Ransomware gets the headlines, but Business Email Compromise (BEC) is the scam quietly costing small businesses more money, more often, with almost no malware involved. A BEC attack doesn't need to break into your systems — it just needs one convincing email that gets a bookkeeper, office manager, or business owner in Miramar or anywhere in Broward County to wire money or change a payment detail. No ransom note, no locked files — just a bank transfer that's already gone by the time anyone realizes something was wrong.
How a typical BEC scam actually works
The most common version starts with the scammer either compromising a real email account (yours or a vendor's) or registering a look-alike domain that's off by one letter from a real one. From there, they insert themselves into an ongoing conversation — often around an invoice, a wire transfer, or a payroll change — and redirect a payment to an account they control. Because the email thread looks legitimate and references real details, it bypasses the instinct that normally flags an obvious phishing attempt.
Why South Florida businesses are frequent targets
South Florida's high volume of import/export, real estate, and international business transactions makes wire transfers a routine part of daily operations here — which is exactly the environment BEC scammers look for. A wire request that would look unusual for a business that rarely moves large sums looks completely normal for a Broward County company used to paying overseas vendors or closing real estate deals.
The controls that actually stop BEC
| Control | What it stops |
|---|---|
| Callback verification for any payment/bank detail change | Redirected wire transfers — call a known number, never one from the email itself |
| Multi-factor authentication (MFA) on all email accounts | Account takeover from a stolen password |
| DMARC/SPF/DKIM email authentication | Look-alike domains and spoofed "from" addresses |
| Dual approval for wire transfers over a set amount | A single compromised employee approving a fraudulent payment alone |
| External-email warning banners | Emails impersonating an internal colleague or executive |
Not sure your business would catch a BEC attempt?
The Techie Guy sets up email authentication (DMARC/SPF/DKIM), MFA across your accounts, and a verification process for payment changes — the specific controls that stop BEC, not just generic phishing training.
Request an Email Security Review →If it already happened: what to do in the first hour
Contact your bank immediately to request a wire recall — this only works within a narrow window, so speed matters more than anything else. File a report with the FBI's IC3.gov, which can trigger a fund-recovery process for cross-border transfers. Change passwords and enable MFA on any account that may have been compromised, and review email forwarding rules, since attackers often set up a hidden auto-forward to keep monitoring the account after the initial breach.
Frequently Asked Questions
Phishing usually tries to steal credentials or install malware through a suspicious link or attachment. BEC skips both — it's social engineering aimed directly at getting a human to authorize a payment or change account details, often with no malicious link at all.
No. Since most BEC emails contain no malware or malicious links, traditional antivirus and even most spam filters won't flag them. Stopping BEC requires email authentication controls and a verification process, not just endpoint security.
Require phone callback verification — using a known, previously saved number, not one from the email — for any request to change a bank account or wire funds. This alone stops the vast majority of successful BEC attempts.
Both platforms include useful baseline protections, but the DMARC/SPF/DKIM authentication records and advanced threat settings that actually stop look-alike domains are usually not configured correctly by default and need to be set up deliberately.
Worth reviewing — many general cyber policies exclude or limit social-engineering fraud coverage unless specifically added, so it's worth confirming with your insurance broker rather than assuming it's covered.
BEC succeeds because it targets trust and routine, not technical weaknesses — which means the fix is a combination of the right email authentication settings and a verification habit your team actually follows, not just another training video.
