Fake CrowdStrike Falcon sensor update / channel-file remediation / EDR incident alert from non-crowdstrike.com sender

Fake CrowdStrike Falcon sensor update, channel-file remediation, or EDR incident alert from a non-crowdstrike.com sender. Following the July 2024 global CrowdStrike outage (8.5M Windows systems affected, $5.4B estimated damages), threat actors began mass-exploiting CrowdStrike brand trust — security teams who spent days responding to the outage are conditioned to immediately act on Falcon-related emails. Attackers send fake "Your Falcon sensor is out of date — update required to maintain EDR coverage" or "CrowdStrike Falcon: active threat detected — re-authenticate to the Falcon console" emails. Post-outage lures specifically reference "channel file remediation" or "Falcon sensor content update" to mimic the remediation workflow that affected IT teams had to follow manually. Enterprise security teams are high-value targets: a successfully phished SOC analyst may hand over SSO credentials to the entire security stack. The signal fires when: (1) body references CrowdStrike Falcon brand (crowdstrike, falcon sensor/agent/console/EDR) AND (2) sensor-update or incident-action urgency is present AND (3) sender is NOT crowdstrike.com AND (4) no List-Unsubscribe or In-Reply-To.
