The invention discloses a risk behavior detection method, a device, equipment and a computer readable storage medium, and the method comprises the steps: collecting historical behavior data of a user,carrying out the formatting of the historical behavior data, and extracting the feature information of the historical behavior data; selecting the feature information of the normal behavior historical data and the feature information of the dangerous behavior historical data from the feature information of the historical behavior data to generate a user behavior sample; training a classificationalgorithm by using the user behavior sample to obtain a target behavior classification algorithm; formatting the current business behavior data, and extracting feature information of the current business behavior data; inputting the feature information of the current business behavior data into a target behavior classification algorithm, and outputting a risk score of the current business behavior; and if the risk score is greater than or equal to the threshold, determining that the current business behavior is a high-risk behavior. According to the method, the device, the equipment and the computer readable storage medium provided by the invention, the efficiency, the accuracy and the real-time performance of risk behavior detection are improved.
