Modbus vulnerability mining method based on optimized multi-component subpackage mechanism

The invention discloses a Modbus vulnerability mining method based on an optimized multi-component subpackage mechanism, and relates to the technical field of safety of an industrial control system.The Modbus vulnerability mining method is in communication connection with equipment to be detected, and a communication network is initialized; performing protocol identification analysis based on an application layer according to the communication network; according to a protocol identification and analysis result, loading a baseline scale data packet of a corresponding protocol on the basis of the standard CVE vulnerability library, and taking the baseline scale data packet and the normal data message as a test case library; according to the method, the test case library is utilized to generate the test case, the byte position for triggering the vulnerability is positioned in the test process, and the test case generation strategy is continuously optimized on the basis, so that the test case has a better vulnera
