Сайты, которые не блокируют Tor, могут подтолкнуть вас к просмотру тонны капч. Это не конец света, но это раздражает. Tor Browser направляет весь ваш веб-трафик через сеть Tor, анонимизируя его. Как показывают изображения ниже, Tor состоит из трехслойного прокси-сервера, подобного слоям лука отсюда и логотип Tor.
Tor Browser произвольно подключается к одному из публично перечисленных узлов входа, перенаправляет этот трафик через случайно выбранный средний ретранслятор и, наконец, направляет ваш трафик через третий и последний выходной узел. В результате не удивляйтесь, если Google или другой сервис встретит вас на иностранном языке. Эти сервисы просматривают ваш IP-адрес и угадывают вашу страну и язык, но при использовании Tor вы часто окажетесь в физическом положении на полпути по всему миру.
Если вы живете в стране, которая блокирует Tor, или вам нужен доступ к веб-сервису, который блокирует Tor, вы также можете настроить Tor Browser на использование мостов. В отличие от узлов входа и выхода Tor, IP-адреса мостов не публикуются в открытом доступе, поэтому веб-службам и правительствам сложно занести эти IP-адреса в черный список.
Сеть Tor маршрутизирует TCP-трафик всех видов, но оптимизирована для просмотра веб-страниц. Tor не поддерживает UDP, поэтому не пытайтесь торрентировать ISO-образы свободных программ, поскольку они не будут работать. В России браузер Tor запрещен. Однако в некоторых странах Tor либо запрещен, либо заблокирован национальными властями. Китай запретил службу анонимности и блокирует движение Tor через Большой межсетевой экран.
Легко понять, почему репрессивный режим ненавидит Tor. Служба облегчает журналистам репортажи о коррупции и помогает диссидентам организовываться против политических репрессий. Свобода общаться, публиковать и читать анонимно является предпосылкой свободы выражения мнений в Интернете и, следовательно, предпосылкой демократии сегодня. Использование и поддержка Tor помогает поддерживать свободу слова во всем мире.
Технически искушенным пользователям рекомендуется жертвовать пропускную способность сети Tor путем запуска ретранслятора. Tor Browser предлагает лучший анонимный веб-браузер, доступный сегодня, но эта анонимность не идеальна.

In September , Dan Egerstad, a Swedish security consultant, revealed he had intercepted usernames and passwords for e-mail accounts by operating and monitoring Tor exit nodes. While this may not inherently breach the anonymity of the source, traffic intercepted in this way by self-selected third parties can expose information about the source in either or both of payload and protocol data.
Who would pay for this and be anonymous? In October , a research team from ESIEA claimed to have discovered a way to compromise the Tor network by decrypting communication passing over it. Then, using these known keys and seeds, they claim the ability to decrypt two encryption layers out of three. They claim to break the third key by a statistical attack. In order to redirect Tor traffic to the nodes they controlled, they used a denial-of-service attack.
There are two methods of traffic-analysis attack, passive and active. In the passive traffic-analysis method, the attacker extracts features from the traffic of a specific flow on one side of the network and looks for those features on the other side of the network.
In the active traffic-analysis method, the attacker alters the timings of the packets of a flow according to a specific pattern and looks for that pattern on the other side of the network; therefore, the attacker can link the flows in one side to the other side of the network and break the anonymity of it. Steven Murdoch and George Danezis from University of Cambridge presented an article at the IEEE Symposium on security and privacy on traffic-analysis techniques that allow adversaries with only a partial view of the network to infer which nodes are being used to relay the anonymous streams.
Murdoch and Danezis have also shown that otherwise unrelated streams can be linked back to the same initiator. This attack, however, fails to reveal the identity of the original user. Operators of Internet sites have the ability to prevent traffic from Tor exit nodes or to offer reduced functionality for Tor users. For example, it is not generally possible to edit Wikipedia when using Tor or when using an IP address also used by a Tor exit node.
