In the rapidly evolving landscape of cyber threats, Business Email Compromise (BEC) has emerged as one of the most damaging and sophisticated forms of attack. This article will explore what BEC is, how these attacks are executed, and what steps businesses can take to protect themselves. 

What is Business Email Compromise? 

Business Email Compromise (BEC) is a type of cyberattack where criminals impersonate business executives or trusted partners to trick employees into transferring money or sharing sensitive information. Unlike other cyberattacks that rely on malware or brute force, BEC leverages social engineering tactics to exploit human vulnerabilities. 

How Does Business Email Compromise Happen? 

BEC attacks are often meticulously planned and executed in several stages: 

  1. Research and Reconnaissance: Attackers begin by gathering information about their target. They may monitor social media profiles, corporate websites, and other publicly available data to identify key individuals within the organization, such as executives, finance officers, or IT administrators. 
  1. Email Spoofing or Account Compromise: To make their emails appear legitimate, attackers might use email spoofing techniques or compromise a real email account within the organization. Email spoofing involves forging the sender’s address so it appears to come from a trusted source. In account compromise scenarios, attackers gain direct access to an executive’s email account, allowing them to send emails directly from the legitimate account. 
  1. Crafting the Attack Email: Once the attacker has gathered enough information and possibly compromised an account, they craft convincing emails that often contain urgent requests. These emails might ask for a wire transfer, sensitive data, or access to secure systems. The emails are designed to bypass typical suspicion by appearing to come from a known and trusted source. 
  1. Exploitation and Execution: The attacker sends the fraudulent email to the target, often someone with financial authority. The email usually contains a sense of urgency or confidentiality to pressure the recipient into acting quickly without verifying the request. 
  1. Monetization: If successful, the attacker receives the transferred funds or the sensitive information and quickly moves to launder the money or exploit the data before the fraud is detected. 

Real-World Examples of BEC Attacks 

Numerous high-profile companies have fallen victim to BEC attacks, resulting in significant financial losses. For instance, in 2016, the FBI reported that over 22,000 organizations worldwide had been targeted by BEC scams, leading to losses of over $3 billion. These attacks can affect companies of all sizes and industries, highlighting the pervasive nature of the threat. 

How to Protect Your Business from BEC Attacks 

  1. Employee Training and Awareness: Regularly train employees on how to recognize and respond to phishing attempts and BEC scams. Emphasize the importance of verifying any unusual or urgent requests, especially those involving financial transactions or sensitive information. 
  1. Implement Strong Email Security Measures: Utilize advanced email security solutions that can detect and block spoofing attempts and compromised accounts. Technologies such as DMARC (Domain-based Message Authentication, Reporting & Conformance) can help prevent attackers from impersonating your domain. 
  1. Establish Verification Protocols: Create and enforce protocols for verifying the authenticity of requests involving financial transactions. This can include multi-factor authentication, direct phone calls to verify requests, and establishing a secondary sign-off process. 
  1. Monitor Financial Transactions: Implement monitoring systems to flag unusual financial transactions. Set up alerts for large transfers or transactions to unfamiliar accounts, and ensure there is a procedure for quickly halting suspicious transactions. 
  1. Regularly Update and Patch Systems: Ensure that all software and systems are regularly updated and patched to protect against known vulnerabilities that could be exploited by attackers to gain initial access. 
  1. Use Strong Authentication Methods: Employ multi-factor authentication (MFA) for all email accounts, especially those of executives and finance personnel. MFA adds an additional layer of security by requiring a second form of verification before access is granted. 


Business Email Compromise represents a significant threat to organizations worldwide. By understanding how these attacks are carried out and implementing robust security measures, businesses can protect themselves from the potentially devastating financial and reputational damage caused by BEC. Stay vigilant, educate your team, and employ best practices to safeguard your company against this sophisticated cyber threat.
