Abstract

An email is received that is from an email sender. From the email, the display name of the email sender, an email address of the email sender, and an email domain of the email sender, is extracted. A score is determined for the email based on at least: the extracted display name of the email sender, the extracted email address of the email sender, and the extracted email domain of the email sender, where the score indicates a probability that the email is from a legitimate sender. Message content of the email is input into multiple classifiers each corresponding to a particular message type. The message type of the email is determined based on output of the classifiers. Based on at least the determined score for the email and the determined message type of the email, a determination is made whether the email is associated with a BEC attack.
