A Tor site is an onion service open only through the Tor network; its URL ends in '.onion' with 56 characters before that suffix[1][2]. To visit:

  • Get Tor Browser only from https://download.torproject.org/[3].

  • Use the exact .onion address; Tor checks it connects to the right location without tampering[2].

  • Germany’s BSI says browsing alone is not illegal[4].

What a Tor Site Actually Is

A Tor site is a service reachable only through the Tor network, identified by a '.onion' address instead of regular domains like '.com' or '.org'[1]. The address consists of 56 randomly generated letters and numbers followed by '.onion', created automatically through cryptography rather than purchased from a registrar[2]. This random-looking string is actually a public key that encodes the service's ed25519 master public key, a version byte, and a checksum in base32 format[5].

Three distinct concepts often get confused:

  • Tor network – the overlay routing system that encrypts and bounces your connection through volunteer relays.

  • Tor Browser – the application you download from the Tor Project to access both the regular web and '.onion' services[3].

  • Tor site – a specific website or service hosted as an onion service, accessible only via the Tor network[1].

You cannot reach a '.onion' address through Chrome, Firefox, or any standard browser; the cryptography involved lets Tor verify it is connecting to the correct location and that no one is tampering with the connection[2]. The Australian Cyber Security Centre defines the dark web as content not indexed by search engines and accessible only through specialty networks such as Tor[6], and Tor sites form one part of that layer.

A '.onion' address does not automatically mean illegal activity. According to the US Cybersecurity and Infrastructure Security Agency, many people use the dark web for entirely legitimate reasons such as political dissidence and private communication, not only for cybercriminal activity[7]. Germany's Federal Office for Information Security states that browsing the dark net alone is not illegal; you become a criminal only when you consume illegal content or purchase illegal goods[4]. The Tor Project itself explains that onion services allow people both to browse and to publish anonymously, including running anonymous websites[1].

What matters is the content and your actions, not the technology. A Tor site is simply a service reachable only through Tor Browser—nothing more, nothing less.

How Tor Sites Differ from Regular Websites

When you visit a regular website, your browser contacts a server on the public internet, often resolving a domain name through DNS and then establishing a direct connection. A Tor site works differently: your traffic stays inside the Tor network from start to finish, never touching the public internet in the same way[1]. The onion service itself runs as a hidden service within Tor, and both you and the site operator remain anonymous to each other unless one party chooses to reveal identifying information.

Routing and Reachability

A typical website can be reached from any browser and is usually indexed by Google, Bing, or other search engines. A '.onion' address is not indexed by any search engine and requires Tor Browser to connect[7]. The Congressional Research Service describes the dark web as the segment of the deep web that has been intentionally hidden, referring to sites users generally cannot access without special software and where publishers are often concealed[8]. Because the '.onion' URL encodes a cryptographic public key, Tor can verify you are connecting to the authentic service and that the connection is not being tampered with[2].

Many Tor sites have no clearnet equivalent—they exist only as onion services. Others are mirrors: the same organization runs both a regular website and a '.onion' version. For example:

  • BBC operates an onion mirror of BBC News.

  • The New York Times provides an onion service for readers in countries with internet censorship.

  • Facebook runs facebookwkhpilnemxj7asaniu7vnjjbiltxjqhye3mhbshg7kx5tfyd.onion to let users access the platform through Tor.

These official mirrors illustrate that onion services are not inherently illicit; they offer an additional layer of privacy and censorship resistance for legitimate users[7].

Why Addresses Look Random

The 56-character string before '.onion' is not a memorable name chosen by a marketing team. It is a base32-encoded representation of the service's ed25519 master public key, a version byte, and a checksum[5]. Operators do not purchase or register these addresses from a domain registrar; the address is generated automatically when the service is created[2]. This cryptographic foundation is what allows Tor to authenticate the service and protect the connection, but it also means you must copy and paste addresses carefully or bookmark them—mistyping even one character will send you to a non-existent or different service.

What You Need Before Opening a Tor Site

You do not need special hardware, a technical background, or any payment to visit a Tor site. Three things are essential: Tor Browser from the official source, an updated operating system, and the exact '.onion' address you intend to visit. Each requirement exists for a reason, and skipping any one of them exposes you to risk.

