If yous've paid any attending to online marketplaces for illegal goods like the now-defunct Silk Road or the FBI's investigations into criminal in cyberspace, chances are you've heard the term "dark web." Curious about what it means? You've come up to the right place.

The dark web is sometimes called onionland because of its content accessible only using services like Tor. The rest of the internet is simply referred to equally the clearweb, since it isn't mostly encrypted.

How does the dark spider web piece of work?

The dark web works just about the aforementioned as the regular internet: it uses the same TCP/IP framework to transmit HTTP and FTP traffic within and between networks, over the same phone, cable or FiOS lines that carry regular cyberspace traffic. Content on the dark web consists of HTML webpages and their avails, merely like it does on the residuum of the web. In fact, under the hood, the dark web is the aforementioned as the regular web, with two of import exceptions that as well distinguish the dark web from the deep spider web.

Kickoff: the dark spider web isn't indexed by search engines. Second, content on the nighttime web can't exist accessed with regular web browsing software alone; additional software is required to make the networks talk to one another.

This is considering content on the dark spider web is hosted on overlay networks, which are physically connected to the internet but aren't accessible to web crawlers. That relative inaccessibility is considering the night spider web uses a complete, but fundamentally different, network addressing organization than the web addresses most of us know and use. Browsers like Chrome and Firefox are programmed to access website files using the DNS index, which turns a file's unique address on its unique server into a cord of text that you can type into your address bar. Sites indexed by the DNS registry are accessible via top-level domains like .com and .org, among others. After ICANN opened up the suffixing organization to other strings of text, we started to see web addresses that await like home.cern and bit.ly — simply you lot can still type those into your accost bar and go to a website, considering they're in the official DNS registry. Dark websites don't participate in the DNS system, and web crawlers don't have the software to get onto the night web, so the dark web and the clearweb don't really cross-pollinate.

Content obscured in this manner can notwithstanding be accessed, merely you need the right software. It's a bit like a Wi-Fi network that doesn't circulate its SSID: you tin only get access if yous already know exactly how to detect it. Some content accessible merely through Tor is hosted at a .onion pseudo-acme-level domain, which means that in the right software, y'all might type in foobar.onion and go to the Foobar dark website.

Such software, including the Tor browser parcel, is capable of bridging the differences in network behavior between the dark web and the clearweb. But that only works when you're using a uniform browser and have the right encryption. Tor, Freenet and I2P are the most commonly cited examples of software capable of accessing the nighttime web. Typing a .onion accost into your Chrome address bar won't go you anywhere. Furthermore, many if non most .onion sites are generated 16-character "non-mnemonic" alphanumeric strings, rather than beingness composed of words like most clearweb URLs.

There besides exists a divergence in the path web traffic takes on the clearnet versus the dark web. Tor is valuable because it sends your ain web traffic through multiple different network nodes, masking its origin and destination. There'southward significant overlap between VPNs and the dark web; both services use encryption and multiple network nodes to anonymize traffic. But VPNs deal with clearweb sites that participate in the DNS system, while nighttime spider web browsers deal with domains non recognized past ICANN.

What is the dark web used for?

The structure of the dark web makes it anonymizing, which ways that outset and foremost, information technology'south used for bearding communication and web browsing. This accounts for the vast majority of network traffic through Tor. Why seek out anonymity? To read and write virtually things that might become you in trouble, like political dissent or whistleblowing. The same technology that enables Tor is capable of tunneling out from behind the Great Firewall of China, and the US government contributes to the development of such software.

Anonymity likewise brings out those who wish to do illegal things. A 2022 written report found that of the dissimilar kinds of sites on the dark internet, there are more markets devoted to drugs and guns than whatever other kind of dark site, including forums, bitcoin laundering, hacking, fraud, whistleblowing and even regular sometime porn.

To paraphrase Jim Jeffries, if you want to murder someone, you lot can't just walk upwardly to Pier 31 and shout "GUNS, WHO WANTS TO SELL ME SOME GUNS!?" Simply with a website similar an evil eBay that lists weapons and other contraband for sale, all of a sudden y'all don't have to know someone with "black marketplace connections." You just have to exist able to install some software.

Tor hidden services are the other thing the dark web does, and they're what gives the night web its shady reputation. Subconscious services refers to dark sites where both the host and the visitor are anonymous to one some other. That engineering enables nighttime web sites that host illegal content to persist. Hidden services account for only one.5% of the Tor network book. But the overwhelming majority of resources requested over Tor hidden services — fully lxxx% of that traffic — were requests from child corruption sites. Approachable traffic from the dark web flowed mainly between botnets and their hidden control servers. More detail on Tor's traffic patterns and how much of its total bandwidth is used for illegal activities is available in a web log post by the Tor project.

The dark web is notoriously dodgy territory for both buyers and sellers. Law enforcement has been chipping abroad at the nominal anonymity afforded by software like Tor, and anything of involvement on the night web is as likely to be a scam as it is to be a honeypot. Between social engineering and software vulnerabilities, information technology is a realm best accessed while wielding some trustworthy anti-malware.

For a long time, the Silk Road was the biggest game in darknet commerce. It allowed users to sell a great many illegal things, and inspired a number of similarly designed copycat markets. Transactions there were conducted in bitcoins and other virtual currency, then goods were shipped through the mail. Just a high-profile bust and ensuing courtroom case put several Silk Route admins in jail. The media spotlight has impinged on the Silk Route's relative obscurity, reducing its value as a black market.

While Uncle Sam contributes to the evolution of Tor and like anonymity resources, the government is as well known to take more of a proprietary approach, considering even the dark web to exist within American jurisdiction when site hosting is in question. The FBI paid Carnegie Mellon to crack Tor in pursuit of a criminal example. They even waded into the muck and ran a huge sting functioning on Playpen, a darknet child porn site — by taking over control of the site and running information technology for weeks as a poisoned well to catch its users.

The dark cyberspace is an excellent example of how difficult information technology is to foreclose criminals from using anonymizing services designed to protect honest dissenters. Tor'southward anonymizing functions are critically important to people who rely on information technology to discuss sensitive topics without fear of reprisal. The debate over how much light should be shone into the nighttime spider web is an ongoing topic of discussion. How much illegal activity should be allowed to maintain Tor's positive benefits, and is there a way to unmask kid molesters and other illicit activity without compromising the security that makes the night web work?
