What it detects

This rule flags Windows file events where the target filename contains ds7002.lnk, ds7002.pdf, or ds7002.zip. Such filename indicators can help identify phishing delivery or follow-on staging artifacts used by attackers. The detection relies on Windows file-event telemetry that includes the target filename for created/opened files.