Download Tor Browser from the Official Source Only

The safest and simplest way to download Tor Browser is from the official Tor Project website at https://download.torproject.org/, where the connection is secured using HTTPS[3]. The current stable release is version 16.0, available for Windows, macOS, and Android[9]. Do not download Tor Browser from third-party sites, app stores, or torrent repositories. Modified versions can contain malware, tracking code, or backdoors that compromise your privacy before you even open your first '.onion' link.

Each file on the Tor download page is accompanied by an OpenPGP signature file with the '.asc' extension that lets you verify the package was generated by the developers and has not been tampered with[10]. If you are new to signature verification, the Tor Project provides step-by-step instructions on its support pages. For most users, downloading directly from https://download.torproject.org/ over HTTPS offers sufficient assurance.

Keep Your Operating System Updated

Tor Browser cannot protect you if your underlying operating system is outdated or compromised. Install all security patches for Windows, macOS, or your Linux distribution before downloading Tor Browser. An unpatched system can leak identifying information or allow malware to monitor your activity, rendering Tor's anonymity protections useless.

Know the Exact Address You Plan to Visit

Unlike the clearnet, where you can type a partial domain into Google and find the site you want, Tor sites are not indexed by search engines[7]. You must have the full 56-character '.onion' address before you start[2]. Write it down, bookmark it, or save it in a password manager—mistyping even one character will take you to a non-existent or entirely different service. If you do not yet have a specific address, How to Find the Dark Web: A Step-by-Step Guide explains where to locate verified directories and known onion services.

Is Using Tor Legal?

Germany's Federal Office for Information Security states that browsing the dark net alone is not illegal, and you become a criminal only when you consume or download illegal content or purchase illegal goods and services[4]. What is illegal outside the internet remains illegal on the internet, regardless of whether it is on the clearnet or the dark net[4]. Using Tor Browser and visiting '.onion' sites is legal in most countries, including the United Kingdom, the United States, and the European Union. The technology itself is neutral; your actions determine legality.

How to Open and Verify a Tor Site Safely

Opening a Tor site requires four steps: install Tor Browser, connect to the Tor network, enter the '.onion' address, and wait for the connection to establish. Each step takes longer than browsing the clearnet, and understanding what happens at each stage helps you recognise when something is wrong.

Install and Launch Tor Browser

Download Tor Browser only from https://download.torproject.org/[3]. The current stable release is version 16.0, available for Windows, macOS, and Android[9]. After installation, launch the application. You will see a 'Connect' button on the start screen. Click it and wait while Tor Browser builds a circuit through the Tor network—this typically takes 10 to 60 seconds, depending on your internet speed and the availability of relays. Do not close the window during this process; the browser is selecting three volunteer-run relays to route your traffic.

Enter the Onion Address

Once connected, you will see a modified Firefox interface with a purple onion icon in the address bar. Type or paste the full 56-character '.onion' address into the bar[2]. Do not use a search engine to find the address; search results can include phishing links that mimic legitimate services. If you copied the address from a trusted source, paste it exactly as written—one wrong character will send you to a non-existent or different service.

Wait for the Longer Connection Time

Tor sites take longer to load than regular websites because your connection is routed through multiple relays and the onion service itself is hidden within the Tor network[1]. A typical page load can take 5 to 30 seconds, and some sites may take longer if the service is under heavy load or the hosting relay is slow. Do not refresh the page immediately; give it at least 30 seconds. If the connection fails, you will see a 'Unable to connect' error or a blank page.

Verify the Onion Address Before You Trust It

The '.onion' URL encodes a cryptographic public key, so Tor automatically verifies you are connecting to the authentic service and that the connection is not being tampered with[2]. However, Tor cannot verify that the address you typed is the correct address for the service you intended to visit. Phishing sites can register similar-looking addresses or distribute fake links through forums and social media.

To verify an onion address:

  • Check the Tor Project's official lists – The Tor Project maintains a support page listing known onion services, including DuckDuckGo's onion search engine and SecureDrop instances run by news organisations.

  • Look for public announcements – Legitimate organisations publish their '.onion' addresses on their clearnet websites or official social media accounts. For example, The New York Times and ProtonMail announce their onion mirrors on their main websites.

  • Compare with multiple sources – If you find an address in a directory such as The Hidden Wiki, cross-check it against the organisation's clearnet site or a second trusted directory before entering any credentials or personal information.

What Happens If a Link Fails to Load

If you type an address and see 'Unable to connect' or 'Onionsite Not Found', three scenarios are possible:

  1. The address is incorrect – You mistyped one or more characters. Copy and paste the address again from your original source.

