Attack script generation method based on finite state automaton and related device

The invention provides an attack script generation method based on a finite state automaton and a related device. The method comprises the steps: extracting an attack data stream of an attack target program and a feedback data stream of the target program responding to the attack data stream; gradually sending an attack data stream to a target program running in the virtual running environment, and receiving a response data stream generated by the target program in response to the attack data stream; when difference data between any response data stream and the corresponding feedback data stream is null, or the difference data is not null, and memory segment base addresses and offsets corresponding to values of memory address variables in the difference data are determined, generating a state transition function of this time, and updating the state transition function to the finite state automaton; If the updated state representation of the finite state automaton successfully attacks the target program, gener
