It usually starts with an email that looks completely normal. Your bookkeeper gets a message from a vendor you have paid for years: same logo, same signature, a routine invoice. The only thing different is one line, the bank account the payment should go to. She pays it, because that is her job. Two weeks later the real vendor calls asking where their money is. It’s gone, and it isn’t coming back.
What business email compromise actually is
That’s business email compromise, or BEC, and it’s the most expensive cyber threat most small businesses have never heard of. There is no virus to catch, no ransom screen. The attacker simply pretends to be someone you trust, your boss, a vendor, a client, and asks you to move money or hand over information. It works because it doesn’t attack your computer. It attacks your habits.
Why it works, and why smaller firms get hit
BEC thrives on two things every busy office runs on: authority and urgency. An email from “the CEO” marked urgent, asking to wire funds before a deadline, gets acted on fast, precisely because slowing down feels like the wrong move. And small and mid-sized firms are prime targets. Finance offices, CPA firms, and law practices move real money and hold sensitive client data, but rarely have the layered email defenses a bank would.
The scams rhyme. A “vendor” sends a new invoice with updated bank details. The “owner” asks an assistant to buy gift cards for a client. HR gets a request to reroute an employee’s direct deposit. Payroll, wire transfers, and vendor payments are the favorite targets, because that is where the money actually moves.
The one habit that stops most of it
The single most effective defense costs nothing: verify any request to move money or change payment details using a second channel. If an email asks you to wire funds or update a vendor’s bank account, pick up the phone and call the person on a number you already have, not one from the email. A thirty-second call has stopped more six-figure losses than any piece of software.
Around that habit, the technical layers matter: multi-factor authentication on every email account so a stolen password isn’t enough, email filtering that flags spoofed senders and outside messages, and short, regular security-awareness training so your team spots the play before they fall for it.
