Kali Linux Bootable USB with Persistence and Wireless on OSX

Download the appropriate Kali Linux .iso

I used a 64 bit .iso image, downloaded via HTTP. I downloaded the amd64 weekly version, as the pool linux headers (needed below for installation of wireless drivers) were ahead of the stable release kernel.

Download the SHA256SUMS and SHA256SUMS.gpg files from the same location.

Don't use VPN services.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

(A Russian translation of this article can be found here, contributed by Timur Demin.)

Why not?

Raspberry Pi VPN Router

This is a quick-and-dirty guide to setting up a Raspberry Pi as a "router on a stick" to PrivateInternetAccess VPN.

How to install debian to a USB drive for use on a MacBook Air

This guide shows how to install debian so that it can be booted and run from a USB drive on a MacBook Air. I use this to store a copy of my PGP master keypair. Networking is deliberately not configured and all operations requiring the master keypair (such as signing other people's keys) are done only on this system. See the debian wiki for information on how to separate your key. Note that this is slightly different to using a live CD. It is not possible to tailor the base configuration of a live CD to one's own requirements, and they frequently automatically connect to the nearest local network. Nevertheless, if you wish to use a live CD instead, I recommend Tails. Arturo Filastò has written a similar guide for Tails.

The method I use requires [VirtualBox][4], which should also contain a working debian installation itself. An alternative method would be to use [debootstrap][5] b
