BEC is a type of fraud where attackers impersonate executives or suppliers to trick employees into transferring funds or sharing sensitive data. BEC attacks increased 33% in 2025. The average loss per BEC incident is $137,000. Even organisations with fewer than 1,000 employees face a 70% weekly probability of a BEC attempt.
