What business email compromise means
Business email compromise happens when criminals use email to trick a business into sending money, changing bank details, sharing information or giving access. The attacker may compromise a real mailbox or impersonate a supplier, customer, manager or staff member.
The Australian Cyber Security Centre explains that protective measures can help prevent email accounts from being compromised, make impersonation harder and reduce the risk of email fraud. For small businesses, simple controls can make a major difference.
Common warning signs
- A supplier suddenly changes bank account details by email.
- An urgent payment request arrives from a manager or owner.
- Email wording feels slightly unusual but the address looks familiar.
- Invoices arrive with changed payment details.
- A staff mailbox sends messages the user did not send.
- Login alerts or MFA prompts appear unexpectedly.
- Email forwarding rules appear without explanation.
Practical prevention steps
- Use multi-factor authentication on business email accounts.
- Confirm bank detail changes by phone using a known trusted number, not the number in the email.
- Limit admin access to only people who need it.
- Review mailbox forwarding rules and sign-in activity when suspicious.
- Train staff to slow down on urgent payment requests.
- Use strong unique passwords and password managers where suitable.
- Keep recovery details current for Microsoft 365 and email accounts.
What to do if you suspect compromise
Act quickly. Stop payment if possible, contact the bank, change passwords from a clean device, revoke suspicious sessions if available, check forwarding rules, warn affected contacts and report the scam. If a computer may also be infected, it should be checked before passwords are reused.

Common Questions
Is business email compromise only a big company problem?
No. Small businesses are often targeted because payment processes may be informal.
Should bank detail changes be trusted by email?
No. Confirm using a known phone number or separate trusted method.
Does MFA help?
Yes. MFA makes account takeover harder, although users must not approve unexpected prompts.
Can you help after a suspected compromise?
Yes. OCT can help check devices and email symptoms, but banks and official reporting should be contacted quickly for payment fraud.
