Business Email Compromise Explained
I have worked in the UK Financial services industry for over 25 years and seen attacks from the likes of Wannacry in 2017 to modern spear phishing with AI in 2025. All of them are scary and all have the potential to end a business. In an increasingly digital world, one of the most damaging threats to businesses isn’t something as mainstream as Wannacry but something far quieter and far more deceptive: CEO fraud. You may also have heard of this as business email compromise (BEC). CEO fraud involves cybercriminals impersonating company executives or trusted partners to trick employees into wiring funds, disclosing sensitive data, or bypassing standard controls. In a world of AI with deep fake videos this is getting harder and harder to protect against.
For senior executives in companies, especially CEOs in the UK and USA, understanding this threat is now mission-critical. The risk isn’t just for big business either. Cyber criminals can work efficiently now using AI that they are looking at businesses of all sizes. Small and large. Companies of all sizes have been financially devastated by acceptable-looking but fraudulent payment requests, and sophisticated scammers are only getting smarter.
What Is CEO Fraud and How Does It Work?
At its core, CEO fraud is a form of social engineering. Attackers manipulate human trust rather than technical vulnerabilities. So no matter how good your firewall it won’t help you. Instead of exploiting software bugs, they exploit human psychology: authority, urgency, and familiarity.
Here’s how a typical CEO fraud attack unfolds:
Reconnaissance: Scammers gather information about your organisation, often from public sources like LinkedIn, company websites, or social media. They build a credible profile of executives and employees. Your profile is more visible than you probably realise and this information is what they use to build a profile of you.
Impersonation: Using this information, attackers create fake email addresses or compromised accounts that look almost identical to real ones. These could be email spoofing, look-alike domains (e.g., ceo@company-ltd.com instead of ceo@company.com), or even voice and video deepfakes. These can be rich in detail having mined anything on you they can find.
Urgent Request: The scam usually involves a fabricated crisis or opportunity. “Urgent payment needed for a confidential acquisition” or “transfer funds for legal fees.” The message is crafted to pressure the recipient into acting without verifying.
Bank Transfer: A trusted employee, often in finance or accounts payable, follows the instruction and transfers funds to a scammer’s account. Sometimes the fraud continues with multiple transfers before anyone realises.
Unlike brute-force hacks, these attacks can be invisible to anti-virus tools or firewalls because they don’t involve suspicious software. They exploit trust. They leverage the human connections in your business. I have seen it happen and put in place the controls to try and protect businesses from this.
Why Employees Fall for It
Even well-trained teams can be fooled. There are several reasons why:
Authority Bias: Employees are taught to respect and obey executives. When an email appears to come from the CEO or CFO, many workers assume it’s legitimate without additional verification.
Urgency Exploitation: Scammers craft messages that demand immediate action — “This must be processed before end of day.” The pressure pushes employees to skip verification steps.
Realism: Today’s spoofing techniques are more convincing than ever. Fake emails can carry correct logos, employee names, and even match writing style. In some recent cases, AI-driven deepfake audio was used to impersonate executive voices.
Routine Expectations: Finance teams process wire transfers every day. Scammers exploit this routine, blending fraudulent requests into normal operational flow.
High-Profile CEO Fraud Incidents
Here are real world recent incidents that show just how severe and varied CEO fraud can be:
Arup Group Hit £25m Loss
Global consultancy Arup reported a cyberattack in 2024 that cost over £25 million after criminals used fake voices, images, and signatures to trick staff into transferring funds to fraudulent accounts. Arup’s leadership described it as a sophisticated targeted fraud that slipped past normal defences.
€50m Loss for FACC from CEO Fraud
Austrian aerospace firm FACC lost between €42 million and €50 million when attackers impersonated its CEO via email, convincing employees to authorise international transfers. Although this happened over several years, it’s often cited as one of the largest CEO fraud episodes in Europe.
$46.7m Ubiquiti Networks Compromise
A U.S. technology company lost nearly $47 million after attackers spoofed accounts, prompting finance staff to transfer funds overseas. This is one of the most costly BEC attacks ever reported.
These cases aren’t isolated. From small councils targeted for millions to global engineering firms losing vast sums, CEO fraud affects organisations of all sizes and sectors. Don’t let your business be the next victim.
Why Traditional Cyber Security Alone Isn’t Enough
CEO fraud exploits human behaviour, not software vulnerabilities. That means traditional security tools like firewalls and endpoint protection cannot stop these attacks by themselves. Scammers rarely inject malware, they manipulate conversations between your staff. Legitimate credentials and official email addresses may be used or ones so close that people don’t notice. I have been subject to one of these attacks where the domain was spoofed changing only a single character. AI tools can craft highly personalised and convincing messages. And it is getting worse!
This is why we created CyberSentrx. A different layer of defence to alert you of vulnerabilities in your business.
What CEOs Should Do About It
For leaders in the UK and USA, tackling CEO fraud must be a board-level priority. As well as implementing CyberSentrx we recommend all our customers take steps to avoid CEO fraud. Our monthly reports on vulnerabilities include steps to protect businesses we support. Steps you can take now include:
1. Implement Multi-Factor Approval Controls - Require dual sign-off for any payment over a certain threshold, especially international transfers.
2. Educate Your Team - Regular training on spotting CEO fraud and BEC tactics isn’t optional — it’s essential.
3. Use AI-Aided Detection - Modern solutions can flag unusual patterns — like new payees, atypical amounts, or off-hours requests.
4. Verify Outside Channels - If an email demands urgent transfers, establish a policy to confirm via phone or secure messaging.
5. Simulate Scenarios - Run phishing tests and social engineering drills to strengthen awareness.
Conclusion: CEO Fraud Isn’t a Distant Threat but Here, Now
CEO fraud is no longer a fringe concern. It is a multi-billion-dollar global risk affecting sectors from engineering to technology and government services. For CEOs in the UK and USA, the lesson is clear: your employees can accidentally become conduits for fraud if you don’t combine technology, training, and verification.
