Business Email Compromise (BEC) fraud is a sophisticated scam targeting businesses and organizations worldwide. It involves criminals impersonating executives, vendors, or trusted partners to trick employees into transferring funds or sharing sensitive information. According to the FBI, BEC scams have caused billions in losses globally. Here’s a detailed guide from INTCIPOL to help you understand and protect against this growing threat.
What is Business Email Compromise (BEC) Fraud?
BEC fraud is a type of cybercrime where attackers gain access to or spoof business email accounts to deceive employees into:
- Transferring money to fraudulent accounts.
- Sharing confidential company information.
- Changing payment details for vendors or suppliers.
These scams often rely on social engineering, exploiting trust and urgency to manipulate victims.
How BEC Fraud Works
- Reconnaissance: Criminals research the target organization, identifying key employees, vendors, and financial processes.
- Spoofing or Hacking: They either:
- Spoof an executive’s email address (e.g., CEO@yourcompany.com) to make it appear legitimate.
- Hack into an executive’s or vendor’s email account to send fraudulent requests.
- The Request: The attacker sends an email, often marked as urgent, instructing the recipient to:
- Wire funds to a new account.
- Update payment details for a vendor.
- Share sensitive data like payroll information or tax records.
- The Payoff: Funds are transferred to the criminal’s account, often overseas, making recovery difficult.
Common Types of BEC Scams
- CEO Fraud: Attackers impersonate a high-ranking executive and request urgent wire transfers.
- Vendor Fraud: Criminals pose as a trusted supplier and request payment to a new account.
- Account Compromise: An employee’s email account is hacked and used to send fraudulent invoices or requests.
- Legal Impersonation: Scammers pretend to be lawyers or legal representatives handling confidential matters.
