mobile-app-security-testing

mobile-app-security-testing is a skill for Claude Code, Codex from liuxinye23/CyberStrikeAI. It costs 15 tokens per session (1,934 once invoked), scanned A, original, Apache-2.0.

A methodology for testing the security of Android and iOS mobile applications. It covers the app itself, stored and transmitted data, authentication, permissions, sessions and network communications.

In plain words
What is it for?
Reviewing code protection, certificate checks, encryption, token handling, sensitive storage, biometric and session controls, TLS settings, APIs and resistance to interception.
Why use it?
It gives testers a checklist for common mobile risks that can be missed when looking only at the app interface. It also describes static analysis, runtime inspection and traffic testing approaches.

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-app-security-testing 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.

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.

移动应用安全测试

概述

移动应用安全测试是确保移动应用安全性的重要环节。本技能提供移动应用安全测试的方法、工具和最佳实践,涵盖Android和iOS平台。

测试范围

1. 应用安全

检查项目:

  • 代码混淆
  • 反编译防护
  • 调试防护
  • 证书绑定

2. 数据安全

检查项目:

  • 数据加密
  • 密钥管理
  • 敏感数据存储
  • 数据传输

3. 认证授权

检查项目:

  • 认证机制
  • Token管理
  • 生物识别
  • 会话管理

4. 通信安全

检查项目:

  • TLS/SSL配置
  • 证书验证
  • API安全
  • 中间人攻击防护

Android安全测试

静态分析

使用APKTool:

# 反编译APK
apktool d app.apk

# 查看AndroidManifest.xml
cat app/AndroidManifest.xml

# 查看Smali代码
find app/smali -name "*.smali"

使用Jadx:

# 反编译APK
jadx -d output app.apk

# 查看Java源码
find output -name "*.java"

使用MobSF:

# 启动MobSF
docker run -it -p 8000:8000 opensecurity/mobsf

# 上传APK进行分析
# 访问 http://localhost:8000

动态分析

使用Frida:

// Hook函数
Java.perform(function() {
    var MainActivity = Java.use("com.example.MainActivity");
    MainActivity.onCreate.implementation = function(savedInstanceState) {
        console.log("[*] onCreate called");
        this.onCreate(savedInstanceState);
    };
});

使用Objection:

# 启动Objection
objection -g com.example.app explore

# Hook函数
android hooking watch class_method com.example.MainActivity.onCreate

使用Burp Suite:

# 配置代理
# Android设置代理指向Burp Suite
# 安装Burp证书

常见漏洞

硬编码密钥:

// 不安全的代码
String apiKey = "1234567890abcdef";
String password = "admin123";

不安全的存储:

// SharedPreferences存储敏感数据
SharedPreferences prefs = getSharedPreferences("data", MODE_WORLD_READABLE);
prefs.edit().putString("password", password).apply();

证书验证绕过:

// 不验证证书
TrustManager[] trustAllCerts = new TrustManager[] {
    new X509TrustManager() {
        public X509Certificate[] getAcceptedIssuers() { return null; }
        public void checkClientTrusted(X509Certificate[] certs, String authType) { }
        public void checkServerTrusted(X509Certificate[] certs, String authType) { }
    }
};

iOS安全测试

静态分析

使用class-dump:

# 导出头文件
class-dump app.ipa

# 查看头文件
find app -name "*.h"

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.
