Abstract
Techniques are described for detecting attacks that employ a display name in an email to impersonate an email sender. A computing infrastructure hosting an email security platform may determine a similarity between the display name and an email address from which the email was received. The email security platform may determine the similarity by comparing a string associated with the display name and a string associated with the sender address. The email security platform may generate a similarity value based on a result of the display name being compared with the sender address. The email security platform may determine that the email includes the display name impersonating a name of the sender, based on the similarity value meeting or exceeding a threshold value indicative of impersonation. The email security platform may delete or quarantine the email from an inbox associated with a user account.
