With The Intercept’s new onion service for readers of our website, we’ll also join the ranks of the New York Times, ProPublica, BuzzFeed News, The Markup, and other news organizations in making their core websites available as onion services. The Intercept along with dozens of other newsrooms around the world, including pretty much every major news organization, run Tor onion sites for SecureDrop, a whistleblower submission platform. But it’s not the only use of onion services by a long shot. That stuff is, in fact, facilitated by anonymous websites running Tor onion services, just as it’s facilitated by the normal, non-anonymous internet. When people hear about the “dark web,” they tend to think about shady things like drug markets and money laundering. All the communication between Tor Browser and the web server happens in the dark. Onion services have another cool property: The connection never exits the Tor network, so there are no exit nodes involved.
All they can see is that two IP addresses are both using Tor. And the Tor nodes themselves can’t spy on anything. You can’t learn the website’s real IP address, and the website can’t learn yours either. If you load an onion site in Tor Browser, both you and the web server bounce encrypted data packets through the Tor network until you complete an anonymous connection, and no one can track anyone involved: Your ISP can only see that you’re using Tor, and the website’s ISP can only see that it’s using Tor. Instead of using normal domain names, these websites end with “.onion”. So what exactly is an onion service? Just like when people use Tor Browser to be anonymous, web servers can use Tor to host anonymous websites as well. Tor Onion Services Let Websites Themselves Be Anonymous Tor onion services do the same thing, except for websites themselves. In short, Tor Browser makes it so people can load websites anonymously. The first node can see your home IP address, because you connect directly to it, but can’t see what site you’re loading, and the last node (also called the exit node) can see what site you’re loading but doesn’t know your IP address.
And the Tor nodes themselves can’t fully track you either. Your ISP can’t see what website you’re visiting, only that you’re using Tor. The website can’t see where you’re coming from, only that you’re using Tor. Instead, your connection first bounces between three Tor nodes and then finally exits the Tor network and goes to the website. Within the network, consisting of thousands of nodes run by volunteers across the internet, you do not connect from your house directly to the web server. Even Tor itself won’t know what you’re up to. The website can see where you are coming from (and track you), and your internet service provider can see which website you’re loading (and track what you’re doing and sell advertising based on your activity).īut if you open Tor Browser and load the same website, none of those parties can spy on you. When you load a website in a normal web browser like Chrome, Firefox, Safari, or Edge, you make a connection over the internet directly from your house (or wherever you happen to be) to the web server you’re loading. Tor Browser Lets People Browse the Web Anonymously Websites that end in “.onion” are known as Tor onion services - or if you want to be dramatic about it, the “dark web.” Here’s how it all works.
