Why Your Report Makes a Difference

SOC Alert

Our Security Operations Center is instantly notified of the threat.

ZAP

Zero-Hour Auto Purge removes the same threat from every CMC inbox automatically.

Firewall

Malicious links and attachments are blocked at the network level.

Defense

Trend data helps ITS proactively defend against future attacks targeting CMC.

Before You Begin

  • The suspicious email is still in your inbox (don't delete it before reporting)
  • Outlook desktop app or Outlook on the web (www.cmc.edu/mail)
  • Do NOT forward the email to anyone — use the Report button only
1

Open the Suspicious Email in Outlook

Open the email you want to report in Outlook desktop or Outlook on the web (www.cmc.edu/mail). Do not click any links or open any attachments inside the email.

2

Find the "Report Phishing" Button

The location differs slightly between Outlook versions:

  • Outlook desktop: Look in the Message tab in the ribbon at the top — find the "Report" or "Report Phishing" button
  • Outlook on the web: Look for the three-dot menu (…) or "Report Phishing" button in the email toolbar at the top of the message
3

Select "Phishing" from the Options

When you click "Report Phishing," you'll see options such as Junk, Phishing, and Not Junk. Select Phishing. This sends the full email with headers to Microsoft's security team and simultaneously notifies CMC's Security Operations Center.

4

Confirm and Delete

You'll see a brief confirmation message. After confirming the report, delete the email from your inbox and then empty your Trash/Deleted Items folder to fully remove it from your mailbox.

Common Phishing Red Flags

Urgent Language

"Your account will be closed," "Immediate action required," "Verify now or lose access"

Suspicious Sender

Email addresses that resemble CMC addresses but have subtle differences or unexpected domains

Unexpected Attachments

Especially .zip, .exe, or macro-enabled Office documents (.docm, .xlsm)

Mismatched Links

Hover over links before clicking — do they go where they claim? Mismatched URLs are a major warning sign.

Gift Card / Money Requests

"Please buy $500 in Apple gift cards and send me the codes" — a classic scam targeting students and staff

Unsolicited Job Offers

Vague job offers with high pay and minimal requirements sent via email are common phishing vectors

What NOT to Do

  • Do not click any links inside the suspicious email
  • Do not open any attachments
  • Do not reply to the sender
  • Do not forward the email to colleagues or the Help Desk — use the Report button
  • Do not ignore it — even if you think it's harmless, reporting helps protect everyone

Common Questions

Act immediately: (1) Change your CMC password at mypassword.claremontmckenna.edu right now. (2) Call the Help Desk at (909) 607-0911. (3) Do not wait or try to investigate on your own. The sooner we act, the better we can contain any damage.
Please use the Report Phishing button in Outlook instead of forwarding. The button sends the email with full technical headers to our security systems, enabling automatic Zero-Hour Auto Purge. Forwarding strips the headers we need and could expose your colleagues to the threat.
Check your Deleted Items / Trash folder — the email may still be there. If you can find it, report it using the Report button. If it's already been permanently deleted, contact the Help Desk and describe the email as best you can so we can investigate.
The button should be in the Home or Message tab of the ribbon in Outlook desktop, or in the "…" more options menu in Outlook on the web. If you still can't find it, contact the Help Desk — it may need to be enabled on your account.
