mobile-hardening

mobile-hardening is a command for Claude Code from HermeticOrmus/LibreSecOps-Claude-Code. It costs 38 tokens per session (912 once invoked), scanned A, original, MIT.

A command that creates a platform-specific security-hardening checklist for an Android or iOS app. Hardening means adding protections that make an application more resistant to attack and tampering.

In plain words
What is it for?
Planning protections for data storage, network communication, app binaries, anti-tampering, and MASVS security levels before production release.
Why use it?
It helps teams turn a security target or penetration-test report into concrete release and remediation tasks.

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-hardening 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 12d 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-hardening

Generate a platform-specific hardening checklist for an Android or iOS application, covering data storage, network security, binary protections, and anti-tampering.

Trigger

Use before releasing a mobile application to production, or when preparing a security hardening plan for an existing application. Particularly valuable for:

  • Pre-release security hardening pass
  • Responding to a penetration test report with hardening recommendations
  • Upgrading an application from MASVS-L1 to MASVS-L2
  • Adding resilience controls for apps with client-side IP protection needs

Input

  • Platform: Android or iOS (required)
  • Language/Framework: Kotlin, Java, Swift, Objective-C, React Native, Flutter
  • Risk profile: Financial/banking, healthcare, enterprise, general consumer
  • Current state: What security controls are already in place (if known)
  • Target MASVS level: L1 (baseline), L2 (defense-in-depth), L2+R (with resilience)
  • Specific concerns: Any particular areas of focus

Process

  1. Determine hardening scope based on platform, risk profile, and target MASVS level

  2. Generate data storage hardening checklist:

    • Migrate sensitive data to platform secure storage
    • Configure backup exclusions (android:allowBackup="false", excluded files on iOS)
    • Disable screenshot capture for sensitive screens
    • Clear clipboard on app background/foreground transitions
    • Configure logging to exclude sensitive data in release builds
    • Implement proper file permissions for app-created files
  3. Generate network security hardening checklist:

    • Configure minimum TLS version (1.2+, prefer 1.3)
    • Implement certificate pinning (with backup pins and rotation plan)
    • Remove cleartext traffic exceptions
    • Configure ATS (iOS) or Network Security Config (Android)
    • Implement proper certificate validation in custom handlers
  4. Generate authentication hardening checklist:

    • Bind biometric authentication to cryptographic operations
    • Implement secure session management with proper token storage
    • Add step-up authentication for sensitive operations
    • Configure auto-lock timeout for sensitive apps
    • Implement device binding where appropriate

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.

mobile-hardening is a command published in the GitHub repository HermeticOrmus/LibreSecOps-Claude-Code (4 stars, last pushed 9d ago), licensed MIT. It adds 38 tokens to every session and 912 once invoked, about $0.0002 per session on Opus 5.5. 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.
