Where would be a good place to start? OpenBSD? http://www.skeptech.org/blog/2013/01/13/unscrewed-a-story-about-openbsd/ http://www.skeptech.org/blog/2013/01/13/

Where would be a good place to start? OpenBSD? http://www.skeptech.org/blog/2013/01/13/unscrewed-a-story-about-openbsd/ http://www.skeptech.org/blog/2013/01/13/unscrewed-a-story-ab... Another platform? It's tricky. You could for example pick seL4, but then you have no router. That could be interpreted as an amazing opportunity to make a new stack, or a feat significantly less interesting and more strenuous than climbing Mt. Everest. Then on the hardware side, do you pick x86 (complete with firmware that lets you use fallthru to ring -2! \o/), ARM, MIPS, or what? This is a question I've no idea how to answer. Also, heh, I'm reminded of this: 1. Search Shodan for JAWS/1.0 2. Take one of the results, go to the IP[:port], append "/shell?" and a command, eg "/shell?ls" 3. Try running "whoami" 4. Go back and look at the number of results 5. Visit the IPs normally, and learn that these are DVRs, for security cameras; alternate between dying inside and reattaching your jaw.
