CEO fraud is a type of cybercrime where attackers impersonate a company's CEO or other high-ranking executives, usually via email, to deceive employees - often in finance or HR - into transferring money or sensitive information. These emails typically use social engineering tactics, urgency, and authority to pressure the recipient into bypassing standard procedures. CEO fraud is a form of business email compromise (BEC) and can result in significant financial losses and data breaches. Organizations can protect themselves by implementing strict verification processes, employee training, and multi-factor authentication.
