Detection of synthetic text in emails in an organization inbound email traffic

Abstract

A computer-implemented method of detecting synthetic text in an email may determine whether the sender of a received email is a named individual and if so, may extract textual content from the email. When the size of the extracted textual content is at least equal to a configurable size threshold, the extracted textual content may be analyzed using a plurality of synthetic text detection engines, each being configured to generate a synthetic text detection score. The synthetic text detection scores may then be compared to a respective score threshold associated with each of the synthetic text detection engines. An action to warn and/or protect the recipient of the email may be carried out when one or more synthetic text detection scores is at least equal to a respective associated score threshold, which is indicative of a detection of synthetic textual content in the received email.
