Business Email Compromise: The Scam That’s Costing Businesses Millions

Cybercriminals are no longer just targeting giant corporations. Small and mid-sized businesses across the country are being hit every day by a growing threat called Business Email Compromise (BEC). For many companies, it only takes one fake email, one rushed payment, or one employee trusting the wrong message to create a financial disaster.

At GingerSec, we’ve seen businesses become targets simply because attackers know employees are busy, distracted, and constantly communicating through email.

What Is Business Email Compromise?

Business Email Compromise is a type of cyberattack where criminals impersonate a trusted person or company through email. Their goal is usually to trick someone into:

• Sending money

• Changing banking information

• Purchasing gift cards

• Sharing sensitive company data

• Resetting passwords or account access

Unlike traditional phishing emails full of spelling errors and obvious scams, BEC attacks are often highly convincing. Attackers study companies, employees, vendors, and executives before launching the attack.

The email may appear to come from:

• The company owner

• A manager or supervisor

• A vendor

• A customer

• An accountant

• A shipping provider

• Even Microsoft 365 or Google Workspace

How These Attacks Usually Happen

A typical Business Email Compromise attack looks something like this:

Your accounting employee receives an email from what appears to be the company owner.

“Hey, I’m in meetings all afternoon. Can you wire this payment before 3 PM?”

The email looks legitimate. The name matches. The signature looks real. Maybe the attacker even copied previous email formatting from a compromised account.

The employee sends the payment.

Thirty minutes later, the business realizes the money went directly to a criminal account.

At that point, recovery becomes difficult — and sometimes impossible.

Why Small Businesses Are Prime Targets

Many small businesses believe attackers only care about large corporations. Unfortunately, the opposite is often true.

Smaller organizations typically:

• Have fewer cybersecurity protections

• Lack formal approval processes

• Use shared passwords

• Depend heavily on email communication

• Trust employees to “just handle it quickly”

Attackers know this.

They also know that many businesses operate fast. When someone sees an urgent email from a boss, vendor, or customer, they often react before verifying the request.

Common Warning Signs

Business Email Compromise emails often include:

• Urgent requests

• Pressure to act quickly

• Requests to keep things confidential

• Slightly altered email addresses

• Last-minute banking changes

• Unexpected invoices

• Requests for gift cards or wire transfers

One of the biggest red flags is urgency.

Attackers want people rushing instead of verifying.

Real-World Example

A company receives a message from a vendor they’ve worked with for years.

The email says:

“We recently changed banks. Please update our ACH information for future invoices.”

Everything looks normal.

The next invoice gets paid.

Except the vendor never sent the message.

The payment disappears into a fraudulent account, and the business still owes the original invoice to the real vendor.

Now they’re paying twice.

How Businesses Can Protect Themselves

The good news is that Business Email Compromise is preventable when businesses put the right processes in place.

1. Enable Multi-Factor Authentication (MFA)

MFA adds an extra layer of protection to email accounts and dramatically reduces the risk of compromised accounts.

2. Verify Financial Requests

Never trust email alone for:

• Wire transfers

• Banking changes

• Gift card purchases

• Payroll updates

Always verify requests through:

• A phone call

• Microsoft Teams

• An in-person conversation

• A known contact method

3. Train Employees Regularly

Cybersecurity awareness training is critical. Employees should understand:

• Phishing tactics

• Fake login pages

• Spoofed email addresses

• Social engineering techniques

4. Use Email Security Protection

Advanced email filtering can block:

• Impersonation attempts

• Malicious links

• Suspicious attachments

• Domain spoofing

5. Create Internal Approval Policies

Require multiple approvals for:

• Large payments

• Vendor banking changes

• Payroll modifications

• Financial transfers

Even a simple two-person verification policy can stop many attacks.

The Biggest Mistake Businesses Make

The most dangerous phrase in cybersecurity is:

“That would never happen to us.”

Attackers don’t need to hack an entire company network if they can simply convince one employee to click, reply, or send money.

Business Email Compromise attacks work because they exploit trust — not just technology.

Final Thoughts

Cybercriminals are becoming smarter, faster, and more convincing. Business Email Compromise attacks are now one of the most financially damaging cyber threats facing businesses today.

The companies that avoid becoming victims are usually the ones that:

• Train employees

• Verify requests

• Use proper security protections

• Take cybersecurity seriously before an incident happens

At GingerSec, we help businesses strengthen email security, improve employee awareness, and reduce the risk of costly cyber incidents before they happen.

Because one fake email should never be able to shut down a business.
