This time on the show, we continue hacking the airwaves with RFcat, a usb radio dongle and a little python lovin'. Then I'm setting up a bit of counter surveillance rig the easy way with a live Onion Router distro. Plus, portable VPN clients for unprivileged users - what are your open source options? All that and more, this time on Hak5!

Tails and the Onion Router

Tails is a Linux Distro that boasts mainly about their privacy and anonymity for users. Connections go straight through Tor. The Tor Project is free software and an open network that helps you defend against network surveillance, letting you keep your information private. Tor bounces traffic throughout the world, so someone can't learn who you are or what sites you visit, and the sites can't figure out where you're from. Tails has to be booted from a flashdrive or a cd- installing a distro on a computer can leave traces of your actions on that computer. Tails also uses encryption for your files, data, and even instant messaging. When you boot into Tails, it uses RAM memory, not hard drive space, so any traces are wiped clean upon shut down. You can still save data to another harddrive or USB while using Tails, so if you're working on an important secure file, you won't lose all of your work.

Tails comes with a series of cryptographic tools for encryption. HTTPS Everywhere for private browsing, LUKS for USB encryption, OpenPGP for email, OTR for encrypting instant messages, and Nautilus Wipe to wipe your files from the computer completely.

Of course, there are always security loopholes and problems, and the Tails creators give a great layout of what to expect when using this distro on their page. You do have to give some trust to Tails if you want to use it to it's full advantage.

Feedback

Clifford asks: Hey guys, I am always on the go and need access to my home network for a growing number of reasons. Do you know of a free portable vpn client that can fit on a flash drive.

• OpenVPN Portable: ovpnp.sf.net - open source, windows only, openvpn support.
• KiTTY: http://www.9bis.net/kitty/ - open source, windows only, fork of PuTTY for non-admin, does SSH tunneling.
• Few other non-open source apps but can't recommend 'em.
• Does anyone else know of something?
