What it detects

This rule detects execution of agent.exe from the Microsoft WinSyncDefender folder under AppData Roaming, the staging path used by Operation ShadowRecruit to host its SheetAgent RAT payload. Running a generically named binary from a fake Microsoft directory in a user-writable location is a wrong-context indicator of the recruitment-themed campaign against Indian job seekers, exposing the malware between delivery and Google Sheets C2.
