Business Email Compromise Fraud: AML Risk Signals

Certivus AML team8 minUpdated 2026-06-27

In brief: Business email compromise fraud occurs when a criminal manipulates email instructions to redirect payment, and it can create AML risk when funds move through client or business accounts.

Key points

  • BEC fraud is often a payment-instruction fraud.
  • For AML, focus on the money movement, client explanation, and whether funds have become criminal property.
  • Keep a decision note and consider internal escalation where suspicion arises.

What is business email compromise fraud?

Business email compromise fraud, often shortened to BEC fraud, involves a criminal compromising or impersonating email communications to redirect payments. Examples include fake supplier bank-detail changes, invoice interception, and impersonation of a senior employee.

Why it matters in professional work

A firm may see BEC risk when reconciling accounts, handling client money, reviewing invoices, or advising after a compromised payment. The fraud itself may be outside the firm's role, but the movement of funds can still create AML questions.

Red flags

  • Bank details change close to payment.
  • Email tone or domain is subtly different.
  • Payment urgency is unusual.
  • Invoice details do not match the supplier history.
  • Client cannot explain why funds moved through an account.

File response

Record the facts, preserve supporting documents, reassess source-of-funds risk, and escalate internally if the firm suspects criminal property.
