What is Business Email Compromise (BEC)?

Business Email Compromise is a fraud method that uses fake business emails to, for example, obtain sensitive data or trigger financial transactions. Cybercriminals send emails that appear to be from employees, executives, or business partners and ask the recipient to perform certain activities for their benefit.

Business Email Compromise (BEC) stands out as a sophisticated and increasingly prevalent threat. This category of cyber attack involves a range of malicious activities that target businesses, seeking to exploit vulnerabilities within their communication and financial systems.

BEC attacks are known for their cunning tactics and the often devastating financial losses they inflict upon organizations. To better understand BEC, let’s delve into its core concept and explore the various types of attacks falling under its umbrella.

What is Business Email Compromise (BEC)?

At its core, Business Email Compromise refers to a type of cyber attack wherein threat actors manipulate email communications to deceive individuals within an organization, leading them to take actions that ultimately benefit the attackers. These actions typically involve transferring funds, divulging sensitive information, or unwittingly participating in other harmful activities. BEC attacks rely heavily on social engineering techniques, which exploit psychological triggers to manipulate human behavior.

These attacks are highly targeted and customized, often masquerading as legitimate business interactions.

Types of BEC Attacks

BEC attacks manifest in different forms, each tailored to achieve specific malicious objectives. The following are some common types of BEC attacks:

  • Impersonation of Legitimate Entities: In this scenario, attackers meticulously research their targets and gather information about the organization’s hierarchy, communication styles, and ongoing projects. They then impersonate high-ranking executives or trusted business partners, sending convincing emails that request urgent actions, such as fund transfers or confidential data sharing.
  • Social Engineering Tactics: BEC attacks leverage psychological manipulation to exploit the recipient’s trust and emotions. Attackers might forge emotional connections by impersonating family members, exploiting recent life events, or even playing on the recipient’s empathy, convincing them to take actions they wouldn’t under normal circumstances.
