dotnet-reverse SKILL.md skillA
dotnet-reverse from skillmds/skillmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add skillmds/skillmd/dotnet-reverse@git:20260919.fecc0d5Pins git:20260919.fecc0d5 in mdr.lock. Pin the fingerprint instead.

.NET / C# 二进制逆向。当目标是 .NET assembly（PE 头含 CLR、.exe/.dll 托管程序）、C# 编译产物（含 NativeAOT）、红队 Sharp* 工具（Rubeus / SharpHound / SharpHound 等）、.NET 混淆程序（ConfuserEx / SmartAssembly / Babel / Eazfuscator）、.NET loader / info-stealer / 套壳 malware 时使用。优先用 dnSpyEx + de4dot，需要 AI 直接操作时联动 dnSpy MCP。不用于纯 native 二进制（走 reverse-engineering / ida-reverse）。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# .NET / C# 逆向作业规范 ## ACTION REQUIRED（读完立刻执行） 1. `NOW`: 用 DIE/`file`/CLR 头确认目标是 .NET 托管（否则 SWITCH 到 `ida-reverse/` / `reverse-engineering/`） 2. `NOW`: 若疑似混淆 → 先 `de4dot` 脱壳，产出 `*-clean.exe`，保留原始样本 3. `NEXT`: dnSpyEx（或 dnSpy MCP / `ilspycmd`）静态：C# 浏览 + **IL 视图**看关键判断 4. `ACT`: 需要明文/C2 时动态调试；需要改逻辑时 **IL patch** 优先于 C# 重编译 5. 阶段结束给用户 3–6 项下一步菜单（含导出报告） ## 适用范围 当任务属于以下场景时优先使用本 skill： - 识别并逆向 .NET / C# 编译产物（托管 PE / .exe / .dll） - 分析红队 Sharp* 工具链（Rubeus、SharpHound、SharpShell 等） - 脱混淆 ConfuserEx / SmartAssembly / Babel / Eazfuscator / .NET Reactor 等壳 - 逆向 .NET loader / info-stealer / RAT 的解密与 C2 逻辑 - 对 C# 程序做 patch（改判断、改常量、keygen） - 分析 IL2CPP 之前的 Mono/Unity 托管层（注意：IL2CPP 编译后是 native，走 `reverse-engineering/` + seed-014） 如果目标是纯 native 二进制（C/C++/Go/Rust 编译、无 CLR），请改用 `reverse-engineering/`、`ida-reverse/` 或 `radare2/`。 ## 核心原则 - **先识别再下手**：先确认是 .NET 托管程序（PE 头 CLR + `#~` / `#Strings` 流 + mscoree `_CorExeMain`），再决定走 dnSpy 而非 IDA - **IL 优先于 C#**：dnSpyEx 的 C# 反编译器会丢失/扭曲信息（编译器生成的状态机、async/await、yield），关键判断与 patch 必须切到 **IL 编辑器**，C# 视图只用于快速浏览 - **de4dot 先行**：遇到混淆器先 `de4dot` 脱一轮再做静态分析，否则字符串/控制流全是乱的 - **MCP 联动**：环境里若注册了 dnSpy MCP（`dnspy_*` 工具），优先走 MCP 面做 decompile / IL inspection，避免来回切 GUI …

How to install
mdr add skillmds/skillmd/dotnet-reverse@sha256:d7e207e843fe9834The line at the top of this page pins the label git:20260919.fecc0d5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
