Answer: Sync email accounts settings.
Explanation: This attack abuses mailbox rules/auto‑forwarding. Centralized management or syncing of account/mailbox settings (and disabling/monitoring automatic external forwarding, enforcing DLP/forwarding policies, enabling mailbox auditing and alerts, and requiring MFA) prevents or detects unauthorized forwarding. The other options (blocking ICMP, screening “signatures” in emails, or extracting kernel memory dumps) do not address mailbox auto‑forward rules.
