Engineer — Learn: A useful framing of why session-theft, malicious extensions, and in-browser manipulation leave no classic EDR artifacts — informs decisions about adding browser isolation or enterprise browser controls to the defense stack, but no immediate patch or config action required.
SOC/IR — Plan: The coverage gaps described (no process creation, no file writes for browser-based session theft) are worth addressing this quarter by evaluating browser telemetry sources — proxy logs, enterprise browser audit events, or identity provider anomaly detection — to compensate for what EDR won’t surface.