  2. The service is offline – Onion services can go offline at any time. The operator may have shut down the server, moved to a new address, or be experiencing technical problems. Wait a few hours and try again.

  3. Your Tor circuit is blocked – Some onion services restrict access by geography or relay type. Click 'New Circuit for this Site' in the Tor Browser menu and try again.

If you see a certificate warning—a yellow or red screen stating 'Your connection is not secure'—do not proceed. Tor sites use '.onion' addresses that do not require traditional SSL certificates, so a certificate warning usually indicates a misconfigured service or an attempt to intercept your connection. Close the tab and verify the address through an independent source before trying again.

You are now ready to browse. Tor verifies the cryptographic integrity of the connection[2], but you must verify the address matches the service you intended to visit.

Typical Mistakes When Exploring Tor Sites

Most problems people encounter when visiting Tor sites are avoidable. They stem from treating the dark web like the clearnet, skipping verification steps, or trusting unvetted sources. Below are the most common mistakes, why they matter, and what to do instead.

Downloading Tor Browser from Unofficial Sources

The safest way to download Tor Browser is from the official Tor Project website at https://download.torproject.org/, where the connection is secured using HTTPS[3]. Downloading from third-party mirrors, app stores, or torrent sites exposes you to modified versions that may contain malware, tracking code, or backdoors. These compromised builds can log every site you visit, steal credentials, or disable anonymity protections before you even open your first '.onion' link.

Each file on the official download page includes an OpenPGP signature file with the '.asc' extension that lets you verify the package was generated by the developers and has not been tampered with[10]. If you already installed Tor Browser from an unofficial source, uninstall it, delete all associated files, and download version 16.0 or later directly from the Tor Project[9].

Logging into Personal Accounts on Unknown Onion Services

Entering your email address, social media credentials, or payment details on an unfamiliar onion service links your real identity to your Tor session. If the site is a phishing clone or logs user data, your anonymity is compromised. The '.onion' URL encodes a cryptographic public key that Tor uses to verify the connection is not being tampered with[2], but Tor cannot verify that the address you typed is the correct address for the service you intended to visit.

Before entering any credentials, verify the onion address against the organisation's clearnet website or an official announcement. For example, ProtonMail and The New York Times publish their '.onion' addresses on their main websites. If you cannot find independent confirmation, do not log in. Create a new account with a pseudonymous email address instead, or use the service without authentication if possible.

Enabling Browser Plugins or Maximizing the Window

Tor Browser disables plugins such as Flash, Java, and QuickTime by default because they can leak your real IP address or execute code outside Tor's protection. Enabling them manually—by clicking 'Allow' on a plugin prompt or installing extensions—breaks anonymity. Similarly, maximizing the Tor Browser window or resizing it to fill your screen reveals your monitor resolution, a fingerprint that can help track you across sessions.

Keep Tor Browser at its default window size and do not install any extensions, even those marketed as privacy tools. If a site demands a plugin to function, assume the site is either poorly designed or actively hostile to anonymity, and leave.

Assuming Every Onion Site Is Anonymous by Default

Visiting a '.onion' site through Tor Browser hides your IP address from the service, but it does not make your behaviour anonymous. If you log into an account tied to your real name, pay with a credit card, or upload a document containing metadata with your name or location, you have identified yourself. Tor protects the connection; you must protect the content.

Before submitting any information, ask: does this action link my Tor session to my real identity? If the answer is yes, either use a pseudonym and disposable credentials, or do not submit the information at all.

Treating Random Onion Link Lists as Trustworthy

Directories such as The Hidden Wiki and similar aggregator sites are user-edited and contain a mix of legitimate services, outdated links, and phishing clones. A link that worked last month may now point to a scam site with a similar name. CISA notes that many people use the dark web for legitimate reasons such as political dissidence and private communication[7], but that does not mean every listed service is safe or honest.

Cross-check every address against the organisation's clearnet site or a second trusted directory before visiting. If you cannot verify the address independently, treat the link as untrusted. Do not enter credentials, download files, or make purchases until you have confirmed the service is authentic. How to Find the Dark Web: A Step-by-Step Guide explains where to locate verified directories and known onion services.

What You Can Realistically Expect to Find

Most Tor sites serve mundane purposes: mirrors of clearnet services, privacy tools, whistleblower platforms, and discussion forums. The landscape is less dramatic than popular culture suggests, and a large proportion of onion services are abandoned, offline, or short-lived. Understanding what actually exists helps you set realistic expectations and avoid wasting time on dead links.

