re-mobile

re-mobile is a skill for Claude Code from dslsdzc/rev-skills. It costs 4 tokens per session (2,171 once invoked), scanned A, original, Apache-2.0.

A workflow for analysing Android and iOS applications through unpacking, decompilation, runtime instrumentation, and native-library inspection. Decompilation turns compiled code into a more readable form, while instrumentation observes or changes it while it runs.

In plain words
What is it for?
Use it to inspect app permissions and components, read Android or iOS code, analyse native libraries, observe runtime calls, and document findings with stored evidence.
Why use it?
It brings the main mobile-analysis tasks together and helps choose the right path for APKs, IPAs, native libraries, protected apps, and runtime behaviour.

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

re-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.

完整工作流

  1. 初勘:[[re-triage]] —— file/哈希/熵确认输入类型(APK 与 IPA 都是 ZIP 容器,file 报 ZIP;纯 .so / Framework dylib 直接进第 4 步);未走 [[re-analyze]] 入口则先补做,读取 RE_* 会话变量
  2. 静态:
    • Android:[[re-apk]] —— apktool 解包、AndroidManifest 入口/权限/组件、jadx 反编译 Java、smali 补丁思路、加固识别
    • iOS:[[re-ios]] —— ipa 解包与签名检查、class-dump 头文件、加密二进制脱壳
  3. 动态:[[re-frida]] —— 需要运行时行为(解密、hook、绕过证书/检测、观察调用链)时 spawn/attach 插桩;iOS 断点调试走 [[re-lldb]]
  4. 原生库:移动 App 含原生代码(Android lib/*.so、iOS Framework 内 dylib)→ [[re-binary-core]]:[[re-format-elf]](Android)/ [[re-format-macho]](iOS)解析格式,[[re-ghidra]] 反编译 JNI/OC 底层逻辑;Android native 深挖(JNI 注册还原、so 逻辑)走 [[re-android-native]];iOS 越狱环境(越狱检测 / tweak / 动态调试)走 [[re-ios-jb]]
  5. 加固/带壳:[[re-apk]] 识别加固后转脱壳域([[re-anti-analysis]],Android);iOS App Store 加密二进制按 [[re-ios]] 脱壳(frida-ios-dump 思路)。脱壳产物回到步骤 2 复跑
  6. 产出:结论/报告(按 RE_REPORT),哈希与证据存档(见 [[re-triage]])

每步结果存档(证据路径 + sha256,见 [[re-triage]]),供报告引用;发现恶意样本/回连随时转 [[re-malware]]。

何时用哪个原子技能(选择树)

  • 输入是 APK / 目标为 Android → [[re-apk]] 静态 → 需要运行时 → [[re-frida]]
  • 输入是 IPA / 目标为 iOS → [[re-ios]] 静态 + 脱壳 → 断点调试 [[re-lldb]] / 插桩 [[re-frida]]
  • 目标含原生库(.so / dylib)→ [[re-binary-core]]([[re-format-elf]] / [[re-format-macho]] / [[re-ghidra]]);Android native 专项(JNI/so)→ [[re-android-native]]
  • 目标有越狱检测 / 要 tweak 分析 / 越狱设备动态调试 → [[re-ios-jb]]
  • 需要解密 / 绕过证书 / hook 函数 / 观察调用链 → [[re-frida]]
  • 加固/带壳:Android → [[re-anti-analysis]](先经 [[re-apk]] 识别);iOS 加密 → [[re-ios]] 脱壳
  • Android 加固脱壳专项(乐固/360/梆梆/爱加密)→ [[re-mobile-pack]](识别后运行/静态脱壳 + DEX 修复)
  • Flutter / React Native 混合应用 → [[re-hybrid-app]](引擎识别 → blutter / hermes-dec)
  • 提取运行时内存中的 DEX/密钥 → [[re-memdump]](DEX 提取见该技能)

跨域联合

  • 移动 App 含原生库:[[re-mobile]] → [[re-binary-core]]([[re-format-elf]] / [[re-ghidra]] 反编译 JNI/OC 底层逻辑);Android native 专项 [[re-android-native]];iOS 越狱环境 [[re-ios-jb]](越狱检测 / tweak / lldb 远程)
  • 移动 App 加固/带壳:[[re-mobile]] → [[re-anti-analysis]](Android 脱壳);iOS 加密二进制 [[re-ios]] 脱壳
  • 动态分析默认沙箱:模拟器快照 / 受控越狱设备 + 网络隔离([[platform-tips]] 最高原则)
  • 移动恶意样本/回连:[[re-mobile]] → [[re-malware]](行为分析见 [[re-sandbox]])
  • 本网关被 [[re-analyze]] 的 triage.md「移动 App 分析」路径调用(re-mobile → re-apk / re-ios → re-frida → 若含原生库 re-binary-core)

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.
