Question 470
The SOC deletes a malicious mailbox rule but ignores active sessions on the compromised account. Which action most directly addresses the observed condition?
Explanation
Correct Answer
Removing the rule alone does not close an active attacker session. This directly addresses the requirement to contain mailbox compromise beyond the rule.
Incorrect Answers
Malicious forwarding rules are a common persistence and data theft mechanism in compromised mailboxes. This addresses remove mailbox forwarding persistence; it does not directly satisfy contain mailbox compromise beyond the rule.
Mailbox and identity logs reconstruct rule creation and associated account access. That action focuses on attribute a suspicious inbox rule rather than the specified need to contain mailbox compromise beyond the rule.
Change context separates routine routing from newly introduced suspicious destinations. This addresses identify unauthorized forwarding changes; it does not directly satisfy contain mailbox compromise beyond the rule.
