BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Figure 1 This is a flowchart of the method in Example 1 of the present invention;

[0027] Figure 2 This is a schematic diagram of the structure of the device in Example 2 of the present invention. DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of this application have the following general ideas:

[0029] The entire system consists of a computer, a set of Windows test software (Mouse Test Software), a small MCU development board, multiple PWM motors, several levers, cams, and gears.

[0030] Let the Mouse Test Software use the motor rotation to automatically control the physical actions of moving the mouse left and right or clicking buttons;

[0031] Click action: One end of the lever is mounted on the motor and rotates with the motor, while the other end is mounted on a cam. It uses the principle of a cam mechanism. When the cam rotates, it drives the follower to move up and down to achieve a click.

[0032] Scrolling action: One end of the lever is mounted on the motor and rotates with the motor, while the other end is mounted on a cam. When the cam rotates, it drives the mouse scroll wheel to rotate.

[0033] Movement: A sliding lever is connected to a suction cup, which holds the mouse. Clockwise or counterclockwise rotation of the motor will drive the sliding lever to move the mouse left or right.

[0034] USB Hub Module Features

[0035] 1. Contains normal USB Hub bus functions.

[0036] 2. Mouse Test Software can control the USB Hub to power on and off a single USB port.

[0037] Functions of the Mouse Test Software module

[0038] 1. The software has a built-in set of use cases that include all system events that can be generated by standard keystrokes. System events are mapped to a configuration parameter. After the mouse button is set to this parameter, pressing the button will generate the system event. (Normal parameter settings)

[0039] 2. Generate a random string of data parameters based on the parameter rules and length of the mouse setting interface and send it to the mouse. (Random parameter setting, abnormal parameter setting, the mouse must be able to maintain the original button function)

[0040] 3. Send commands to the MCU to control the motor device to rotate clockwise or counterclockwise a corresponding number of times to make the mouse perform physical actions such as sliding and clicking. The coordinate position of the mouse cursor and the system key events generated when the key is pressed are obtained through the Windows system to determine whether the mouse is normal.

[0041] (Physically moving the mouse to the left or right will cause the coordinates of the mouse cursor in the Windows system to change accordingly)

[0042] 4. Record the string of setting parameters that causes the mouse to behave abnormally.

[0043] 5. Control the USB Hub to power on the mouse again to reset and restart the mouse after an abnormality.

[0044] 6. Repeat the test in steps 2-5.

[0045] Functions of the MCU module

[0046] 1. Receive the move or click event commands sent by the Mouse Test Software.

[0047] 2. Control PWM output to control the motor to make corresponding physical movements to generate events such as mouse clicks.

[0048] Example 1

[0049] like Figure 1 As shown, this embodiment provides a method for automatically detecting mouse firmware vulnerabilities, including: a PC, an MCU, and four motors, wherein the PC is connected to the MCU; the MCU is respectively connected to the four motors, one motor controls clicking the left button of the mouse, one motor controls clicking the right button of the mouse, one motor controls moving the mouse left and right, and one motor controls scrolling the mouse wheel;

[0050] Step 1. Set up a set of use cases that include all system events generated by standard buttons. Map the system events to a configuration parameter. After the mouse button is set to the parameter, the MCU controls the motor to perform the corresponding actuation, and the Windows responds to the corresponding system event. Test whether the mouse is operating normally. If it is normal, proceed to step 2. If not, report an exception. During the test, only a few functions need to be randomly tested to ensure that the basic functions of the mouse are normal (basic functions include: left button, right button, scroll wheel, and movement).

[0051] Step 2: Based on the parameter rules and length of the mouse setting interface, a string of parameters is randomly generated and sent to the mouse;

[0052] Step 3: Send a command corresponding to the string of parameters to the MCU to control the motor, so that the mouse performs a corresponding physical action, and obtain a system event response after the mouse action through the Windows system;

[0053] Step 4: If an exception occurs, record the randomly generated string of parameters; if no exception occurs, do not record;

[0054] Step 5: Power on the mouse again to reset the mouse after the abnormality occurs.

[0055] Step 6: Repeat steps 2 to 5 until the test is completed and store all recorded parameters.

[0056] In another preferred solution of this embodiment, a USB Hub is further included; the PC is electrically connected to the mouse and the MCU respectively through the USB Hub.

If normal, it enters the stress test module; if not, it reports an abnormality; during the test, only a few functions need to be randomly tested to ensure that the basic functions of the mouse are normal (basic functions include: left button, right button, pulley and movement). After the mouse movement and click operation, there will be corresponding reactions in the computer, and the mouse is judged by the reaction.

[0061] The stress test module randomly generates a string of parameters and sends it to the mouse according to the parameter rules and length of the mouse setting interface;

[0062] The actuation module sends a command corresponding to the string of parameters to the MCU to control the motor, so that the mouse performs a corresponding physical action, and obtains a system event response after the mouse actuation through the Windows system;
