BEC: The Cyberattack That’s Costing Companies Billions

Written by Fernando Perez | Mar 25, 2025 2:50:00 PM

Cybercriminals aren’t just hacking systems anymore—they’re hacking trust.

Business Email Compromise (BEC) scams are rapidly becoming one of the most damaging cyberthreats for businesses worldwide. With the rise of AI-powered phishing attacks, these scams have evolved from basic email fraud into highly sophisticated, nearly undetectable cyberattacks.

📉 The Numbers Don’t Lie:

  • $6.7 billion lost to BEC scams in 2023
  • 42% increase in BEC incidents in early 2024
  • $137,000+ average loss per attack

If your business relies on email for financial transactions, vendor communications, or sensitive data exchange, you could be at risk. Here’s how BEC works and how to stop it.

What Is Business Email Compromise (BEC)?

Unlike traditional phishing, BEC scams don’t rely on malware or attachments. Instead, hackers use social engineering to impersonate trusted contacts—like your CEO, accountant, or vendors—tricking employees into transferring money or sharing confidential data.

🚨 Common BEC Attack Types:

  • Fake Invoices: Hackers pose as vendors and request urgent payments.
  • CEO Fraud: Attackers impersonate executives, instructing employees to wire funds.
  • Compromised Email Accounts: Hackers take over real accounts and send fraudulent requests.
  • Vendor Impersonation: Fraudsters mimic third-party partners to request payments or data.

💡 Trending Alert: AI is making fake emails more realistic than ever. Cybercriminals use ChatGPT-like tools to create perfectly worded phishing emails with zero typos, making them harder to spot.

Why BEC Scams Are More Dangerous Than Ever

  • They Bypass Security Filters – Since BEC emails don’t contain malware, traditional cybersecurity tools often fail to detect them.
  • They Exploit Human Trust – Employees assume they’re dealing with someone they know, making them more likely to comply.
  • They Cause Massive Financial LossesRecovering stolen funds is nearly impossible. Once the money is gone, it’s gone.

Example: The $100M Scandal

Just last year, a multinational company lost $100 million in a BEC attack after cybercriminals impersonated a well-known vendor and convinced employees to send multiple large payments. Could your business spot this scam before it’s too late?

How to Protect Your Business from BEC Attacks

Train Your Team Like It’s Game Day

  • Teach employees to verify requests before transferring money.
  • Beware of "urgent" or last-minute payment changes.

Enforce Multifactor Authentication (MFA)

  • MFA stops hackers from accessing accounts even if passwords are stolen.
  • Enable it for email, financial platforms, and cloud accounts.

Test Your Backups Before You Need Them

  • Can you recover data after a cyberattack? Test your backups regularly.
  • Ensure backups aren’t stored in the same location as live data (to avoid ransomware encryption).

Get Serious About Email Security

  • Use advanced email filters to detect AI-generated phishing emails.
  • Restrict who can send external payment requests in your organization.

Always Verify Financial Transactions

  • Call the sender to confirm any payment request—even if it looks legitimate.
  • Have a clear payment approval process that requires multiple sign-offs.
