What is Business Email Compromise (BEC)?
Business Email Compromise (BEC) is a targeted cyber attack that uses Social Engineering and Domain Spoofing techniques to impersonate trusted individuals, such as executives or vendors, in order to manipulate victims into transferring funds or disclosing sensitive information.
Unlike traditional Phishing campaigns, BEC attacks are highly personalized and often rely on prior reconnaissance, sometimes enabled by earlier compromises such as APT activity or credential theft through Brute Force Attack methods. Attackers frequently exploit weak email security configurations, including misconfigured SPF, DKIM, or DMARC controls.
What is Business Email Compromise (BEC) used for?
BEC is primarily used for financial fraud, invoice manipulation, and unauthorized wire transfers. It can also be used to gain further access into corporate environments by harvesting credentials or sensitive communications.
Defending against BEC requires a combination of technical controls such as Email Security Gateway (ESG), user awareness training, and strong Identity and Access Management (IAM). Organizations should also monitor Indicators of Attack (IOA) and enforce verification processes for financial transactions.
