An Android application penetration-testing workflow for examining APK files and testing how an app behaves on a device. It covers both offline code inspection and live testing with instrumentation tools.

Use it to decompile an APK, inspect its manifest and permissions, observe runtime behavior, bypass certificate pinning or root checks during authorized tests, fuzz intents, and examine keystores.

It gives security testers a structured way to find exposed app components, unsafe settings, weak certificate checks, root-detection gaps, and sensitive data stored in the app.

android — Skill for Claude Code and Codex by MingyiSecLab

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add MingyiSecLab/Mingyi-Atlas --skill android

Clone the repo

git clone --depth 1 https://github.com/MingyiSecLab/Mingyi-Atlas

Made for: Claude Code, Codex.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00036	$0.01973
Opus 5	$0.00018	$0.00986
Sonnet 5	$0.00007	$0.00395
Haiku 4.5	$0.00004	$0.00197

Security

Grade B, and why

android scanned grade B with 2 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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

adb shell "chmod 755 /data/local/tmp/frida-server && /data/local/tmp/frida-server &"

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- Demonstrate exposed component RCE → `adb shell am start -n ... --es cmd 'rm -rf'`

Android Pentest Playbook

1. Static — decompile + inspect

Pull APK

# Listed apps on connected device
adb shell pm list packages -3            # third-party only
adb shell pm path com.target.app         # find APK path
adb pull /data/app/.../base.apk /tmp/

# Or from Google Play
gplaycli -d com.target.app -f /tmp/      # CLI Play store dump

# Or from third-party APK mirrors (apkpure / apkmirror)

Decompile

# Smali (low-level)
apktool d base.apk -o /tmp/apk-smali

# Java pseudo-code (jadx)
jadx --output-dir /tmp/apk-java base.apk
# Or jadx-gui for interactive

# Combine for full picture

MobSF automated triage

docker run -it --rm -p 8000:8000 opensecurity/mobile-security-framework-mobsf
# Upload APK via web UI, get full report

Manifest review

apkanalyzer manifest print base.apk
# OR
aapt dump xmltree base.apk AndroidManifest.xml | head -50

# Critical signals:
# - android:debuggable="true"        → debugger attachable
# - android:allowBackup="true"       → adb backup possible w/o root
# - android:exported="true" w/o perm → exposed component
# - <uses-permission> SMS/CAMERA/MIC reach  → privacy risk
# - <intent-filter> w/ "android.intent.action.VIEW" + custom scheme → deeplink
# - networkSecurityConfig: cleartextTrafficPermitted="true" → MITM-friendly

Secrets sweep

# Hardcoded keys in smali / java code
grep -rn 'api[_-]?key\|secret\|password' /tmp/apk-java/ | head -20

# Strings + entropy
strings -a base.apk | grep -E 'eyJhbGc|^[A-Za-z0-9+/]{30,}={0,2}$' | head

# AndroGuard for deep static
androguard analyze base.apk

2. Dynamic — Frida + Objection

Setup

# Push frida-server (rooted device / emulator)
adb push frida-server-16.x.x-android-arm64 /data/local/tmp/
adb shell "chmod 755 /data/local/tmp/frida-server && /data/local/tmp/frida-server &"

# Or use Magisk module on prod devices

Bypass SSL pinning (Frida codeshare scripts)

frida -U -l https://codeshare.frida.re/@pcipolloni/universal-android-ssl-pinning-bypass-with-frida/ -f com.target.app

# Or Objection's built-in
objection -g com.target.app explore
> android sslpinning disable

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.

android is a skill published in the GitHub repository MingyiSecLab/Mingyi-Atlas (11 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 36 tokens to every session and 1,973 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
