Business email compromise is a specific corollary of phishing. It’s a heightened level of deception that involves impersonation, as the attacker uses artificial intelligence to create behavioral profiles of key executives and mimic email behavior.
An employee will receive an email that asks for sensitive information like a request to switch account numbers, or to move funds from one bank to another. However, the attacker will make the email look as though it came directly from a C-level executive, which is why these attacks have also become known as CEO fraud.
