Debian and its derivatives
are [the most popular Linux distributions on web
servers](https://w3techs.com/technologies/details/os-linux) across the
Internet.

The Debian project is coordinated over the Internet by a team of
volunteers whose work is entirely public. All this makes Debian one of the
Free Software projects under the most scrutiny by security researchers.

Tails is made by the Tor Project, the same organization that makes the Tor
software and *Tor Browser*.

[Tor](https://torproject.org/) is the best anonymity network available. Tor Tor
has partnered with leading research institutions and has been subjected to
intensive academic research. Tor has received awards from institutions
such as the [EFF](https://www.eff.org/awards/pioneer/2012) and the [Free
Software
Foundation](https://www.fsf.org/news/2010-free-software-awards-announced).
Even the NSA qualified Tor as "[the King of high secure, low latency Internet
Anonymity](https://www.theguardian.com/world/interactive/2013/oct/04/tor-high-secure-internet-anonymity)."

Pretend to be the destination server, a technique known as <i>machine-in-the-middle</i> attack (MitM). That is why you should pay even more attention to the security warnings in <i>Tor Browser</i>. If you get such a warning, use the [[New Identity|doc/anonymous_internet/Tor_Browser#new-identity]] feature of <i>Tor Browser</i> to change exit node.

Tor exit nodes have been used in the past to collect sensitive information from unencrypted connections. Malicious exit nodes are regularly identified and removed from the Tor network. For an example, see <a href="https://arstechnica.com/information-technology/2007/09/security-expert-used-tor-to-collect-government-e-mail-passwords/">Ars Technica: Security expert used Tor to collect government e-mail passwords</a>.
