    Attacker's goals: Adversaries may abuse email forwarding rules to monitor the activities of a victim, steal information, and further gain intelligence on the victim or the victim's organization to use as part of further exploits or operations. Furthermore, email forwarding rules can allow adversaries to maintain persistent access to victim's emails even after compromised credentials are reset by administrators.
    Investigative actions: Check if the identity intended to preform this action, * and look for signs that the user account and mailbox are compromised (e.g. abnormal logins, unusual activity). Check if the forwarding domain is an unknown external domain and look up its reputation. Follow further actions done by the account.
