Claim 0:
1. A computer-implemented method, comprising:
receiving, by a host, a source message;
extracting, by the host, an initial attribute from the source message to present a pre-processed version of the source message;
determining, by the host, whether the extracted initial attribute comprises a special feature so as to generate a lexical feature vector;
tokenizing, by the host, the pre-processed version of the source message to generate a cleaned token list comprising a plurality of tokens;
based on determining whether the cleaned token list includes one or more suspicious topics, generating, by the host, a topics vector and a correlation score for each token of the plurality of tokens in the cleaned token list;
based on the lexical feature vector and the topics vector, applying, by the host, a model to predict a risk score for the source message; and
upon the risk score exceeding a risk threshold, classifying the source message as a social engineering attack.