Privacy-Focused Mirrors of Clearnet Services

Many organisations run onion versions of their public websites to offer visitors an additional layer of privacy. DuckDuckGo operates an onion search engine, ProtonMail provides an onion mirror of its webmail interface, and The New York Times publishes an onion version of its news site. These mirrors function identically to their clearnet counterparts but route all traffic through the Tor network, so the service never sees your IP address.

Onion mirrors are useful when you want to access a familiar service without revealing your location or when your internet provider blocks the clearnet version. The Tor Project publishes a list of known onion services on its support pages, including links to SecureDrop instances run by news organisations such as The Guardian and The Washington Post. SecureDrop is a whistleblower submission system that lets sources upload documents anonymously; each participating newsroom operates its own onion service with a unique '.onion' address[1].

Forums, Marketplaces, and Community Platforms

Discussion boards and marketplaces make up a significant portion of active onion services. Some forums focus on privacy advocacy, software development, or political dissent in countries with restrictive internet policies. CISA notes that many people use the dark web for legitimate reasons such as political dissidence and private communication, not only for cybercriminal activity[7].

Other forums and marketplaces host illegal content or facilitate the sale of prohibited goods. Germany's Federal Office for Information Security (BSI) states that browsing the dark net alone is not illegal, but you become a criminal when you consume or download illegal content or purchase illegal goods and services[4]. What is illegal outside the internet remains illegal on the internet, regardless of whether it is on the clearnet or the dark net[4].

Link Rot and Downtime Are Common

Onion services frequently go offline without notice. Operators may shut down servers, move to new addresses, or abandon projects without updating directories. You will encounter 'Onionsite Not Found' errors regularly, even for addresses that worked days earlier. This is normal. Unlike clearnet domains—which require annual renewal and DNS registration—onion addresses are free and automatically generated[2], so there is no financial or administrative barrier to creating and discarding them.

If a link fails to load, wait a few hours and try again. If the service remains offline for several days, assume it has moved or closed. Do not assume a dead link indicates censorship or a takedown; most onion services simply stop operating when the person running them loses interest or can no longer afford hosting.

Safety Boundaries That Apply to Every Tor Site

Tor Browser hides your network location from the sites you visit, but it does not protect you against malware, phishing, or voluntary self-identification. The '.onion' URL encodes a cryptographic public key that Tor uses to verify the connection is not being tampered with[2], yet this verification applies only to the transport layer. If you download a malicious file, enter credentials on a phishing clone, or share personal identifiers in a message, Tor cannot undo that action. The following practices are non-negotiable for every onion service you visit.

Never Disable Tor Browser's Security Settings

Tor Browser ships with a security level selector in the shield icon menu, offering Standard, Safer, and Safest modes. Standard mode allows JavaScript and most web features; Safer disables JavaScript on non-HTTPS sites and blocks some fonts and icons; Safest disables JavaScript entirely, along with video and audio playback. Lowering the security level to make a site 'work better' re-enables features that can execute code outside Tor's protection, leak your real IP address, or fingerprint your device.

Keep the security level at Safer or Safest when visiting unfamiliar onion services. If a site demands JavaScript to function and you cannot verify its authenticity, leave the site. Do not install browser extensions, enable plugins, or override certificate warnings. Each exception you make increases the risk that a hostile service will identify you or compromise your device.

Never Download and Open Files from Untrusted Onion Sites

Downloading a PDF, executable, or archive from an unknown onion service exposes you to malware that can log keystrokes, exfiltrate files, or establish a persistent backdoor. Tor routes your connection through the network, but once a file is on your device, it runs outside Tor's control. Opening the file in your default application—especially on your primary operating system—can reveal your real IP address if the malware initiates a direct connection to an attacker-controlled server.

If you must download a file, verify the onion address against an independent source first. Open the file in a disposable virtual machine or a separate device that does not contain personal data. Do not open downloaded files on the same system where you store work documents, photos, or credentials. Treat every download as potentially hostile until you have confirmed both the source and the file's integrity.

Avoid Sharing Personal Identifiers

Tor protects the connection, but you must protect the content. Typing your real name, home address, email address tied to your identity, or payment card number into a form on an onion service links your Tor session to your real-world identity. If the service logs submissions, shares data with third parties, or is operated by law enforcement, your anonymity is gone.

