Abstract
A method includes: accessing a corpus of emails sent from a email account prior to the initial time period; correlating sequences of words, in the corpus of emails, with language signals; aggregating the language signals into a sender model that represents combinations of language signals characteristic of language in emails sent from the email account; later, accessing a email outbound from the email account and directed to a recipient; scanning the email for the set of language signals; correlating sequences of words in the email with language signals; calculating a similarity score for the email based on the subset of language signals detected in the email and the sender model; and, in response to the similarity score falling below a threshold similarity, flagging the email as suspicious and redirecting the email away from the recipient.