The BBC blocks the IP addresses of all known Tor guards and exit nodes from its iPlayer service, although relays and bridges are not blocked. One method of attack depends on control of an exit node or hijacking tracker responses, while a secondary attack method is based in part on the statistical exploitation of distributed hash table tracking.
The attack targeted six exit nodes, lasted for twenty-three days, and revealed a total of 10, IP addresses of active Tor users. This study is significant because it is the first documented attack designed to target P2P file-sharing applications on Tor. The study was conducted by monitoring six exit nodes for a period of twenty-three days. Researches used three attack vectors : . With this technique, researchers were able to identify other streams initiated by users, whose IP addresses were revealed.
Jansen et al. The attack works using a colluding client and server, and filling the queues of the exit node until the node runs out of memory, and hence can serve no other genuine clients. By attacking a significant proportion of the exit nodes this way, an attacker can degrade the network and increase the chance of targets using nodes controlled by the attacker.
On 30 July the Tor Project issued the security advisory "relay early traffic confirmation attack" in which the project discovered a group of relays that tried to deanonymize onion service users and operators. The attacking relays were stable enough to achieve being designated as "suitable as hidden service directory" and "suitable as entry guard"; therefore, both the onion service users and the onion services might have used those relays as guards and hidden service directory nodes.
The attacking nodes joined the network early in the year on 30 January and the project removed them on 4 July. The project mentioned the following mitigations besides removing the attacking relays from the network:. In November there was speculation in the aftermath of Operation Onymous , resulting in 17 arrests internationally, that a Tor weakness had been exploited. A representative of Europol was secretive about the method used, saying: " This is something we want to keep for ourselves.
Andrew Lewman—a Tor Project representative—downplayed this possibility, suggesting that execution of more traditional police work was more likely. In November court documents on the matter  generated serious concerns about security research ethics  and the right of not being unreasonably searched were guaranteed by the US Fourth Amendment. In , the administrators of Agora , a darknet market , announced they were taking the site offline in response to a recently discovered security vulnerability in Tor.
They did not say what the vulnerability was, but Wired speculated it was the "Circuit Fingerprinting Attack" presented at the Usenix security conference. A study showed "anonymization solutions protect only partially against target selection that may lead to efficient surveillance" as they typically "do not hide the volume information necessary to do target selection". The Tor Browser  is the flagship product of the Tor Project.
Murdoch  and announced in January The Tor Browser automatically starts Tor background processes and routes traffic through the Tor network. Upon termination of a session the browser deletes privacy-sensitive data such as HTTP cookies and the browsing history.
The warrant alleges that Marques is "the largest facilitator of child porn on the planet". In April , the Tor Project shut down the Tor Messenger project because the developers of Instantbird discontinued support for their own software. OnionShare allows to share files using Tor. The Guardian Project is actively developing a free and open-source suite of applications and firmware for the Android operating system to improve the security of mobile communications.
Several security-focused operating systems make extensive use of Tor. Tor has been praised for providing privacy and anonymity to vulnerable Internet users such as political activists fearing surveillance and arrest, ordinary web users seeking to circumvent censorship, and people who have been threatened with violence or abuse by stalkers.
National Security Agency NSA has called Tor "the king of high-secure, low-latency Internet anonymity",  and BusinessWeek magazine has described it as "perhaps the most effective means of defeating the online surveillance efforts of intelligence agencies around the world".
Advocates for Tor say it supports freedom of expression , including in countries where the Internet is censored, by protecting the privacy and anonymity of users. The mathematical underpinnings of Tor lead it to be characterized as acting "like a piece of infrastructure , and governments naturally fall into paying for infrastructure they want to use".
The project was originally developed on behalf of the U. State Department , the Broadcasting Board of Governors , and the National Science Foundation as major contributors,  aiming "to aid democracy advocates in authoritarian states".
Naval Research Laboratory , and the Government of Sweden. Tor executive director Andrew Lewman said that even though it accepts funds from the U. Critics say that Tor is not as secure as it claims,  pointing to U. The citation read, "Using free software, Tor has enabled roughly 36 million people around the world to experience freedom of access and expression on the Internet while keeping them in control of their privacy and anonymity. Its network has proved pivotal in dissident movements in both Iran and more recently Egypt.