Before submitting any information, ask: does this action connect my Tor session to my real identity? If the answer is yes, use a pseudonym, a disposable email address, and a payment method that does not reveal your name or location. If you cannot submit the information anonymously, do not submit it at all.

Treat Every Site as Potentially Monitored

The Tor network hides your IP address from the onion service, but it does not guarantee that the service itself is trustworthy. An onion site can be operated by a scammer, a data broker, or a law enforcement agency running a honeypot to collect information about visitors. Entering credentials, uploading files, or making purchases on an unverified site hands that data directly to the operator.

Cross-check every onion address against the organisation's clearnet website or a second trusted source before interacting with the site. If you cannot verify the address independently, assume the site is hostile. Do not log in, do not download files, and do not make purchases. How to Access the Dark Web: A Step-by-Step Guide covers verification steps and known onion services you can use as starting points.

Legal Context and When Tor Use Becomes a Problem

Downloading and using Tor Browser to visit onion services is legal in the United Kingdom, the United States, and most other jurisdictions. Germany's Federal Office for Information Security states that browsing the dark net alone is not illegal[4]. You become a criminal only when you consume or download illegal content or purchase illegal goods and services[4]. The software itself is a privacy tool; what matters is how you use it.

What is illegal outside the internet remains illegal on the internet, regardless of whether the activity takes place on the clearnet or the dark net[4]. Tor does not grant immunity from prosecution. If you buy controlled substances, access child exploitation material, commit fraud, or engage in any other criminal act through an onion service, you are breaking the law. Law enforcement agencies monitor Tor traffic, operate honeypot sites, and have successfully prosecuted individuals who assumed the network made them untraceable.

Where Tor Is Restricted or Blocked

Some countries restrict or block access to the Tor network. China, Iran, and Turkmenistan employ deep-packet inspection to detect and disrupt Tor connections, forcing users to rely on bridge relays that are harder to identify. Russia has attempted to block Tor entry nodes, though the network's design makes complete blocking difficult. In these jurisdictions, downloading Tor Browser or connecting to the network may attract scrutiny from authorities, even if you are not engaging in illegal activity.

If you live in a country where Tor is restricted, check local laws before installing the software. Using Tor for privacy-focused research or to access blocked news sites may be technically legal but still draw unwanted attention. The Tor Project provides bridge relays and pluggable transports designed to circumvent censorship, but these tools do not eliminate the risk of detection. Assess whether the benefit of using Tor outweighs the potential consequences in your specific legal and political environment.

Documented Cases Illustrate Principles, Not Guarantees

Law enforcement agencies have dismantled dark web marketplaces, arrested operators of illegal onion services, and identified users who made operational security mistakes. These cases demonstrate that Tor protects your network location but does not protect against poor judgement, reused credentials, payment methods tied to your real identity, or voluntary disclosure of personal information. A single mistake—logging into a personal email account, using the same username across clearnet and onion sites, or making a purchase with a traceable payment method—can unravel anonymity.

Do not assume Tor provides blanket protection. If you are considering an action that is illegal in your jurisdiction, the network will not shield you from consequences. Use Tor for legitimate privacy purposes: reading news, communicating without surveillance, or accessing services that respect your anonymity. Avoid illegal activity entirely, and remember that the software is a tool, not a legal defence.

How to Check Whether a Tor Site Is Still Active

Many onion addresses disappear without warning. Operators shut down servers, abandon projects, or move to new addresses, leaving no redirect or explanation. You will encounter 'Onionsite Not Found' errors regularly, even for addresses that worked days earlier. Unlike clearnet domains—which require annual renewal and public registration—onion addresses are automatically generated and cost nothing to create or discard[2], so there is no administrative barrier to abandoning them.

When a link fails to load, wait a few hours and try again. Tor relays occasionally experience congestion, and temporary outages are common. If the service remains offline for several days, assume it has moved or closed. Do not assume a dead link indicates censorship or a takedown; most onion services simply stop operating when the person running them loses interest or can no longer afford hosting.

Verify Addresses Through Official Clearnet Pages

The safest way to confirm an onion address is still active is to check the organisation's official clearnet website. Legitimate projects—news outlets, privacy tools, whistleblowing platforms—publish their current .onion addresses on their main site, often in a dedicated 'Tor' or 'Privacy' section. The BBC, ProPublica, and the Tor Project itself list their onion mirrors this way, updating addresses when they change.

