What is BEC?

What is BEC?

What is BEC?
Business email compromise (BEC) is one of the fastest-growing forms of cybercrime. With more than half of all global businesses using Microsoft 365, criminal groups have a vast and growing list of potential targets, using methods ranging from phishing and social engineering to credentials leaked in data breaches.
Once inside an account, threat actors can send malicious emails, facilitate fraudulent transactions, and collect personal data for use in identity theft or fraud.
