A robust email fraud detection system helps organizations identify and stop scams before they do significant damage. It should include layered defenses that use behavioral analytics to detect malicious attachments, unsafe URLs, and social engineering tactics. It should also have domain authentication technology like DMARC, SPF, and DKIM to prevent fraudulent domains from hijacking legitimate ones. It should also be able to scan internal emails, preventing account takeovers and other suspicious activities. And it should be able to minimize false positives, which can be inconvenient for customers and costly for businesses that must follow up on every alert.

The most common email fraud detection system vector is via email, and attackers often use a variety of techniques to trick recipients into sharing sensitive information or running malicious code. These attacks can range from simple advance-fee schemes involving fake invoices or fictitious vendors to more sophisticated business email compromise (BEC) attacks that target entire accounting departments. What all of these scams have in common is that they leverage trust in electronic communication to lower victims’ defenses and persuade them into taking actions that benefit the attacker.
