Business e-mail compromise (BEC) is rapidly becoming one of the most serious cyberthreats that businesses face. Although these scams have been a challenge for organizations for years, the rise of advanced AI tools has made them more sophisticated and significantly more dangerous.
In 2023, BEC scams caused $6.7 billion in losses worldwide. Even more concerning, a study by Perception Point showed a 42% increase in BEC incidents in the first half of 2024 compared to the same period the previous year. As cybercriminals continue to use AI to enhance their methods, this trend is expected to grow.
What Are Business E-mail Compromise (BEC) Attacks?
BEC scams are not typical phishing attempts. They are highly targeted cyberattacks where criminals exploit e-mail accounts to deceive employees, partners, or clients into revealing sensitive information or transferring money. Unlike generic phishing, BEC scams often involve impersonating trusted individuals or organizations, making them much more convincing and effective.
Why Are BEC Attacks So Dangerous?
BEC scams are particularly successful because they manipulate human trust rather than relying on malware or attachments that can often be detected by security filters. Their impact includes:
- Severe Financial Losses: A single convincing e-mail can lead to unauthorized payments or data theft. The average loss per attack is over $137,000, and recovering stolen funds is very difficult.
- Operational Disruption: An attack can halt business operations, causing downtime, audits, and internal confusion.
- Reputational Damage: Organizations must face the challenge of explaining to clients that their sensitive data might have been compromised.
- Loss of Trust: Employees may feel less secure knowing their company was vulnerable.
Common BEC Scams To Watch Out For
BEC scams come in various forms. Some of the most common include:
- Fake Invoices: Cybercriminals impersonate vendors and send realistic invoices requesting payment.
- CEO Fraud: Hackers pretend to be executives, pressuring employees to transfer funds quickly.
- Compromised E-mail Accounts: Legitimate accounts are hacked and used to send fraudulent requests.
- Third-Party Vendor Impersonation: Trusted vendors are spoofed to make fraudulent requests seem routine.
How To Protect Your Business From BEC
The good news is that BEC scams can be prevented with the right strategies:
Train Your Team Like It's Game Day
- Teach employees how to recognize phishing e-mails, especially those labeled "urgent."
- Require verbal confirmation for any financial requests.
Enforce Multifactor Authentication (MFA)
- MFA provides an additional layer of security, even if a password is compromised. Enable it on all accounts, particularly e-mail and financial systems.
Test Your Backups
- Regularly restore data from backups to ensure they are functional. Faulty backups during an attack can severely damage your business.
Get Serious About E-mail Security
- Use advanced e-mail filters to block malicious links and attachments.
- Regularly audit access permissions and immediately revoke access for former employees.
Verify Financial Transactions
- Always confirm large payments or sensitive requests through a separate communication channel, such as a phone call.
