What is the dark web? How to access it and what you'll find

[Mila Eryomina]

The dark web is part of the internet that isn't visible to search engines and requires the use of an anonymizing browser called Tor to be accessed.

Dark web definition

The dark web is a part of the internet that isn't indexed by search engines. You've no doubt heard talk of the “dark web” as a hotbed of criminal activity — and it is. Researchers Daniel Moore and Thomas Rid of King's College in London classified the contents of 2,723 live dark web sites over a five-week period in 2015 and found that 57% host illicit material. 

A 2019 study, Into the Web of Profit, conducted by Dr. Michael McGuires at the University of Surrey, shows that things have become worse. The number of dark web listings that could harm an enterprise has risen by 20% since 2016. Of all listings (excluding those selling drugs), 60% could potentially harm enterprises.

You can buy credit card numbers, all manner of drugs, guns, counterfeit money, stolen subscription credentials, hacked Netflix accounts and software that helps you break into other people’s computers. Buy login credentials to a $50,000 Bank of America account, counterfeit $20 bills, prepaid debit cards, or a “lifetime” Netflix premium account. You can hire hackers to attack computers for you. You can buy usernames and passwords.

Not everything is illegal, the dark web also has a legitimate side. For example, you can join a chess club or BlackBook, a social network described as the “the Facebook of Tor.”

Deep web vs. dark web: What’s the difference?

The terms “deep web” and “dark web” are sometimes used interchangeably, but they are not the same. Deep web refers to anything on the internet that is not indexed by and, therefore, accessible via a search engine like Google. Deep web content includes anything behind a paywall or requires sign-in credentials. It also includes any content that its owners have blocked web crawlers from indexing.

Medical records, fee-based content, membership websites, and confidential corporate web pages are just a few examples of what makes up the deep web. Estimates place the size of the deep web at between 96% and 99% of the internet. Only a tiny portion of the internet is accessible through a standard web browser—generally known as the “clear web”.

The dark web is a subset of the deep web that is intentionally hidden, requiring a specific browser—Tor—to access, as explained below. No one really knows the size of the dark web, but most estimates put it at around 5% of the total internet. Again, not all the dark web is used for illicit purposes despite its ominous-sounding name.

Dark web tools and services 

The Into the Web of Profit report identified 12 categories of tools or services that could present a risk in the form of a network breach or data compromise:

• Infection or attacks, including malware, distributed denial of service (DDoS) and botnets
• Access, including remote access Trojans (RATs), keyloggers and exploits
• Espionage, including services, customization and targeting
• Support services such as tutorials
• Credentials
• Phishing
• Refunds
• Customer data
• Operational data
• Financial data
• Intellectual property/trade secrets
• Other emerging threats

The report also outlined three risk variables for each category:

• Devaluing the enterprise, which could include undermining brand trust, reputational damage or losing ground to a competitor
• Disrupting the enterprise, which could include DDoS attacks or other malware that affects business operations
• Defrauding the enterprise, which could include IP theft or espionage that impairs a company's ability to compete or causes a direct financial loss

Ransomware-as-a-service (RaaS) kits have been available on the dark web for several years, but those offerings have become far more dangerous with the rise of specialized criminal groups like REvil or GandCrab. These groups develop their own sophisticated malware, sometimes combined with pre-existing tools, and distribute them through "affiliates". 

The affiliates distribute the ransomware packages through the dark web. These attacks often include stealing victims' data and threatening to release it on the dark web if the ransom isn't paid. 

Improperly managing your enterprise’s digital certificates can lead to security and operational risks.

This business model is successful and lucrative. IBM Security X-Force, for example, reported that 29% of its ransomware engagements in 2020 involved REvil. The criminal groups that developed the malware gets a cut of the affiliates' earnings, typically between 20% and 30%. IBM estimates that REvil's profits in the past year were $81 million.

Dark web browser

All this activity, this vision of a bustling marketplace, might make you think that navigating the dark web is easy. It isn’t. The place is as messy and chaotic as you would expect when everyone is anonymous, and a substantial minority are out to scam others.

