How Hackers Trick Your Team | Email Security Essentials
Most cyber attacks don’t start with alarms going off.
They start with an email.
One that looks normal. One that feels urgent. One that asks for something simple.
And that’s how businesses lose money.
Business Email Compromise, or BEC, is one of the most common and costly types of cyber attack affecting businesses today.
It doesn’t rely on complex hacking.
It relies on trust.
What Is Business Email Compromise?
BEC is when someone impersonates a trusted contact, such as a supplier, colleague, or director, and convinces your team to:
- Transfer money
- Change bank details
- Share sensitive information
The email looks legitimate.
It often arrives at the worst possible time.
And it’s designed to make your team act quickly without questioning it.
How These Attacks Actually Happen
Most BEC attacks follow a pattern.
First, attackers gather information.
They learn how your business operates, who approves payments, and how your emails are written.
Then they either:
- Gain access to a real email account
- Or impersonate someone using a lookalike email address
Once inside, or posing as someone trusted, they wait for the right moment.
Then they send a request.
Usually something like:
“Please use these new bank details for the next payment”
“Can you process this urgently?”
“I’m in a meeting, can’t talk, just get this done”
And that’s where the risk becomes real.
Why It Works So Often
BEC works because it looks like normal business activity.
There’s no obvious warning.
No suspicious attachment.
No system failure.
It targets:
- Busy staff
- Time pressure
- Trust between colleagues and suppliers
It also sits between departments.
Finance assumes IT will block it.
IT assumes finance will question it.
Meanwhile, the payment goes through.
The Cost to Your Business
This isn’t just a technical issue.
It’s a financial one.
BEC can lead to:
- Immediate loss of funds
- Disrupted cash flow
- Time-consuming investigations
- Damaged supplier relationships
- Reputational impact
And in many cases, the money is gone before the issue is spotted.
How to Protect Your Business
The good news is this is preventable.
You don’t need complex systems. You need the right controls.
Start with this:
Never trust email alone for payments
Always verify bank detail changes using a second method, such as calling a known number.
Use approval processes
High-value or unusual payments should always require a second sign-off.
Secure your accounts
Multi-factor authentication adds an essential layer of protection.
Watch for unusual behaviour
Unexpected login activity, email forwarding rules, and strange inbox behaviour can all be early warning signs.
Train your team properly
Focus on real scenarios, not generic advice. Show them exactly what these attacks look like.
