Classification: CPC H  G | IPC G  H

Claim 7:
8. A system for detecting a social engineering attack, comprising:
a processor; and
a memory device storing a plurality of instructions which, when executed by the processor, cause the processor to:
receive a source message;
extract an initial attribute from the source message to present a pre-processed version of the source message;
determine whether the extracted initial attribute comprises a special feature so as to generate a lexical feature vector;
tokenize 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 a suspicious topic, generate 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, apply a model to predict a risk score for the source message; and
upon the risk score exceeding a risk threshold, classify the source message as a social engineering attack.
