A mouse jiggler is a simple device which does exactly what it says on the tin: moves your mouse a little. This is not by moving your mouse physically, but by emulating a second mouse and sending the commands with the pointer movement. If the mouse is for something like pentesting, those movements are small — only one or two pixels. This is sufficient to make a computer think that it is used, but the user probably will not notice it when it is still on their computer. If you use mouse jiggler to just keep your computer watch, that is less important, as you might want to do if you take an online course requiring a full lecture.In this tutorial, the mouse jiggler is based on a Digispark based on the ATtiny85 Microchip and is an affordable board. It is very small, connects directly to a USB port, making it perfect for discreet pentesting. No other hardware is needed, since all other functions are covered by the Arduino code supplied. This works through the AVRUSB code based DigiMouse library. This library enables you to turn your Digispark into a standard USB HID mouse that appears when it's connected to a computer, as any other mouse. The code causes the mouse pointer to move over and over in a small pixel square to avoid the computer falling asleep. If you want to hack white hats, or just keep your PC active for remote work, it's easy and affordable.
