<p>first stab at it</p> <p><b>New page</b></p><div>A level under development for the [[Skullspace_Hardware_Programming_Challenge]].<br /> <br /> * Platform: [[wikipedia:Raspberry Pi|Raspberry Pi]] or similar -- as long as it can run [http://sourceforge.net/projects/libusb/ libusb]<br /> * IO: control over a light and a USB webcam<br /> * Level master: Mark Jenkins<br /> * Difficulty: medium<br /> <br /> Webcams are [http://boingboing.net/2010/02/17/school-used-student.html creepy. Very, very, creepy].<br /> <br /> The level consists of a black box that has only one interface to the outside world, an ethernet port. Inside, a little computer (perhaps a Raspberry Pi) that's running a web server with a [[wikipedia:Buffer_overflow|buffer overflow]] vulnerability.<br /> <br /> The secret message is on the inside wall. Facing that wall on the inside is a webcam connected to the vulnerable computer. <br /> <br /> Your mission is to prove to your friends how creepy webcams really are by photographing the secret message. But, it's dark inside the box. In order to take a reasonable image you also have to use some general purpose IO to turn on the light bulb.</div>
