All traces of Tor users on the Internet are thus hidden. For each request, a route is randomly selected through one of the three nodes, and each next node encrypts the previous one. The principle of operation of Tor is that the user's request to access the site is first encrypted to the input node with its own IP address. This opportunity has made Tor a popular tool in the hands of lawbreakers who trade in the sale of drugs and weapons, the distribution of pornography and other illegal activities. In addition, Tor opens access to the darknet - a hidden segment of the Internet in which underground information resources are concentrated. Tor gives the user the ability to save incognito on the Internet and protects his traffic from analysis, and also allows you to bypass some types of blocking of Internet resources. Tor is a system of proxy servers that support 'onion routing' - a technology for anonymous exchange of information through a computer network. In 2002, the development was declassified, and the source codes were transferred to independent developers who created client software and published the source code under a free license so that everyone could check it for vulnerabilities. Initially, the Tor system was developed in the laboratory of the US Navy by federal order. The project site ( ) defines Tor (The Onion Router) as free software and an open network of servers to protect against network surveillance, known as traffic analysis that threatens personal freedom and privacy, privacy of business contacts and communications, and state security. 2008: Tor's connection to the US government.Interior Ministry investigates the possibility of hacking Tor.FBI paid $1 million to hack anonymous Tor network.More than 100 key nodes of the Tor network monitor users.IP addresses of Tor servers are blocked in Belarus.Tor taught how to install on a PC in countries where it is tightly locked.The creator of Tor explained how Roskomnadzor will be able to block Tor.The attacker earned $760 thousand on fake domains in the dark net.Russia came out on top in the number of users of the Tor browser.Researchers: Unencrypted traffic on Tor reveals sensitive data.2020: Unknowns take possession of a quarter of Tor nodes for attacks on users.Removal of blocking from the service in Russia.Tor 0.4.7.7 with Congregation Control system.The court canceled the blocking of the Tor site in Russia.Roskomnadzor unlocked the Tor website in Russia.
