SNOWLIGHT Dropper wusvc.exe Masquerading as Windows Update Service
This rule detects potential malicious activity involving the 'wusvc.exe' executable. It flags instances where 'wusvc.exe' is executed from the user's Downloads folder or other non-standard paths, particularly when the file size is abnormally small (less than 100KB), which is indicative of masquerading or a dropper payload. The rule also checks for a known malicious file hash associated with the Snowlight dropper.
