offensive-mobile

Mobile (Android + iOS) application penetration testing methodology. Covers static analysis (apktool/jadx for Android, class-dump/Hopper/IDA for iOS), dynamic instrumentation with Frida and Objection, SSL pinning bypass strategies, root/jailbreak detection bypass, deep-link / URL-scheme abuse, exported component attacks (Android activities, services, providers, receivers; iOS XPC, URL schemes, universal links), insecure data storage (SharedPrefs, KeyStore misuse, NSUserDefaults, Keychain ACL bypass), IPC / Intent redirection, WebView vulnerabilities (JavaScriptInterface, file:// access), Firebase/AWS/Azure misconfiguration leakage, mobile API testing, biometric/Face ID/Touch ID bypass, app-cloning and runtime patching, and mobile malware/RAT analysis primitives. Use for mobile pentest, bug bounty mobile triage, or app-store reconnaissance.

Content

72%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable, command-rich mobile pentest methodology that assumes Claude's competence and avoids concept padding. Its weaknesses are structural: a monolithic single-file layout with no progressive disclosure, and workflows that omit validation checkpoints for fragile repackaging/signing steps.

Suggestions

Add validation/feedback checkpoints to the tampering workflow — e.g. verify `apktool b` produced the APK, run `apksigner verify`, and confirm the patched app launches on-device before declaring success — so errors can be caught and retried.

Split the monolithic body into one-level-deep bundle references (e.g. references/frida-hooks.md, references/exported-components.md, references/cloud-misconfig.md) and keep SKILL.md as an overview that links out, rather than inlining every script and command catalog.

Reconcile the redundancy between the Quick Workflow, the Engagement Checklist, and the Detection/Defender table so each bypass appears once and the checklist serves as the single gated end-to-end sequence with verify-gates between phases.

DimensionReasoningScore

Conciseness

The body is mostly lean and command/code-dense with little concept over-explanation, but there is mild redundancy — the Quick Workflow overlaps the Engagement Checklist, and the Detection/Defender table re-covers bypasses already shown in the Frida section — that could be trimmed.

4 / 5

Actionability

Guidance is fully executable throughout: apktool/jadx/drozer commands, copy-paste Frida JS hooks, objection shortcuts, curl/grep one-liners, and smali patch + apksigner flows cover the common cases concretely.

5 / 5

Workflow Clarity

A clear sequence exists (5-step Quick Workflow plus a 16-item Engagement Checklist), but there are no validation/feedback checkpoints, and the destructive repackaging flow (apktool b → apksigner sign → adb install) lacks any verify-gate, capping this dimension per the rubric.

3 / 5

Progressive Disclosure

Sections are well-organized with clear headers and external references (OWASP MASTG, Frida CodeShare, MobSF) are signaled, but no bundle files exist and all deep content — Frida hook catalogs, drozer usage, cloud misconfig — is inlined in one monolithic file rather than split into one-level-deep references.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, information-dense description that clearly states the skill's mobile offensive-testing scope and gives explicit usage triggers. It is verbose but every item is a concrete capability rather than fluff, so verbosity does not dilute specificity.

DimensionReasoningScore

Specificity

The description enumerates many concrete actions tied to specific tooling — 'static analysis (apktool/jadx for Android, class-dump/Hopper/IDA for iOS)', 'dynamic instrumentation with Frida and Objection', 'SSL pinning bypass', 'exported component attacks', 'Keychain ACL bypass' — giving comprehensive, non-vague coverage rather than abstract language.

5 / 5

Completeness

It explicitly answers both 'what' (the long enumeration of capabilities) and 'when' via the closing 'Use for mobile pentest, bug bounty mobile triage, or app-store reconnaissance.' clause with concrete trigger scenarios.

5 / 5

Trigger Term Quality

Natural user-facing phrases appear directly: 'mobile pentest', 'bug bounty mobile triage', 'app-store reconnaissance', plus domain terms 'Android', 'iOS', 'Frida'. Coverage of natural trigger phrasings is comprehensive for this niche.

5 / 5

Distinctiveness Conflict Risk

The niche is sharply scoped to 'Mobile (Android + iOS) application penetration testing' with distinct offensive triggers, making overlap with generic web or desktop pentest skills minimal.
