Phishing and scam email defense

Verify suspicious email without letting the message choose the route

Modern phishing can be polished, authenticated, and sent from a compromised real account. A verification workflow is more dependable than a checklist of typos.

Pause before action

Evaluate identity, intent, and impact

No single clue decides the case. Start with what the sender wants, then verify the request through a channel the message did not supply.

Identity

Expand the full address, compare the reply path, review authentication context, and remember that a real account can be compromised.

Use the verification workflow →

Intent

Name the requested action: credentials, money, attachments, access, secrecy, or a switch to another channel.

Review approval controls →

Impact

Choose stronger verification as the consequence rises. Payment and recovery changes should never depend on one email.

The safest click is often no click at all

You do not need to prove that a message is malicious before refusing its route. Open the relevant app from a saved bookmark, type the known address, call a trusted number, or start a fresh conversation with the person. This separates the decision from links, phone numbers, and reply addresses controlled by the message.

Unexpected attachments should be treated as untrusted input. A familiar icon or file name does not establish safety, and password-protected archives can hide content from automated inspection. When a document is expected in a known collaboration system, open that system directly and locate it there.

Account alerts deserve visibility but not blind trust. Review security activity inside the service, deny multifactor prompts you did not initiate, and protect mailbox rules and recovery settings. Reporting quickly gives defenders a chance to block related messages and contain compromised accounts.

Verification is not an accusation. Healthy teams expect callbacks and second-channel checks for payment changes, access requests, sensitive exports, and unusual commitments.
Operating checklist

Use the same five steps every time

A repeatable routine works under pressure and can be taught across finance, support, operations, and leadership.

  • Stop before clicking, replying, calling, opening, or approving.
  • Name the action and the consequence if the request is false.
  • Switch to a trusted app, bookmark, number, or new conversation.
  • Confirm details not supplied only by the suspicious message.
  • Report through the documented channel and preserve useful evidence.
ObserveCollect the minimum evidence needed to describe the event.
VerifyUse a trusted system or independently known channel.
ConstrainLimit permissions, scope, duration, and affected recipients.
ReviewMeasure mistakes, remove stale rules, and document changes.
