802.11pwned

802.11pwned, or 802.11p, is not a new technology based off of 802.11 wireless networking. It's a dedication to hardening security of the protocol by auditing, exploiting and publishing findings to force vendors to update technology rather than the popular model of "security by obscurity", where vulnerabilities are patched with a "routine" update.

This blog is dedicated to doing this. With many off the shelf hardware and freely available software, you are able to audit your own wireless network to harden it from attacks from the inside and outside.

Wireless networking is not the most secure technology in the world. Wireless packets are constantly being broadcasted in the air and are susceptible to being captured by malicious or curious people. If you want security - unplug your wireless router and go wired Ethernet.

Mushroom Cantenna



This is a "mushroom cantenna", made with very simple household materials. The basic construction is a plastic or foam mushroom antenna, tin foil (dull side out), some bread bag ties, and some creativity. My wireless card, a TP-Link TL-WN321G ($9 from Amazon), works well in my cantenna. It has a loop on the top so I can pull the card "tight" in the cantenna so it doesn't flop around and is not solely relying on the USB cable to keep it upright.

I poked a hole in the plastic container, ran a breadbag tie through the top, and pulled it tight. I just lined the container with foil, with no hot glue or tape, and let the wireless card hold it straight.



This is a side view of my creation. As you can see at the very top, I poked a hole through the rear of the top of the container to run a bread bag tie, so it can hook onto the curtain hook in my window. Midway through the container, I poked two sets of holes so I can run ties through them and secure them to a pole or whatever I need to secure them to to get a signal boost. I have a tripod from a fold up music stand, which I'm going to convert into a wireless tripod to hold up my cantenna so the signal is not being blocked on my porch.

I can test the signal with various utilities and see if I'm getting the actual performance boost I want, or if the signal isn't working. I will post screen shots of my research on this blog for others to see what types of cantennas work, and what cantennas don't work.

Creativity is everything :-)
