Yes the students did have a contract but the school district left out the part of trying to breach the firewall or other systems to try and make it easer on me. having the students create the breach then we patch it out by watching there screen on how to do it , or asking them. but the student that uses the ducky is able to walk up to and Chromebook and run the script and all we see is a hid keyboard was attached and our systems don't log key strokes but it does log usage over the network.
