BEC Invoice Fraud

Compromised vendor account tries to reroute payment, blocked by policy.


How the Scam Works

  • Attackers compromise a vendor's email account or spoof their domain.
  • They send an invoice that looks legitimate, often referencing real projects.
  • The email notifies you of a 'new bank account' for payment due to an audit or banking change.

Red Flags

  • Unexpected changes to payment details.
  • Emails coming from slightly different domains (e.g., vendor-billing.com instead of vendor.com).
  • Urgent requests to process payment before a deadline.

Prevention Steps

  • Verify any payment change request by calling the vendor on a known, trusted number.
  • Implement dual-approval processes for all wire transfers.
  • Train AP staff to recognize BEC indicators.

What to do if you paid
