    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

conducting-mobile-app-penetration-test 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/agent.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Conducting Mobile App Penetration Test

When to Use

  • Testing mobile applications before release to identify security vulnerabilities and data protection issues
  • Conducting compliance assessments against OWASP MASVS (Mobile Application Security Verification Standard) levels L1 and L2
  • Evaluating the security of mobile banking, healthcare, or government applications handling sensitive data
  • Testing mobile apps that interact with backend APIs to assess the end-to-end security of the mobile ecosystem
  • Assessing mobile application resistance to reverse engineering, tampering, and runtime manipulation

Do not use against mobile applications without written authorization from the application owner, for distributing modified or repackaged applications, or for testing apps on the public app stores without a separate test build.

Prerequisites

  • Target application IPA (iOS) and APK (Android) files or access to download from a private distribution channel
  • Rooted Android device or emulator (Genymotion, Android Studio AVD) with Frida, Objection, and Magisk installed
  • Jailbroken iOS device or Corellium virtual device with Frida, Objection, and SSL Kill Switch installed
  • Static analysis tools: jadx (Android decompilation), Hopper/Ghidra (iOS binary analysis), MobSF (automated scanning)
  • Burp Suite Professional configured as proxy for intercepting mobile app traffic with CA certificate installed on the test device

Legal Notice: This skill is for authorized security testing and educational purposes only. Unauthorized use against systems you do not own or have written permission to test is illegal and may violate computer fraud laws.

Workflow

Step 1: Static Analysis

Analyze the application binary without executing it:

Android Static Analysis:

  • Decompile the APK: jadx -d output/ target.apk to obtain Java/Kotlin source code
  • Review AndroidManifest.xml for exported components (activities, services, receivers, content providers), permissions, and debuggable flag
  • Search for hardcoded secrets: grep -rn "api_key\|password\|secret\|token\|aws_" output/
  • Identify insecure data storage patterns: SharedPreferences with sensitive data, SQLite databases without encryption, files in external storage
  • Check for WebView vulnerabilities: setJavaScriptEnabled(true), addJavascriptInterface(), and loading untrusted content
  • Run MobSF automated scan: python manage.py runserver and upload the APK for automated static analysis

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.

conducting-mobile-app-penetration-test is a skill published in the GitHub repository 26zl/cybersec-toolkit (54 stars, last pushed today), licensed MIT. It adds 108 tokens to every session and 2,696 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
