Tor is a network designed to provide anonymity online by routing web traffic through a network of random servers and protecting it with three layers of encryption. While Tor does not attempt to protect against an attacker monitoring traffic at the boundaries of the network, it does provide protection against traffic analysis. Tor is legal in most countries, but it has been used for illegal activities and is sometimes misunderstood by law enforcement, leading to suspicions and investigations of Tor-using sites. While Tor can protect against traffic analysis, it is not designed to completely erase tracking and does not protect all traffic. Users must take precautions to maintain anonymity, and there is a risk of surveillance or malware injection via malicious exit nodes.

Tor is not designed to completely erase tracking, but to reduce the likelihood of sites tracing actions and data back to the user
Tor is a network designed to provide anonymity to its users by routing web traffic through a network of randomized servers and protecting it with three layers of encryption. This hides a user's IP address from the websites they visit and prevents their ISP (Internet Service Provider) from monitoring their activity. However, it is important to note that while Tor provides anonymity, it does not guarantee complete privacy.
Tor is not infallible, and there have been instances of law enforcement agencies attempting to de-anonymize users. In 2013, it was revealed that the NSA had repeatedly tried and failed to break Tor's core security, but had succeeded in attacking the computers of individual Tor users. Additionally, law enforcement agencies have attributed illegal traffic on the Tor network to Tor exit relays, leading to the mistaken suspicion and arrest of Tor relay operators.
To reduce the risk of being tracked by law enforcement, Tor users are advised to follow certain guidelines, such as using the HTTPS versions of websites, avoiding torrenting, disabling browser plugins, and not opening documents downloaded through Tor while online. Despite these precautions, Tor cannot protect against attackers performing simultaneous monitoring of traffic at the boundaries of the network.
Furthermore, while Tor may make it more difficult for law enforcement to track online activity, it does not provide legal immunity for illegal activities. Law enforcement can still subpoena and obtain information from Tor's developers, and users may face legal consequences for certain actions, even if their identity is not directly linked to those actions.
In conclusion, Tor is a valuable tool for those seeking to protect their anonymity online, but it is not a perfect solution. It reduces the likelihood of sites tracing actions and data back to the user but does not completely erase tracking. Users should be aware of its limitations and take appropriate precautions to protect their privacy and security when using the Tor network.

Tor is not safe against large organisations with time and money, such as the NSA
While Tor does provide a degree of anonymity, it is not entirely secure against large organizations with extensive resources, such as the NSA. Tor is designed to protect against attackers with a single vantage point on the connection, such as an internet service provider. However, it cannot defend against an attacker monitoring traffic at the boundaries of the Tor network.
The NSA, with its vast resources and capabilities, can exploit vulnerabilities in software used in conjunction with Tor, such as web browsers. In the past, the NSA has attempted to crack Tor and has had some success in attacking the computers of individual Tor users. While they may not be able to de-anonymize all Tor users, they can target a small fraction with manual analysis. Additionally, the NSA's surveillance capabilities and access to advanced technology give them an advantage in monitoring online activity.
Tor also faces criticism for its funding sources, which include the U.S. federal government. This raises concerns about potential collaboration with intelligence agencies and the intentional introduction of weaknesses into the system. While Tor's executive director, Andrew Lewman, denied collaboration with the NSA, critics argue that Tor is not as secure as it claims.
Furthermore, law enforcement agencies have successfully intervened with Tor-using sites, such as Freedom Hosting and Silk Road. They employ tactics like running poisoned nodes and exploiting user errors to de-anonymize Tor users. Additionally, agencies can perform forensic analysis of computers, use spyware, and take over websites to determine user identities.
In conclusion, while Tor offers some protection, it is not impenetrable against large organizations like the NSA. The NSA's resources, surveillance capabilities, and potential access to vulnerabilities make it challenging for individuals to maintain complete anonymity, even when using Tor.

Tor is legal to use in most countries, but is illegal, banned, or blocked in some countries to enforce state censorship
Tor is a privacy-focused tool that enhances online anonymity by enabling individuals to route their internet traffic through a global network of servers to hide their IP addresses. While Tor is entirely legal to use in most countries, its association with the dark web and illicit activities has led to it being perceived as questionable in some jurisdictions.
In countries with stricter surveillance, Tor usage may raise suspicion and is sometimes monitored by governments and ISPs. Some countries restrict or block Tor to enforce state censorship and prevent access to anonymous browsing. While there are no documented cases of large-scale de-anonymization, advanced attackers, including government agencies, may employ sophisticated tools to track Tor users. For example, law enforcement agencies can take over a Tor website and use malicious code to identify users.
The legality of Tor usage varies across the globe. For instance, the running of a Tor exit node is an unsettled area of Canadian law. In contrast, Tor is entirely legal in the United States, where it is supported by free speech and privacy rights. The Tor Project itself is based in the United States and operates openly as a nonprofit organization.
While Tor provides a layer of anonymity, it is not without its limitations. It is important to note that Tor does not guarantee complete anonymity, and users must take additional precautions to protect their privacy. For example, users are advised to use the HTTPS versions of websites, disable browser plugins, and refrain from providing personally identifiable information on web forums.
Overall, while Tor is legal in most countries, its usage may be restricted or monitored in certain jurisdictions. It is essential for users to understand the local laws and potential risks associated with Tor usage to make informed decisions about their online privacy and security.

