Sample question 1 — Security Operations
An employee forwards a suspicious email to the security team. The message asks recipients to sign in through a link that mimics the company portal. Several coworkers already clicked the link. Which action should the team take first?
- A. Block the link and reset credentials for everyone who clicked it, then notify affected staff
- B. Reply to the original email telling all recipients that the message is a scam and to be careful
- C. Wait for the email gateway vendor to release a signature update before taking any other action
- D. Delete the forwarded message from the security mailbox so it cannot be clicked again by analysts
Answer: A. Option A is correct because blocking the malicious link stops further clicks while resetting credentials for those who clicked contains any stolen sessions or passwords, and notification supports awareness. Option B is incorrect because replying to the original message reaches only that thread and does not invalidate credentials already entered. Option C is incorrect because waiting for a vendor signature leaves the link live and the exposed accounts unprotected. Option D is incorrect because deleting the forwarded copy removes evidence and does nothing about the active link or compromised credentials.
