attack_technique: T1122
display_name: Component Object Model (COM) Hijacking
atomic_tests:
- name: COM Hijack Leveraging .NET profiler DLL
description: |
Creates environment variables and CLSID to enable a .NET profiler. The profiler DLL (`atomicNotepad.dll`) executes when the CLR is loaded by the Event Viewer process. Additionally, the profiling DLL will inherit the integrity level of Event Viewer bypassing UAC and executing `notepad.exe` with high integrity. If the account used is not a local administrator the profiler DLL will still execute each time the CLR is loaded by a process, however, the notepad process will not execute with high integrity.
