Websites leave tracking cookies, following you from page to page and session to session, alongside the usual traces left by your IP address. Persistent logins from Google and Facebook tie each site visit to your offline identity. If anyone really wants to go after you, they can also make a direct attack, targeting malware to track your movements in the background. With the right tools, a computer is an open book.
Not this computer, though. It's running Tails, an open-source operating system designed to leave as little trace as possible, launching version 1.0 today after more than five years of open development. It's an amnesiac system, which means it's completely fresh every time you boot up. There are no save files, no new programs, and most importantly, it becomes a blank slate the moment you shut down. It's the digital equivalent of buying a new computer for a single session and tossing it into the river once you're done.
That trick has earned Tails a lot of attention. It’s already standard software at Glenn Greenwald’s First Look Media, where he’s called it “vital to my ability to work securely on the NSA story.” Tor researcher Jacob Appelbaum praised the project onstage at this year's Chaos Communications Congress, and in March Tails received a $50,000 grant to keep the project going. Nearly 8,500 computers booted up with Tails on a given day in March, 500 more than the month before. Those are surprisingly high numbers for a project that’s this hard to use, and does this little. But if you need a secure line, Tails is the best way to get it. In the era of the NSA, that’s a rare thing.
Making it work
Tails works by booting your computer off of an external disk — usually a USB drive, an SD card or a CD — but getting Tails onto the right storage drive is harder than it sounds. Ideally, you’d keep it on a CD: once it’s burned into the plastic, the code can't be changed, making it completely immune to malware. But with new versions being released every few months (and plenty of laptops going without CD drives), a USB stick can be more convenient. We used Rufus to make a bootable version on a USB drive and SD card, but even then, certain flash drives simply won’t work with Tails. There are ways to add encrypted storage or persistent programs too, but each extra feature is also a new chance for security problems.
Getting Tails onto a computer isn’t straightforward either. There’s a long list of computers that can’t run the OS, and it includes most of the computers made by Apple. We spent the better part of a day trying to launch it on a Toshiba Kirabook, only to have Windows 8 punch through every time. It ends up working best on machines that are Linux-friendly, without anything like a high-powered video card to trip things up. There are a few different stable setups, but lots of ways to accidentally break your own security.
