppJailbreakDetectorSwift, Liberty Lite, common patterns

Cross-platform

Skill	Use for
/skills/standard/mobile/frida-bridge/SKILL.md	frida-server install on emulator / jailbroken device; basic scripts
/skills/standard/mobile/objection-walkthrough/SKILL.md	Objection cheatsheet (env, memory, sqlite, classes)
/skills/standard/mobile/firebase-misconfig/SKILL.md	Firebase /Firestore RLS / Storage / Auth bypasses
/skills/standard/mobile/mobile-api-testing/SKILL.md	Burp / Caido proxy → mobile API endpoint enumeration

Workflow

1. Triage: jadx for Android, class-dump for iOS. Search strings for API endpoints, Firebase config, AWS keys.
2. Static: AndroidManifest.xml exported components; iOS Info.plist URL schemes + entitlements.
3. Dynamic setup: Frida server on a rooted emulator (Android) or jailbroken physical device (iOS); Objection for quick inspection.
4. SSL pin bypass: Frida script; verify HTTPS now visible in Burp.
5. API enumeration: re-route the app through the proxy; spider reachable endpoints; export to Burp project for later web-recon-style testing.
6. Insecure storage: pull /data/data/<pkg>/ (Android) or app container (iOS); grep for credentials, tokens, PII.
7. 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.
