Key rule: verify through an official route you opened yourself, not the link, number, app, or payment details supplied by the suspicious message.

Why this scam is effective

The invoice itself may be expected, accurate, and tied to a real supplier relationship. The fraud is the bank detail change or the spoofed email that introduces it.

Treat changed details as high-risk

Any message that updates supplier payment details should trigger mandatory verification through a trusted phone number or contact path already on file.

Look for subtle email differences

The sender domain may differ by one character, use a new hyphen, or come from a reply-to address that staff are not used to checking.

Use dual approval for larger payments

A second reviewer or callback process reduces the chance that one rushed employee processes the fraud alone.

If a payment has gone out

Notify your bank and the genuine supplier immediately. Fast notification gives the best chance of intervention.

Operational defence

Create a standing rule that bank detail changes are never approved on email alone.

Frequently asked questions

Can the rest of the invoice be genuine?

Yes. Only the payment details may be fraudulent.

Is this only a large-company problem?

No. Small businesses are common targets because controls can be lighter.

Should staff call back on the number in the email?

No. Use a trusted number already on record.
