What it detects

This rule identifies Windows file deletions where the target filename contains \TeamViewer_ and ends with .log. Deleting application logs can indicate an attempt to hinder incident investigation and remove forensic evidence. It relies on file deletion telemetry that includes the deleted filename and the process image, and it filters out deletions initiated by svchost.exe.