In , Foreign Policy magazine named Dingledine, Mathewson, and Syverson among its Top Global Thinkers "for making the web safe for whistleblowers". In , Jacob Appelbaum described Tor as a "part of an ecosystem of software that helps people regain and reclaim their autonomy. It helps to enable people to have agency of all kinds; it helps others to help each other and it helps you to help yourself.
It runs, it is open and it is supported by a large community spread across all walks of life. In September , in response to reports that Comcast had been discouraging customers from using the Tor Browser, Comcast issued a public statement that "We have no policy against Tor, or any other browser or software. In October , The Tor Project hired the public relations firm Thomson Communications to improve its public image particularly regarding the terms "Dark Net" and "hidden services," which are widely viewed as being problematic and to educate journalists about the technical aspects of Tor.
In July , the Tor Project announced an alliance with the Library Freedom Project to establish exit nodes in public libraries. Although the DHS had alerted New Hampshire authorities to the fact that Tor is sometimes used by criminals, the Lebanon Deputy Police Chief and the Deputy City Manager averred that no pressure to strong-arm the library was applied, and the service was re-established on 15 September Surveillance has a very well-documented chilling effect on intellectual freedom.
It is the job of librarians to remove barriers to information. In August , an IBM security research group, called "X-Force", put out a quarterly report that advised companies to block Tor on security grounds, citing a "steady increase" in attacks from Tor exit nodes as well as botnet traffic.
In September , Luke Millanta created OnionView, a web service that plots the location of active Tor relay nodes onto an interactive map of the world. In March , New Hampshire state representative Keith Ammon introduced a bill  allowing public libraries to run privacy software.
The bill specifically referenced Tor. The text was crafted with extensive input from Alison Macrina , the director of the Library Freedom Project. Lovecruft has legal representation from the Electronic Frontier Foundation. On 2 December , The New Yorker reported on burgeoning digital privacy and security workshops in the San Francisco Bay Area , particularly at the hackerspace Noisebridge , in the wake of the United States presidential election ; downloading the Tor browser was mentioned.
Tor and Bitcoin was fundamental to the operation of the darkweb marketplace AlphaBay , which was taken down in an international law enforcement operation in July The Russian-speaking underground offering a crime-as-a-service model is regarded as being particularly robust.
In June , Venezuela blocked access to the Tor network. The block affected both direct connections to the network and connections being made via bridge relays. On 20 June , Bavarian police raided the homes of the board members of the non-profit Zwiebelfreunde, a member of torservers. The hardware and documentation seized had been kept under seal, and purportedly were neither analyzed nor evaluated by the Bavarian police. Since October , Chinese online communities within Tor have begun to dwindle due to increased efforts to stop them by the Chinese government.
In November , Edward Snowden called for a full, unabridged simplified Chinese translation of his autobiography, Permanent Record , as the Chinese publisher had violated their agreement by expurgating all mentions of Tor and other matters deemed politically sensitive by the Communist Party of China.
Tor responded to earlier vulnerabilities listed above by patching them and improving security. In one way or another, human user errors can lead to detection. The Tor Project website provides the best practices instructions on how to properly use the Tor browser. When improperly used, Tor is not secure. For example, Tor warns its users that not all traffic is protected; only the traffic routed through the Tor browser is protected.
Users are also warned to use https versions of websites, not to torrent with Tor, not to enable browser plugins, not to open documents downloaded through Tor while online, and to use safe bridges. The best tactic of law enforcement agencies to de-anonymize users appears to remain with Tor-relay adversaries running poisoned nodes, as well as counting on the users themselves using the Tor browser improperly. When properly used, odds of being de-anonymized through Tor are said to be extremely low.
At present the Tor network offers, out of a total of around 7, relays, around 2, guard entry nodes and around 1, exit nodes. From Wikipedia, the free encyclopedia. This is the latest accepted revision , reviewed on 19 January This article is about the software and anonymity network.
