competition-android-hooking
Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for Android APK hooking, Frida tracing, request-signing recovery, SSL pinning bypass, JNI boundary inspection, and app trust-boundary analysis. Use when the user asks to hook an APK, inspect signer logic, trace Java or native boundaries, bypass pinning or root checks, inspect shared prefs or app databases, or replay accepted mobile requests. Use only after $ctf-sandbox-orchestrator has already established sandbox assumptions and routed here.

Competition Android Hooking
Use this skill only as a downstream specialization after $ctf-sandbox-orchestrator is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to $ctf-sandbox-orchestrator first.
Use this skill when the decisive path runs through an Android app's live trust boundary rather than static strings alone.
Reply in Simplified Chinese unless the user explicitly requests English.
Quick Start
- Preserve the original APK, extracted resources, and decompiled output before patching or resigning.
- Start with manifest, exported components, deeplinks, native libs, prefs, local DBs, and bundled configs.
- Decide the narrowest runtime boundary to hook: signer, crypto helper, JNI bridge, WebView bridge, or request builder.
- Correlate static evidence and dynamic traces before claiming a trust edge is understood.
- Reproduce the signed request, accepted token, or gated branch from the smallest hook set.
Workflow
1. Static Triage Before Hooks
- Map package structure, exported activities, services, receivers, providers, and deeplink handlers.
- Note SSL pinning logic, root checks, feature flags, token storage, shared prefs, SQLite tables, and protobuf or RPC boundaries.
- Identify whether the sensitive logic sits in Java, Kotlin, JNI, or a bundled WebView.
2. Hook The Narrowest Boundary
- Prefer hooking request signers, crypto helpers, keystore access, protobuf encode or decode, or JNI marshaling instead of broad UI hooks.
- Record plaintext inputs, signed strings, headers, nonces, and outputs at the boundary that actually changes trust.
- If pinning or environment checks block progress, patch or hook only enough to expose the real request path.
3. Replay The Accepted Path
- Rebuild the smallest sequence that reaches the accepted server-side branch: local state, nonce, request body, signature, and headers.
- Keep hook logs, captured request shapes, and local storage paths tied to the same account or session state.
- If the challenge becomes more about transform recovery than Android runtime, switch back to the broader crypto or mobile skill.

What To Preserve
- Hook points, class names, JNI symbols, signer inputs and outputs, and header names
- Shared prefs, local DB rows, deeplinks, exported components, and token storage paths
- The smallest replayable request or branch that proves the trust boundary

reverse-engineering
zhaoxuya520/reverse-skill
Provides reverse engineering techniques. Use when the main job is to understand how a compiled, obfuscated, packed, or virtualized target works before exploiting or solving it, including binaries, APKs, WASM, firmware, custom VMs, bytecode, malware-like loaders, and anti-debug or anti-analysis logic. Do not use it when the vulnerability is already understood and the remaining task is exploitation; use pwn instead. Do not use it for pure web workflows, log or disk forensics, or standalone crypto problems unless reversing the implementation is the real blocker.

ida-reverse
zhaoxuya520/reverse-skill
IDA Pro 逆向分析辅助技能。当用户提到逆向、反编译、分析二进制/PE/ELF/APK/DLL/SO、破解、找密码、漏洞分析、病毒分析、firmware 固件分析，或需要分析 exe/dll/so/elf/macho/sys 等文件时，务必使用此技能。 Ensure to use this skill when the user wants to analyze any binary file, regardless of whether they explicitly mention "IDA" or "reverse engineering". This includes requests like "看看这个exe", "分析这个dll", "帮我破解", "找一下密码", "这个软件怎么注册", etc. Use the bundled scripts (scripts/start.ps1, scripts/open.ps1) for deterministic server management and file opening — do NOT write ad-hoc PowerShell commands for these operations.
