Am I totally anonymous if I use Tor

Generally it is impossible to have perfect anonymity, even with Tor. Though there are some things you can practice to improve your anonymity while using Tor and offline.

Anonymity check

With this service, you can check how anonymous you are on the network, how much data provided by your computer/browser, the same data provided by your ip-address.

IP-address differences

We have detected that your real IP address is different from the one provided. Use the correct system settings, Proxy and VPN or turn off Flash/Java/ActiveX/WebRTC in the browser.

Proxy detected

We have detected that you are using a proxy. Your proxy is public, or not completely anonymous. We recommend using high-quality private proxy.

VPN detected

We have detected that you are using VPN. We recommend you to change a VPN, or use it with private proxies.

Anonymizer detected

We found that most likely you are using an Anonymizer. Most anonymizers are defined and can intercept and track your traffic. We do not recommend using them for anonymity.

Tor detected

We have detected that you are using Tor. The IP addresses of exit nodes of the Tor network are known. So it is known that you use anonymization tools and this can cause suspicion.

Different system time

The system time on your computer differs from the time defined by IP. You are possibly trying to hide through anonymization.

Different browser headers

UserAgent transmitted by your browser is different from the one we checked using Javascript. Most likely you are trying to hide your real browser.

Your IP address is blacklisted. This is a bad signal, some sites may block you because of this or forbid certain actions.

WebRTC enabled

You have not disabled WebRTC. Highly recommend to disable it because it reveals Your real IP address when using a Proxy and VPN, as well as a list of all local IP addresses behind a NAT.

Open proxy ports

We have detected that you work through proxies low level of anonymity, because he has determined the open ports.

Flash enabled

You have not disabled Flash. Highly recommend to disable it, since Flash can reveal Your real IP address.

Java enabled

You have not disabled Java. Highly recommend to disable it, because Java can reveal Your real IP address.

ActiveX enabled

You have not disabled ActiveX. Highly recommend to disable it, or to visit sites where you need it with another browser.

Am I totally anonymous if I use Tor?

Generally it is impossible to have perfect anonymity, even with Tor. Though there are some things you can practice to improve your anonymity while using Tor and offline.

Use Tor Browser and software specifically configured for Tor

Tor does not protect all of your computer’s Internet traffic when you run it. Tor only protects applications that are properly configured to send their Internet traffic through Tor.

  • Safe: Tor Browser
  • Unsafe: Any other browser configured to use Tor as a proxy
  • Safe: OnionShare
  • Unsafe: BitTorrent over Tor

Control what information you provide through web forms

If you visit a website using Tor Browser, they don’t know who you are or your true location. Unfortunately many sites ask for more personal information than they need through web forms. If you sign in to that website, they still don’t know your location but they know who you are. Further, if you provide: name, email, address, phone number, or any other personal information, you are no longer anonymous to that website. The best defense is to be vigilant and extremely cautious when filling out web forms.

Don’t torrent over Tor

Torrent file-sharing applications have been observed to ignore proxy settings and make direct connections even when they are told to use Tor. Even if your torrent application connects only through Tor, you will often send out your real IP address in the tracker GET request, because that’s how torrents work. Not only do you deanonymize your torrent traffic and your other simultaneous Tor web traffic this way, you also slow down the entire Tor network for everyone else.

Don’t enable or install browser plugins

Tor Browser will block browser plugins such as Flash, RealPlayer, Quicktime, and others: they can be manipulated into revealing your IP address. Similarly, we do not recommend installing additional addons or plugins into Tor Browser, as these may bypass Tor or otherwise harm your anonymity and privacy.

Use HTTPS versions of websites

Tor will encrypt your traffic to and within the Tor network, but the encryption of your traffic to the final destination website depends on that website. To help ensure private encryption to websites, Tor Browser includes HTTPS-Only Mode to force the use of HTTPS encryption with websites that support it. However, you should still watch the browser URL bar to ensure that websites you provide sensitive information to display a padlock or onion icon in the address bar, include https:// in the URL, and display the proper expected name for the website. Also see EFF’s interactive graphic explaining how Tor and HTTPS relate.

