5. 24-Hour & 7-Day Action Plan
- 24-Hour Action: Immediately deploy Sigma rules and block identified '.googlegroups.com/g/u/' subfolders.
- 7-Day Remediation: Enforce FIDO2-compliant MFA (Hardware Keys) to neutralize high-fidelity session-token theft risks.
- Strategic Audit: Review conditional access logs for anomalous browser behavior originating from AppData directories.
