Protecting Corporate Leaders from Targeted Business Email Compromise Attacks
Business Email Compromises (BEC) are one of the most damaging forms of social engineering attacks impacting organizations across Canada today. Most of the time they target businesses and individuals who are responsible for financial transactions. Over the past few years, BEC fraud has caused significant financial losses, threatening the credibility and operational continuity of companies worldwide.

Understanding Business Email Compromise (BEC) and Its Growing Threat
What is BEC and how does it work?
Microsoft defines business email compromise (BEC) as “a type of cybercrime where the scammer uses email to trick someone into sending money or divulging confidential company information.”
BEC can include phishing, email spoofing, impersonation, and vendor fraud. In these cases, attackers may gain access to corporate emails through targeted phishing campaigns or by purchasing compromised credentials on the dark web. Once inside, they can cause irreparable damage to internal communications, protocols, payment processes and much more. By the time they decide the launch of their attack, they will have a good understanding of exactly when and how to manipulate the organization for maximum impact.
Why BEC is More Effective Than Traditional Phishing
Unlike traditional phishing attacks that rely on malicious links or attachments, BEC takes social engineering a step further by focusing on deep psychological manipulation. Without the usual red flags, standard email security filters often fail to catch these scams. BEC attacks feel personal and authentic, addressing recipients by name and mimicking corporate communication styles to create a false sense of trust.

Real-World Impact
Even larger multinational technology enterprises such as Facebook and Google are not immune from BEC attacks. Did you know that they were the victims of an elaborate phishing attack that saw their employees send over $100 million US dollars to bank accounts overseas?
Why Executives & Financial Leaders Are Primary Targets
Cybercriminals love to target executives like CEOs, CFOs, COOs because they have direct access to financial systems, confidential data, and decision-making authority. By impersonating or compromising these executives, hackers can manipulate employees, authorize fraudulent transactions, or gain entry to valuable corporate resources.
Because executives hold more access rights within an organization, their accounts are not only attractive but also highly impactful when compromised. If an attacker successfully impersonates a CEO, for example, employees are more likely to follow urgent instructions without question.
This increasing focus on high-level targets makes executive cybersecurity a top priority. Companies must implement advanced security measures, such as multi-factor authentication (MFA), real-time email security filters, employee awareness training, and AI-driven anomaly detection to prevent these threats.

How to Prevent BEC: Policies, Technology & Verification Measures
To prevent the compromise of your emails, corporate leaders must adopt a multi-faceted solution that combines security policies, technological safeguards, and verification measures.
Learn how IT MSSPs handle cybersecurity threats.
Email Authentication & DMARC Implementation:
Start with email authentication protocols like SPF, DKIM, and DMARC to detect and block spoofed emails before they even reach your inbox. A well-implemented DMARC policy ensures that fraudulent emails masquerading as legitimate communications are flagged and quarantined, reducing the risk of impersonation.
- Multi-Factor Authentication (MFA) for High-Value Transactions: Every high-value transaction should be subjected to multi-factor authentication (MFA) to add an additional layer of verification, ensuring that even if an email account is compromised, unauthorized transfers can be halted.
- Employee Awareness Training & Simulated Phishing Tests: Human error remains one of the weakest links in cybersecurity. Regular employee awareness training and simulated phishing tests can educate employees on recognizing and reporting BEC attempts, significantly reducing the threats posed by these scams.
- Real-Time Payment Verification Policies: Implementing real-time payment verification policies can prevent unauthorized transactions. This approach involves requiring verbal confirmation or multi-user approval for wire transfers, adding a crucial layer of security.
How to Protect Your Accounts
As mentioned earlier, hackers know that CEOs, CFOs, and other senior leaders have the authority to approve transactions and access confidential information, making their accounts especially valuable. Let’s explore how you can protect your accounts.
- Executive Spoofing & Account Takeover (ATO): Attackers can hijack an executive’s email account or convincingly impersonate them to trick employees into transferring funds or sharing sensitive data. Since the request appears to come from a trusted leader, employees often act quickly without questioning its legitimacy, which can lead to significant financial losses.
- Securing Executive Communications: To keep executive emails safe, organizations must implement strong security measures like encrypted email communication and robust access controls. High-ranking officials should also use dedicated secure email portals to minimize risk.
- How DNSnetworks’ Solutions Can Safeguard Leaders: DNSnetworks provides the latest cybersecurity solutions, including email security monitoring, phishing protection, and real-time threat intelligence. By analyzing email patterns and identifying anomalies, DNSnetworks helps prevent BEC attacks before they escalate.
- The Role of Cyber Insurance in BEC Protection: While strong security measures are critical, cyber insurance can provide you with additional security, helping businesses recover financial losses caused by successful BEC attacks.

Implementing a Strong Cybersecurity Framework to Combat BEC
A strong cybersecurity strategy goes beyond just preventing attacks—it ensures an organization can quickly detect and respond to threats before they cause damage.
- Zero-Trust Security Model: Instead of assuming trust, a zero-trust approach requires continuous verification for every user and device, reducing insider threats and unauthorized access to sensitive data.
- Incident Response & Recovery Planning: No security system is foolproof. A well-prepared incident response plan ensures that if a breach occurs, the organization can act swiftly to contain and mitigate the damage. Regular drills, clear communication protocols, and predefined recovery steps are key to minimizing disruption.
- Vendor & Supplier Email Security: Cybercriminals often exploit weak links in the supply chain. Ensuring that third-party vendors follow strict security protocols, including email authentication and risk assessments, can prevent BEC attacks from infiltrating through external partners.
