Different ways to use TOR

While catching up on SANS’ Internet Storm Center Storm Cast during my drive, I heard this episode. In it Johannes Ullrich was mentioned this article about using DRM Decloaking TOR users. Short version, users running the Tor Browser Bundle click a link, and Microsoft Windows launches the media player not using the TOR network, exposing the user’s real IP address.

This attack could be mitigated by using TAILS or something else that forces all traffic through TOR. Which made me think I should share all the ways I use TOR.

Why I don’t have a lab

An industry mailing list I’m on recently had a conversation that started asking about Master Degrees but had some hiring managers chip in. They said a question they tend to ask is to have the candidate tell about their home lab.

I’ve been asked this question a few times in the past, and I’ve asked people this question in job interviews. I know it’s to find out what kind of passion the candidate has for the job, but I think it’s starting to become a bad question to ask.

Here is why I don’t have a home lab.

Raspberry Pi projects

Back in May and June, I did a project for school with 6 Raspberry Pis to build a WIDs. It went good. I wrote an article, I’m waiting to hear back if it’ll get published.

After the project, I had 6 Raspberry Pis kicking around. I have a project I want to work on, that could lead to another article. I just need to build my skills up to that first.

To get there, I wanted to build an Onion Pi. This will tie in to another project I’m working on. As some of you know I’m a fan of The Onion Router (TOR), especially when I’m doing Intelligence related research. The Onion Pi would be a good thing to have in the bag of tricks.

To get the Onion Pi working, I needed to go through the Adafruit Wifi Access Point. This is the second time I build an AP. This one is just a little different than last time. This time instead of an Edimax wireless card, I went with one of my TP Link TL-WN722Ns. I wanted the external antenna. I was using the 2014-09-09_wheezy_raspbian image.

Hostapd didn’t work right. It kept throwing errors on start about nl80211 not being a known driver. I had to build hostapd from source, which needed to have libssl-dev and libnl-1.1 installed, to get hostpad to build right. Then I needed to copy my built version into the right place.

I also had problems with isc-dhcp-server and tor starting. It looks like wlan0 isn’t starting properly. I’ll have to troubleshoot it more later. Adafruit has a comment about disabling wpa_supplicant. I don’t know if that will fix the problem though. I’ll follow up after.
