- Multi-stage Dockerfile: discover patterns from PMS binary (capstone), compile .so with zig (musl), layer onto lscr.io/linuxserver/plex - Uses LD_PRELOAD instead of patchelf (which corrupts Plex's musl loader) - Auto-discovery: broad structural patterns with string-anchored fallback (//feature) and relationship-based fallback (BITSET_REF within BS_INIT) - hook.cpp uses __has_include for generated patterns with hardcoded fallbacks - Custom wrapper.sh (no traffic_logger preload) - Vendored Freeloader source (github.com/authrequest/Freeloader, AGPL-3.0) - Removed stale plexmediaserver_crack.so binary - Supports Plex 1.43.3+ (verified against 1.43.2 and 1.43.3)

# Windows patching guide
|
|
|
|
Top-level index for the Windows x64 Plex Media Server work in this repo.
|
|
|
|
## What exists
|
|
|
|
The Windows implementation lives in [`../windows/`](../windows/) and contains:
|
|
|
|
- `plex_patch.dll` — injected payload that forces the feature bitset on
|
|
- `plex_inject.exe` — injector that attaches to or launches `Plex Media Server.exe`
|
|
- a small engine split into:
|
|
- `pe_image.h` — PE parsing, section bounds, RVA resolution, version guard
|
|
- `sig_scan.h` — byte-pattern scanning helpers
|
|
- `trampoline.h` — Zydis-based x64 inline hook engine
|
|
- `feature_patch.h` — bitset forcing, populator hook, guard thread
|
|
|
|
## Current target
|
|
|
|
Pinned to:
|
|
|
|
- **Plex Media Server** `1.43.2.10687-563d026ea`
|
|
- **Platform**: Windows x64
|
|
|
|
The patch uses a **version guard** and **bounds-checked RVA resolution** before
|
|
it touches the target process.
|
|
|
|
## Build
|
|
|
|
From `windows/`:
|
|
|
|
```bat
|
|
build.bat
|
|
```
|
|
|
|
This produces:
|
|
|
|
- `build\plex_patch.dll`
|
|
- `build\plex_inject.exe`
|
|
|
|
The build reuses the repo's vendored Zydis and Zig toolchain conventions.
|
|
|
|
## Run
|
|
|
|
Attach to a running PMS:
|
|
|
|
```bat
|
|
build\plex_inject.exe
|
|
```
|
|
|
|
Or launch PMS through the injector:
|
|
|
|
```bat
|
|
build\plex_inject.exe --launch "C:\Program Files\Plex\Plex Media Server\Plex Media Server.exe"
|
|
```
|
|

## Notes
|
|
|
|
- `windows/build/` artifacts are intentionally git-ignored.
|
|
- The original incompatible `.i64` was left untouched; the working Windows IDB
|
|
was rebuilt in a writable analysis directory during RE.
