Business Email Compromise (BEC) is quickly becoming one of the most dangerous cyber threats for businesses of all sizes. While these scams have been a concern for years, advanced AI tools have made them even more sophisticated – and far more dangerous.
In 2023, BEC scams caused $6.7 billion in global losses. Even more concerning, a study by Perception Point revealed a 42% increase in BEC incidents during the first half of 2024 compared to the same period the previous year. With cybercriminals using AI to fine-tune their tactics, this trend is only growing.

What Are Business E-mail Compromise (BEC) Attacks?
BEC scams are not your typical phishing attempts. They are highly targeted attacks where cybercriminals exploit email accounts to trick employees, partners, or clients into sharing sensitive information or making fraudulent payments.
Unlike generic phishing, BEC scams often involve impersonating trusted individuals or companies, making them much harder to detect and more effective.
Why BEC Scams Are So Dangerous
BEC scams are alarmingly successful because they rely on manipulating human trust rather than malware or attachments, which can often be detected by filters. Here’s what makes them so destructive:
Financial Losses
One convincing email can lead to unauthorized payments or data theft. The average loss per attack exceeds $137,000, and recovering stolen funds is nearly impossible.
Operational Disruption
A BEC attack can halt business operations, causing downtime, audits, and chaos within your organization.
Reputational Damage
How do you explain to your clients that their sensitive data was compromised?
Loss of Trust
Employees may feel less secure, knowing their organization was vulnerable to this kind of attack.
Common BEC Scams to Watch Out For
BEC scams come in various forms. Here are a few to look out for:
- Fake Invoices: Cybercriminals impersonate vendors and send realistic invoices requesting payment.
- CEO Fraud: Hackers pose as executives, pressuring employees to transfer funds urgently.
- Compromised Email Accounts: Legitimate accounts are hacked and used to send malicious requests.
- Third-Party Vendor Impersonation: Trusted vendors are spoofed to make fraudulent requests appear routine.
