What it detects
This rule detects DNS queries to Google Sheets or Drive API hosts originating from a process running out of a temporary or user AppData directory, a covert command-and-control channel described by Intel 471. Malware abuses trusted Google API endpoints to blend beacon traffic with normal web activity, so API lookups from temp-resident binaries are a heuristic C2 indicator that benefits from process-path context to reduce noise.
