Add registry rules for additional SMSS persistence vectors
Pull Request
Summary - What I changed
Add additional registry entries for uncommon Windows persistence registry techniques. SMSS.exe will launch a number of additional registry entries as native applications before win32k subsystem init, this can be leveraging for persistence.
How To Test
You can build a native application, an example https://github.com/rad9800/BootExecuteEDR, place the binary in C:\Windows\System32 and add the registry entry (updating the command for the relevant key).
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager" /v "BootExecute" /t REG_MULTI_SZ /d "autocheck autochk *\0BEB" /f
Automated testing was not added, as it is not currently present for existing BootExecute detections.
