The Tails Project released the live OS Tails 5.1.1, a live operating system that runs from any computer without leaving traces on the machine or on the internet.
This particular operating Tails was used by her former employee NSA Edward Snowden to stay hidden on the internet.
To use Tails, stop your computer, and start the anonymous operating system from a USB stick instead of Windows, macOS, or Linux. This is how you turn your computer into a very secure machine. You will be safe even if you use someone else's computer.
This version contains important security updates, so it would be good to inform immediately.
