mobile

mobile is a skill for Claude Code from MingyiSecLab/Mingyi-Atlas. It costs 39 tokens per session (702 once invoked), scanned A, original, Apache-2.0.

A guide for testing mobile applications as security targets, covering Android APKs and iOS IPA files. It routes work to the relevant platform and attack surface, including the APIs behind the app.

In plain words
What is it for?
Use it to acquire and inspect mobile app packages, review permissions and code, instrument apps at runtime, inspect network traffic, and continue testing the backend APIs used by the app.
Why use it?
It helps testers choose the right checks and tools instead of treating every mobile application the same way.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mobile scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Mobile Application Red Team — Category Overview

This is a routing skill. Identify the target platform and the relevant attack surface, then load the specialized sub-skill.

Sub-Skills

Sub-Skill Covers When to Load
android APK static (apktool/jadx) + dynamic (Frida/Objection), SSL pinning bypass, root detection bypass, intent fuzzing, keystore extraction, exported components Android .apk file in scope, Play-Store target, MDM-managed Android device

Workflow

  1. Acquire — APK from Play Store (apkpure / apkmirror), MDM extraction (adb shell pm path <pkg>), or device pull (adb pull)
  2. Static — Pre-pull strings, manifest, permissions; decompile to Java/Smali
  3. Dynamic — Frida or Objection on a rooted/emulated device; instrument crypto, network, storage
  4. Network — Burp / mitmproxy with patched APK or Frida SSL-pin bypass
  5. Backend — The APK is the door — the API behind it is the real attack surface; pivot to standard/exploit/web/ once you have endpoints and tokens

Tooling

Tool Use
apktool Smali decompile / recompile / re-sign
jadx Java pseudocode from DEX
frida / frida-tools Runtime instrumentation
objection Frida wrapper — ready-made bypass scripts
mobsf Automated SAST+DAST first-pass triage
drozer IPC / exported-component fuzzer
apksigner / zipalign Re-sign modified APKs for re-install
frida-ssl-pin-bypass Universal SSL-pinning patches
nox / genymotion / android-studio AVD Emulators (x86_64 for speed)

Decision Notes

  • iOS coverage (sub-skill ios/) is on the roadmap — for iOS work today, leverage the same dynamic patterns (Frida + Objection) and load android/SKILL.md for the methodology since the analytical workflow is platform-agnostic.
  • Mobile backend exploitation almost always pivots to web/API testing — after token extraction, load /skills/standard/exploit/web/SKILL.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
