Email is one of the most essential tools for SME communication. However, it also presents a significant vulnerability. One of the most dangerous threats is BEC, particularly the variant known as CEO fraud. Understanding and preventing BEC is crucial for safeguarding your business from financial and reputational damage. In this article, we will explore what BEC and CEO fraudulence are, how these scams typically unfold, and what measures you can take to protect your organisation.
What is Business Email Compromise (BEC)?
BEC is a type of cyber-attack that targets companies and organisations of all sizes. The goal is to deceive employees into transferring money or sensitive data to the attackers. BEC schemes typically involve sophisticated social engineering tactics where the attacker impersonates a high-ranking executive (often the CEO), a trusted partner, or a supplier.
Understanding CEO Fraud
CEO fraudulence, a subset of business email compromise, specifically involves cybercriminals impersonating a CEO or other senior executives. The attackers use this impersonation to trick employees, usually those in finance or human resources, into executing unauthorised money transfers or disclosing confidential information. CEO fraudulence is particularly effective because it exploits the trust and authority associated with executive positions.
How Does CEO Fraud Work?
CEO fraudulence attacks are meticulously planned and executed. Here’s a step-by-step breakdown of a typical attack:
Research and Reconnaissance: Attackers start by gathering information about the target organisation. They use public sources such as company websites, social media profiles, and press releases to identify key executives and understand the company’s internal structure and processes.
Email Spoofing or Account Compromise: The attacker either spoofs (ie imitates) the email address of the CEO (making an email appear as if it’s coming from the CEO) or gains access to the CEO’s actual email account through phishing or other means.
Crafting the Email: The attacker composes a convincing email that appears to be from the CEO. The message often conveys a sense of urgency and confidentiality, instructing the recipient to transfer funds or share sensitive information immediately.
Exploiting Trust: The recipient, believing the email is genuine, complies with the instructions without verifying the request through other channels. This trust is the cornerstone of CEO fraud’s effectiveness.
Executing the Fraud: Once the funds are transferred or the information is shared, it’s usually too late to recover the assets. The attacker quickly moves the funds to accounts that are difficult to trace.
Real-World Examples of CEO Fraud
Facebook and Google: $121m BEC scam
Facebook and Google: $121 Million BEC Scam Even tech giants like Facebook and Google have fallen prey to BEC scams. Evaldas Rimasauskas allegedly impersonated an outside vendor by emailing staffers and requesting payment with convincing-looking invoices. After the companies sent urgent wire transfers, he transferred the funds to various bank accounts worldwide.

$37,560 Stolen from an Australian SMB An Australian small business lost $37,560 in a redirect fraud attack. The business owner, Jane Fleming, transferred the funds into a scammer’s bank account, thinking she was paying a legitimate subcontractor. Fleming fell for a common B2B payment fraud attack where scammers send a seemingly legitimate invoice claiming that a supplier’s bank account details have changed. A hacker presumably gained access to either Fleming’s or the subcontractor’s email account to simulate the invoice.
Preventing CEO fraud
Preventing CEO fraud requires a combination of technological solutions, employee training, and robust processes. Here are some effective strategies:
Email Authentication Technologies: Implement technologies like DMARC (Domain-based Message Authentication, Reporting, and Conformance), SPF (Sender Policy Framework), and DKIM (DomainKeys Identified Mail) to help prevent email spoofing.
Multi-Factor Authentication (MFA): Use MFA for email accounts, especially for executives and employees involved in financial transactions. MFA adds an extra layer of security, making it harder for attackers to gain access even if they obtain login credentials.
Employee Training and Awareness: Conduct regular training sessions to educate employees about the signs of BEC and CEO fraud. Simulate phishing attacks to test their awareness and response to suspicious emails.
Verification Procedures: Establish clear procedures for verifying requests for financial transactions or sensitive information. Encourage employees to verify such requests through a secondary communication channel, such as a phone call to the requester.
Implement Robust Financial Controls: Use dual authorisation for significant transactions, ensuring that no single individual can approve large transfers independently. Implement spending limits and monitor transactions closely.
Regular Security Audits: Conduct regular audits of email systems and financial processes to identify vulnerabilities and improve security measures continuously.
Incident Response Plan: Develop and maintain a comprehensive incident response plan that outlines steps to take if a BEC or CEO fraudulence attempt is detected. Ensure all employees are familiar with the plan and their roles in it.
Detecting and Responding to CEO Fraud
Despite the best preventive measures, it’s crucial to be prepared for the possibility of a successful BEC attempt. Early detection and swift response can mitigate the damage.
Monitor Email Traffic: Use advanced email filtering and monitoring tools to detect unusual patterns or signs of compromise in email traffic.
Flag Suspicious Requests: Implement systems to flag emails that contain urgent requests for financial transactions or sensitive data, especially if they deviate from normal business practices.
Rapid Response Protocols: Have clear protocols for responding to suspected BEC incidents, including immediate notification of IT and financial departments, freezing suspicious transactions, and contacting relevant financial institutions.
Legal and Regulatory Compliance: Ensure compliance with legal and regulatory requirements for reporting cyber incidents. This can help in coordinating a response and potentially recovering lost assets.
Business Email Compromise, and particularly CEO fraud, pose significant threats to organisations of all sizes. These attacks exploit human trust and the authority of executive positions to perpetrate financial fraud and steal sensitive information. By understanding the anatomy of these scams and implementing robust preventive measures, organisations can significantly reduce their risk.
Investing in advanced email security technologies, training employees, and establishing rigorous verification and financial control procedures are critical steps in defending against BEC. Additionally, having an effective incident response plan ensures that any breach is swiftly contained and mitigated.
As cyber threats continue to evolve, so must our strategies to combat them. By staying informed and proactive, businesses can protect themselves from the potentially devastating impacts of Business Email Compromise and CEO fraud, ensuring their operations and reputations remain intact in an increasingly digital world.
