While I was reading the shallow description of the plugbot (http://theplugbot.com/about) I was wandering if those guys are making the hardware itself. A bit of googleing answer my question – pretty sure they don’t. There is a separate project called Plugcomputer (plugcomputer.org) that gives an answer to most of my questions regarding the device.
The overall idea behind it is pretty old one – walk in, plug remote controllable device inside targeted premises and walk away. Stay with fingers crossed no one will spot the device and remove it and try to command it remotely. I guess everyone can imagine a linux distribution armed with certain security tools and with simplified interface to interact remotely and probably that’s what Red Security team is trying to build, but it still looks neat.
Wish them luck with the project!
