re-harmonyos

re-harmonyos is a skill for Claude Code from dslsdzc/rev-skills. It costs 64 tokens per session (2,532 once invoked), scanned A, original, Apache-2.0.

A workflow for reverse engineering HarmonyOS application packages such as HAP, HSP, and HAR files. It covers package contents, resources, ArkTS code compiled into ABC bytecode, and native libraries.

In plain words
What is it for?
Use it to unpack HarmonyOS packages, inspect module configuration and resources, extract strings, analyse ArkTS bytecode, and examine included native `.so` libraries.
Why use it?
It helps developers and investigators inspect HarmonyOS applications when the original project is unavailable. It also distinguishes this package format from Android APK files and ordinary web applications.

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-harmonyos 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 10d 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.

鸿蒙应用逆向(HarmonyOS / hap / ArkTS)

何时使用 / 何时不用

  • 用:拿到 hap(应用发布包)/ hsp(共享包)/ har(静态库归档),需要看模块配置、资源、ArkTS 业务逻辑
  • 用:需要还原 .abc 字节码(ArkCompiler 产物)中的业务逻辑——字符串定位、反汇编、混淆还原
  • 用:鸿蒙应用含 native 库(libs/ 下 .so),需要静态/动态联动分析
  • 不用:普通 Android APK(走 [[re-apk]];dex/smali 体系与本技能不同)
  • 不用:纯 Web/前端应用(非鸿蒙容器,脚本/Web 路径走 [[re-script-deob]] 或 [[re-browser-ext]])
  • 注意:动态执行默认沙箱([[platform-tips]] 最高原则)——静态解包/反汇编免沙箱;模拟器/真机运行观察必须进 [[re-sandbox]]

工具准备

参考 [[platform-tips]]——静态分析(解包、字符串、反汇编)免沙箱;动态步骤按最高原则进沙箱。

hap 解包(zip 容器,通用思路)

  • hap = zip 容器,与 APK 同源(同属 zip/jar 家族)——任何通用 zip 解包工具都能解(unzip / 7-Zip / python3 zipfile 模块),不绑死单一实现
  • 流程与 [[re-apk]] 同源:先列清单(unzip -l)→ 再解包 → 验证完整性(CRC/文件数对照)
  • 专业解包工具(集成 module.json 解析与资源提取)可作备选,注意按发行版本选择对应版本
  • 验证: 解包后目录结构完整(对照步骤 1 的清单)

python3(字符串提取与脚本)

  • Linux: apt install python3 / dnf install python3 / pacman -S python;macOS: 自带;Windows: 官方安装器
  • zipfile 为标准库:python3 -m zipfile -l app.hap 列清单、python3 -m zipfile -e app.hap out/ 解包
  • 验证: python3 --version

字符串/资源提取工具

  • strings(binutils 自带)与 grep:捞 .abc 与资源中的 URL、密钥、提示语
  • 资源文件(布局、图片、rawfile)先用 file 判断类型再提取

ArkCompiler 反汇编器(针对 abc 的替代,泛化描述)

  • [[re-java]] 的 jadx 类思路复用:Android 用 jadx 解 dex,鸿蒙侧对应的是 ArkCompiler 反汇编工具——官方工具链(随 SDK 发行)与开源实现均可,选能输出指令级汇编(指令助记符 + 操作数/常量引用)的实现即可,多个实现可交叉验证
  • 版本匹配:先识别编译版本再选工具(见坑 2)

操作步骤

按顺序执行;每步产物(解包目录、反汇编输出 + sha256)存档(见 [[re-triage]])。

  1. 包结构识别与解包

    file app.hap
    unzip -l app.hap | head -30
    unzip -o app.hap -d out/
    
    • hap ≈ APK 变体:module.json(模块配置,等价 manifest:入口/权限/组件声明)、resources/(资源,等价 res/)、ets/(ArkTS 编译产物所在,.abc 字节码)、libs/(native .so)、assets/(rawfile 等原始资源)
    • hsp / har 同为 zip 容器,结构类似(hsp 含 .abc,har 为静态库归档),解包流程一致
    • zip 容器解包流程与 APK 同源([[re-apk]]):列清单 → 解包 → 校验;发现嵌套容器则递归解(见坑 4)
  2. 字节码识别(.abc)

    find out/ -name "*.abc" | head
    xxd out/ets/modules.abc | head -10    # 看文件头
    
    • .abc 是 ArkCompiler(方舟编译器)字节码文件,业务逻辑主体;文件头含固定魔数与版本字段,其后为段结构(字符串段/字面量段/指令段等,具体布局随编译版本演进)
    • 旧版本布局有差异(模块文件命名/位置不同)——以解包清单为准;file 识别不出时用 xxd/python3 读头部,先识别编译版本再定工具(见坑 2)

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.