Tor does not attempt to protect against an attacker performing simultaneous monitoring of traffic at the boundaries of the Tor network
Tor is a network designed to provide high-performance anonymity to its users. It does this by protecting against attackers with a single vantage point on the connection, such as control over one of the three relays, the destination server, or the user's internet service provider.
However, Tor does not attempt to protect against attackers who perform simultaneous monitoring of traffic at the boundaries of the Tor network, i.e., the traffic entering and exiting the network. This means that if an attacker controls multiple relays, they can deanonymize users. For example, in 2014, an attacker combined a hundred fast relays and a security bug to deanonymize several Tor users, leading to multiple arrests in the US.
Additionally, Tor does not encrypt the traffic between an exit relay and the destination server. If an application does not add an extra layer of end-to-end encryption, the exit relay can capture and modify traffic. Attacks from malicious exit relays have recorded usernames and passwords and modified Bitcoin addresses to redirect transactions.
While Tor does provide protection against traffic analysis, it cannot prevent traffic confirmation via end-to-end correlation. There are no documented cases of this limitation being exploited at scale. As of the 2013 Snowden leaks, law enforcement agencies like the NSA were unable to perform dragnet surveillance on Tor itself. Instead, they targeted other software used alongside Tor, such as vulnerabilities in web browsers.
To enhance security, Tor users should follow recommended practices, including using HTTPS websites, avoiding torrenting, disabling browser plugins, and not opening downloaded documents while online.

Tor does not collaborate with the NSA to reveal the identities of users
Tor is a free software that enables anonymous communication. It is designed to conceal its users' identities and their online activity from surveillance and traffic analysis by separating identification and routing. While Tor does provide protection against traffic analysis, it cannot prevent traffic confirmation via end-to-end correlation.
Tor is not meant to completely solve the issue of anonymity on the web. It is not designed to completely erase tracking but instead to reduce the likelihood for sites to trace actions and data back to the user. Tor is also used for illegal activities, including privacy protection or censorship circumvention, as well as the distribution of child abuse content, drug sales, or malware.
Tor has been used by criminal enterprises, hacktivism groups, and law enforcement agencies at cross purposes, sometimes simultaneously. Agencies within the U.S. government variously fund Tor and seek to subvert it. In 2012, 80% of The Tor Project's $2 million annual budget came from the United States government, with the aim "to aid democracy advocates in authoritarian states".
Despite Tor's acceptance of funds from the U.S. federal government, Tor's executive director, Andrew Lewman, has stated that the Tor service does not collaborate with the NSA to reveal the identities of its users. In 2013, The Guardian reported that the NSA had repeatedly tried and failed to break Tor's core security, although it had succeeded in attacking the computers of individual Tor users. The NSA attacks target Tor users by exploiting vulnerabilities in their Firefox browsers, not the Tor application directly.
While the NSA has developed tools to identify Tor users by monitoring internet traffic, it has not been able to de-anonymize all Tor users. As of 2016, the FBI was unable to locate, de-anonymize, and identify a Tor user who hacked into the email account of a staffer on Hillary Clinton's email server.

Frequently asked questions
Yes and no. While Tor is designed to provide anonymity, it does not attempt to protect against an attacker performing simultaneous monitoring of traffic at the boundaries of the Tor network. Law enforcement agencies can perform forensic analysis of your computer to determine where you went on Tor, and they can also put spyware on your computer to monitor your activity. However, when you connect to Tor, law enforcement cannot determine what websites you're visiting unless they own those websites and are running exploits.
Tor is legal to use in most countries around the world. However, there are some places where it is illegal, banned, or blocked by authorities to enforce state censorship. These countries include Belarus, Turkey, Russia, Iran, and Saudi Arabia.
Tor is designed to keep you anonymous online, but it does not completely solve the issue of anonymity on the web. It is not designed to completely erase tracking but instead to reduce the likelihood of sites tracing actions and data back to the user.
Yes, there is some evidence that Tor users can be de-anonymized by US law enforcement agencies and academic researchers. Tor can be complicated to use and set up, which means it is easy to reveal your true identity through data leaks or behaviour that might reveal personal information.
No. Tor's developers are available to answer technical questions, but they are not lawyers and cannot give legal advice.
