I was challenged in university to Hack a mouse in the following manner:
What is happening: computer1 has an optical mouse connected to it, and this optical mouse has been hacked in one way or another so computer2 can send commands to the Arduino which in turn sends commands to the optical mouse that control the cursors movements in computer 1.
Basically all the drivers and all that stuff that the optical mouse of computer1 had is not being changed. I have to hack into the mouse at some point to change the information that is being given. It could be at the sensors (sending predesigned images to them to provoke specific movements) or it could be somewhere after the information from the sensor has already been analysed. Basically computer1 has no idea the Arduino is interfering in any process, very under the radar.
I am not sure however how I would go about doing this... hacking the sensor would require me to design images that would be sent to the mouse.... not sure how the hacking there would work. If I were to hack the end result of the images being analysed, I would have to find out at what point is the mouse sending this information (and over which peace of circuitry) and find a way of intercepting and replacing this information.
Which of the 2 options do you guys believe is more realistic and why?
