+name: UAC bypass via .NET Code Profiler DLL Hijack
+id: 554f1b0d-c317-4cf0-aaac-d29d6e046b0c
+version: 1.0.0
+description: |
+  Identifies potential User Account Control (UAC) bypass activity leveraging
+  the .NET Code Profiler mechanism to achieve elevated code execution through
+  DLL hijacking. Attackers may attempt to load arbitrary profiler libraries
+  into high-integrity processes.
