CEO Fraud, also known as Business Email Compromise (BEC), is a scam where the cybercriminal impersonates an internal person within an organization. For example, a criminal pretending to be the CEO can send email requests to users within the organization, aiming to initiate bank transfers, spread a Ransomware attack, or steal credentials, among other things.

Incorrect configuration of your organization's mail server can allow cybercriminals to use it to send internal emails while impersonating anyone within your organization, bypassing security controls such as SPAM filters or SPF, DKIM, and DMARC records.

Non-intrusive tests will be conducted on your domain. You may provide a port number for your mail server for the test, or the default port of the operating system will be used.
