Kernel Driver Staged in Windows Fonts Directory
This rule detects the creation or loading of a .sys file (kernel driver) within the Windows Fonts directory by a non-standard loader. This behavior is suspicious as the Fonts directory is not a typical location for kernel drivers, and the use of common command-line interpreters (cmd, powershell, pwsh, rundll32, regsvr32) or other executables to stage or load such files indicates potential malicious activity, possibly related to defense evasion or persistence.