Visit the clearnet site through a standard browser, note the published onion address, then copy it into Tor Browser. Do not rely on your memory or a saved bookmark; verify the address every time you visit. If the clearnet site no longer lists an onion mirror, the service has likely discontinued it.

Use the Tor Project's Community Resources

The Tor Project maintains a support portal and community forums where verified onion services are discussed. Tor Metrics, the project's public statistics site, does not list individual onion addresses but provides aggregate data that can help you understand network health and relay availability. The project's official blog occasionally highlights new onion services from trusted organisations.

Do not treat these resources as exhaustive directories. They document known, reputable services but do not track every onion site. If you cannot find an address through the Tor Project's channels or the organisation's own clearnet site, treat the link as unverified.

Avoid Third-Party 'Dark Web Link' Aggregators

Websites and forums that compile lists of onion addresses—often marketed as 'dark web directories' or 'onion link collections'—are frequently outdated, unmoderated, and filled with phishing clones. Many aggregators list addresses without verifying ownership, allowing scammers to submit fake mirrors of popular services. Clicking a link from an aggregator can land you on a phishing site designed to steal credentials or install malware.

If you must consult a directory, cross-check every address against the organisation's official clearnet page before visiting. Never enter credentials, download files, or make purchases based solely on a third-party listing. The risk of encountering a malicious clone far outweighs the convenience of a curated list.

What to Do When an Address Stops Working

If an onion service you previously used no longer loads, search the organisation's clearnet site for an updated address. Check the Tor Project's blog or support forum for announcements. If you find no official update, assume the service has closed. Do not search for alternative addresses on aggregator sites or forums; you are more likely to find a phishing clone than a legitimate replacement.

When a service moves to a new onion address, the operator will typically announce the change on their clearnet site or through a signed message. If you see no such announcement, treat any 'new' address you encounter as untrusted until you can verify it independently.

Before You Click: Common First-Time Mistakes and Safer Alternatives

Typical Mistakes and Misconceptions

Assuming Tor Browser Makes You Anonymous Everywhere

Tor Browser routes your traffic through three relays and hides your IP address from the sites you visit. That protects your network location, but it does not protect against mistakes you make on the site itself. Logging into a personal email account, entering your real name, or reusing a username from clearnet forums ties that onion session directly to your identity. The network cannot save you from poor operational security.

Think of Tor as a privacy tool, not an invisibility cloak. If you voluntarily hand identifying information to a site operator, that operator now knows who you are regardless of how you connected. Use a pseudonym, a disposable email address, and assume every form field is being logged.

Believing Onion Addresses Are Human-Readable or Memorable

An onion address consists of 56 letters and numbers followed by '.onion'[2]. The string is automatically generated and looks random, which means you cannot glance at it and know whether it belongs to a legitimate service. Many first-time users try to remember an address or type it from memory, then land on a phishing clone with a similar-looking string.

The address is essentially a random-looking number used as a public key[5]. This design gives you cryptographic verification that you are connecting to the right location[2], but only if you compare the full address character-by-character against a trusted source. Never trust an address because it 'looks right' or because someone pasted it in a forum.

Skipping Verification of the .onion Address

Most people find an onion link on a forum, social media post, or aggregator site and click it without checking whether it actually belongs to the organisation it claims to represent. This is the single most common way first-time users land on phishing copies. A fake mirror of a marketplace or email service can look identical to the real thing while capturing everything you type.

Before interacting with any onion service, cross-check the address against the organisation's official clearnet website or a second trusted source. If you cannot verify the address independently, assume the site is hostile. Do not log in, do not download files, and do not make purchases.

Confusing 'Deep Web' with 'Dark Web' and Assuming Both Are Illegal

The deep web includes anything not indexed by search engines and requiring credentials, such as your bank account portal or a private work intranet[7]. The dark web is a subset of the deep web that requires special software like Tor Browser, and all Tor URLs end in '.onion'[7]. These are different things, and neither is inherently criminal.

Germany's Federal Office for Information Security states that browsing the dark net alone is not illegal[4]. Many people use it for legitimate reasons such as political dissidence and private communication[7]. What is illegal outside the internet remains illegal on the internet, regardless of whether it happens on the clearnet or the dark net[4]. The legal risk comes from your actions, not from the network itself.

