Understanding Business Email Compromise: Why Trusted Emails Still Need Verification

%20(1).png)
Business Email Compromise, or BEC, is a targeted scam in which a criminal impersonates someone you trust. They may pose as an executive, lawyer, vendor, advisor, employee, or family member and ask you to send money, change banking details, or share sensitive information.
The message may come from a lookalike email address or a real account that has been compromised. This can make the request appear normal and include details that only a trusted person would seem to know.
Executives, high-net-worth individuals and their families, and anyone able to move money or release sensitive information are valuable criminal targets. AI-written emails and voice cloning can make these scams even more convincing.
How it works
An attacker sends a message that appears to come from someone you know. It is designed to seem routine or urgent so that you act before confirming the request another way.
If a real email account has been compromised, the attacker may review conversations, invoices, contacts, and travel details. They can use this information to create a convincing request at the right time.
The risk works both ways. You may receive a fraudulent message, or your own account may be taken over and used to contact others in your name.
Why BEC is a major threat
According to the FBI Internet Crime Complaint Center’s 2025 Annual Report, BEC led to 24,768 reported complaints and more than $3 billion in reported losses in 2025. Only investment fraud caused greater reported losses that year.
BEC is also becoming harder to identify. AI can create professional messages without the spelling mistakes or awkward wording often linked to scams. Voice cloning may also make a call or voice message sound like someone you know.
Warning signs of business email compromise
Watch for:
- Urgency combined with secrecy
- New or changed payment or banking details
- A reply-to address that differs from the sender’s address
- A request that skips the normal approval process
- Pressure to move the conversation to text or WhatsApp
- An unusual request for sensitive information
A message from a compromised account may not show any of these signs. Verifying the request is more reliable than deciding whether the email looks suspicious.
How to protect yourself
Confirm every new payment instruction, banking change, or urgent transfer by calling the person directly. Use a number saved in your contacts, shown on a previous statement, or obtained from another trusted source.
Never use a number provided in the same email as the request.
During the call, confirm the payment amount, recipient, bank, account details, and reason for the transaction. Be especially careful if any information has changed.
Require approval from a second trusted person for payments above a set amount. Everyone involved should be expected to pause and verify a request, even if this causes a short delay.
Protect every email account including personal accounts, with a strong, unique password and multi-factor authentication. Keep recovery information current and check for unfamiliar forwarding rules, filters, connected applications, or signed-in devices. Do not reuse your email password on other services.
If you have been targeted
If you sent money or shared banking information, contact your financial institution immediately. Ask whether the payment can be stopped, recalled, or frozen. Keep the original emails, messages, and payment records.
If you believe your email account was compromised:
- Change the password from a trusted device.
- Sign out of other active sessions.
- Review the account’s security and recovery settings.
- Remove unfamiliar rules or connected applications.
- Notify anyone who may have received a fraudulent message from your account.
