Are we still in the 80s? Trust is not inherit and NCSI probes are plain silly, surely there has to be a better way for your icons. The cure works but the breaks in the UX make it better to keep such a disease...
I was bored. I love hacking wifi and there hasn't been anything new to do in quite the while. I figured it'd be cool to come up with an endpoint for this vector concept. BeEF absolutely came to mind but the issue with such a tool is that if the user closes the browser the vector dies and well, hmm. What information can we grab during the short time the browser will be open?
