Abnormality determination method and device, storage medium and electronic device

The invention discloses an exception determination method and device, a storage medium and an electronic device.The method comprises the steps that in the process of executing a target program, an instruction jump sequence corresponding to K instructions which are continuously executed in the target program is obtained, the instruction jump sequence comprises indexes of the K instructions, and the indexes of the K instructions correspond to the indexes of the K instructions; the instructions are used for indicating the executed sequence of the K instructions, and K is an integer greater than 2; the abnormal probability of the instruction jump sequences is detected through a first detection model, the first detection model is obtained through training of a plurality of normal instruction jump sequences, and the number of instructions in each normal instruction jump sequence is K; and under the condition that the abnormal probability is smaller than a first preset probability, determining that the execution pro