Expecting Onion Sites to Be as Stable as Clearnet Sites

Onion addresses are automatically generated and cost nothing to create or discard[2]. Unlike clearnet domains, which require annual renewal and public registration, there is no administrative barrier to abandoning an onion service. Operators shut down servers, lose interest, or move to new addresses without leaving a redirect. You will encounter 'Onionsite Not Found' errors regularly, even for addresses that worked days earlier.

When a link fails to load, wait a few hours and try again. Temporary congestion on the Tor network is common. If the service remains offline for several days, check the organisation's clearnet site for an updated address. If you find no official update, assume the service has closed. Do not search for alternative addresses on aggregator sites; you are more likely to find a phishing clone than a legitimate replacement.

Believing Tor Protects You from Malware or Malicious Site Operators

Tor encrypts your traffic and hides your IP address, but it does not scan files for malware or prevent a site from running malicious scripts in your browser. Downloading a file from an onion service and opening it on your main system can compromise your device, your personal data, and any accounts stored on that machine. The operator of a malicious onion site can also exploit browser vulnerabilities to attempt to deanonymize you.

Treat every download from an onion service as hostile until you have verified its source and integrity. Open files in a disposable virtual machine or a separate device that contains no personal information. Keep Tor Browser updated to the current stable release, which is version 16.0 as documented by the Tor Project[9]. The browser's security settings can be raised to disable JavaScript and other active content on sites you do not trust.

Common questions

Is Tor a good browser?

Tor Browser is good for a specific job: hiding your network location and accessing .onion sites. It routes traffic through three relays and is built on Firefox, but it is not a general-purpose browser for everyday speed or convenience. If you need privacy from network observers and the sites you visit, it is a solid choice; if you want fast browsing with all extensions and logins, a standard browser works better. The current stable release is version 16.0 for Windows, macOS, and Android[9].

What is a Tor?

Tor is a network that routes your internet traffic through multiple relays so the site you visit does not see your real IP address. The name stands for The Onion Router, and the Tor Browser is the software you use to connect to that network. Onion services are sites that only work over Tor, using the special-use top-level domain '.onion' instead of .com or .net[1]. The Tor Project maintains the browser and the network, and you can download the browser from the official site at https://download.torproject.org/[3].

What are some Tor sites?

The BBC, ProPublica, and the Tor Project itself publish onion mirrors on their main clearnet sites, usually in a dedicated 'Tor' or 'Privacy' section. You should get addresses from those official pages rather than from third-party directories, because onion addresses are 56-character strings that are easy to fake[2]. The Tor Project's support portal and community forums also discuss verified onion services, but they do not maintain an exhaustive directory. If an organisation does not list an onion mirror on its clearnet site, treat any address you find elsewhere as unverified.

What is the dark web?

The dark web is the part of the internet that requires special software like Tor Browser to access, and all Tor URLs end in '.onion'[7]. CISA distinguishes it from the surface web, which is indexed by Google, and the deep web, which includes things like your bank account portal that need credentials but no special software[7]. The FBI defines the DarkNet as a subset of the deep web consisting of overlay networks that use the public internet but require unique software, configuration, or authorization to access, with access designed to hide the user's identity[11]. Many people use it for legitimate reasons such as political dissidence and private communication, not only for cybercriminal activity[7].

Are onion sites dangerous?

Onion sites are not dangerous by default, but the lack of central oversight means you are more likely to encounter phishing clones and malicious operators than on the clearnet. The .onion address itself gives you cryptographic verification that you are connecting to the right location[2], but only if you compare the full 56-character string against a trusted source[2]. The main risks come from entering personal information, downloading files to your main system, or clicking unverified links from aggregator sites. Treat every download as hostile until you have verified its source and integrity, and keep Tor Browser updated to the current stable release[9].

Key Takeaways

  • Tor hides your network location, not your mistakes. Logging into personal accounts or entering your real name still ties the session to your identity.

  • Onion addresses are 56-character strings that are easy to fake. Cross-check the full address against a second trusted source before you interact with any service.

  • Treat every download from an onion site as hostile until you have verified its source and integrity. Open files in a disposable virtual machine or separate device.

  • Browsing the dark net alone is not illegal, but what is illegal offline remains illegal on the dark net. The legal risk comes from your actions, not the network.

  • Expect onion sites to disappear without warning. If a link fails for several days and the organisation's clearnet site shows no update, assume the service has closed.

Start by installing Tor Browser from the official site and visiting only onion mirrors listed on organisations' clearnet pages. For a practical walkthrough of your first session, see How to Access the Dark Web: A Step-by-Step Guide.