Don’t open documents downloaded through Tor while online

Tor Browser will warn you before automatically opening documents that are handled by external applications. DO NOT IGNORE THIS WARNING. You should be very careful when downloading documents via Tor (especially DOC and PDF files, unless you use the PDF viewer that’s built into Tor Browser) as these documents can contain Internet resources that will be downloaded outside of Tor by the application that opens them. This will reveal your non-Tor IP address. If you must work with files downloaded via Tor, we strongly recommend either using a disconnected computer, or using dangerzone to create safe PDF files that you can open. Under no circumstances is it safe to use BitTorrent and Tor together, however.

Use bridges and/or find company

Tor tries to prevent attackers from learning what destination websites you connect to. However, by default, it does not prevent somebody watching your Internet traffic from learning that you’re using Tor. If this matters to you, you can reduce this risk by configuring Tor to use a bridge rather than connecting directly to the Tor network. Ultimately the best protection is a social approach: the more Tor users there are near you and the more diverse their interests, the less dangerous it will be that you are one of them. Convince other people to use Tor, too!

Be smart and learn more. Understand what Tor does and does not offer. This list of pitfalls isn’t complete, and we need your help identifying and documenting all the issues.

Anonymity check

Trying to be anonymous on the internet? Are you using a VPN or proxy?
Check if everything you wanted to hide is really hidden.

Check method Results
Suspicious headers

Determined by the presence of http_via, via, http_x_forwarded_for, client_ip, proxy_connection, http_proxy_connection, forwarded-for-ip and other headers. An indirect indicator of the anonymization tools usage. The presence of suspicious headers does not affect your anonymity.

Suspicious ports

Determined by the presence of open proxy, vpn, http/s ports. To prevent this item from being identified, use private dedicated IP addresses on VPN servers. These IP addresses will not have open VPN/proxy ports for connection. An indirect indicator of the anonymization tools usage. The presence of suspicious ports does not affect your anonymity.

Determined by the presence of an IP-address in the torproject database. A fairly accurate indicator of the anonymization tools usage. Potentially affects your anonymity and security, since some of the output TOR nodes may belong to hackers or unreliable owners.

Two-way ping

Ping times from client to server and from the server to the client are measured. You can prevent detection by closing ping to your IP address. The ping closure service is available when renting personal dedicated IP address in our VPN. The two-way ping detection does not affect your anonymity.

Time zone discrepancy

Time zone discrepancies can occur when you set a time zone of one country, and the VPN or proxy server to which you are connected is located in a different country. Doesn’t affect your anonymity. Easily corrected by changing the time on the computer. An indirect indicator of the anonymization tools usage. Doesn’t affect your anonymity.

Suspicious IP address

Checking for one of the keywords in the hostname of the IP address: VPS, server, VPN, proxy, ISP and others. If you are using a VPN and want this item not to be detected, select another server in the hostname with no extra keywords. An indirect indicator of the anonymization tools usage. Doesnt affect your anonymity. anonymity_checker__check_method_7 = “Web pages” anonymity_checker__check_method_7_desc = Determined by the presence of a web page when accessing the IP address via http. Indicates a running web server at an IP address. May be an indirect indicator of the anonymization tools usage. Doesnt affect your anonymity.

Checked against a special online database of hosting providers. If the IP address you are using is included in this database, and you are connected to a VPN, then just use a different server.

UserAgent spoofing

Determined using a browser script that uses JavaScript to invoke functions that are present in certain browsers. A match with the UserAgent declared by the browser is checked. A discrepancy indicates the use of plugins that replace the real UserAgent. Detection of the discrepancy does not affect your anonymity.

More about the service

Anonymity check shows how other websites on the internet see you.

If you have hidden your IP address using a VPN or proxy, make sure nothing else is giving you away.

Online service checks DNS leak , tries to get real IP-address through WebRTC . Checks if your real IPv6 is visible.

Only a leak of the real IP address is critical for anonymity.

Everything else: two-way ping, open ports, headers, fingerprint, hostname of the server on the network and time zone are only indirect signs of using anonymization tools. They do not affect your privacy on the internet.

Please note that all such tests are “synthetic.” The fact is that ordinary websites do not check all of their visitors for all the signs that are used in this test. Most often, this is only an IP-address, its country, city. IPv6 and leakage via WebRTC are rarely checked.

The main purpose of this testing is to enable you to eliminate what is possible with the browser and anonymization tool you are using. Some can be easily eliminated using browser settings, others using proxy or VPN settings.
