Abstract
Network systems, classification methods, and related apparatuses for security analyses of electronic messages are disclosed. An apparatus includes an input terminal to receive message data corresponding to an electronic message to be delivered to a destination device and processing circuitry. The processing circuitry is configured to, if the electronic message includes an attached file, disassemble the attached file to obtain assembly code from the attached file. The processing circuitry is also configured to translate the assembly code to generate function labels corresponding to functions the assembly code is configured to instruct the destination device to perform. The processing circuitry is further configured to classify the electronic message as anomalous responsive to one or more of the generated function labels being identified as suspicious.
