What it detects

This rule detects the Windows print spooler binary name spoolsv.exe executing from a directory outside System32 which the CoralRaider RotBot component uses to masquerade as a trusted system service. Running a well-known system image name from a wrong location is a strong masquerading signal used to evade defender and analyst attention.
