Phishing and invoice fraud: the checks that stop most losses

Invoice redirection and impersonation scams have been a constant theme since 2022. The good news is that a small set of controls reduces the risk dramatically.

Controls that matter most

  • MFA everywhere, especially for email and finance users.
  • Email authentication using SPF, DKIM, and DMARC to reduce spoofing.
  • Payment change process that requires verification using a known phone number.
  • Mailbox rule monitoring to catch hidden forwarding rules.
  • Security awareness focused on real examples your staff see.

The process change that stops a lot of fraud

Any change to bank details should be verified out-of-band. Not by replying to the email. Not by using a number in the email signature. Use a number you already have on file.

We can review email security, tighten sign-in policies, and implement a simple invoice verification workflow.