Accessing the dark web requires the use of an anonymizing browser called Tor. The Tor browser routes your web page requests through a series of proxy servers operated by thousands of volunteers around the globe, rendering your IP address unidentifiable and untraceable. Tor works like magic, but the result is an experience that’s like the dark web itself: unpredictable, unreliable and maddeningly slow.

Still, for those willing to put up with the inconvenience, the dark web provides a memorable glimpse at the seamy underbelly of the human experience – without the risk of skulking around in a dark alley. 

Dark web search engine

Dark web search engines exist, but even the best are challenged to keep up with the constantly shifting landscape. The experience is reminiscent of searching the web in the late 1990s. Even one of the best search engines, called Grams, returns results that are repetitive and often irrelevant to the query. Link lists like The Hidden Wiki are another option, but even indices also return a frustrating number of timed-out connections and 404 errors.

Dark web sites

Dark web sites look pretty much like any other site, but there are important differences. One is the naming structure. Instead of ending in .com or .co, dark web sites end in .onion. That’s “a special-use top level domain suffix designating an anonymous hidden service reachable via the Tor network,” according to Wikipedia. Browsers with the appropriate proxy can reach these sites, but others can’t.

Dark web sites also use a scrambled naming structure that creates URLs that are often impossible to remember. For example, a popular commerce site called Dream Market goes by the unintelligible address of “eajwlvm3z2lcca76.onion.”

Many dark websites are set up by scammers, who constantly move around to avoid the wrath of their victims. Even commerce sites that may have existed for a year or more can suddenly disappear if the owners decide to cash in and flee with the escrow money they’re holding on behalf of customers.

Law enforcement officials are getting better at finding and prosecuting owners of sites that sell illicit goods and services. In the summer of 2017, a team of cyber cops from three countries successfully shut down AlphaBay, the dark web’s largest source of contraband, sending shudders throughout the network. But many merchants simply migrated elsewhere.

The anonymous nature of the Tor network also makes it especially vulnerable to DDoS, said Patrick Tiquet, Director of Security & Architecture at Keeper Security, and the company’s resident expert on the topic. “Sites are constantly changing addresses to avoid DDoS, which makes for a very dynamic environment,” he said. As a result, “The quality of search varies widely, and a lot of material is outdated.”

For sale on the dark web

The dark web has flourished thanks to bitcoin, the crypto-currency that enables two parties to conduct a trusted transaction without knowing each other’s identity. “Bitcoin has been a major factor in the growth of the dark web, and the dark web has been a big factor in the growth of bitcoin,” says Tiquet.

Nearly all dark web commerce sites conduct transactions in bitcoin or some variant, but that doesn’t mean it’s safe to do business there. The inherent anonymity of the place attracts scammers and thieves, but what do you expect when buying guns or drugs is your objective?

Dark web commerce sites have the same features as any e-retail operation, including ratings/reviews, shopping carts and forums, but there are important differences. One is quality control. When both buyers and sellers are anonymous, the credibility of any ratings system is dubious. Ratings are easily manipulated, and even sellers with long track records have been known to suddenly disappear with their customers’ crypto-coins, only to set up shop later under a different alias.

Most e-commerce providers offer some kind of escrow service that keeps customer funds on hold until the product has been delivered. However, in the event of a dispute don’t expect service with a smile. It’s pretty much up to the buyer and the seller to duke it out. Every communication is encrypted, so even the simplest transaction requires a PGP key.

Even completing a transaction is no guarantee that the goods will arrive. Many need to cross international borders, and customs officials are cracking down on suspicious packages. The dark web news site Deep.Dot.Web teems with stories of buyers who have been arrested or jailed for attempted purchases.

As in the real world, the price you pay for stolen data fluctuates as the market changes. According to Privacy Affair's Dark Web Price Index 2021, these are the most current prices for some of the data and services commonly traded over the dark web:

• Cloned credit card with PIN: $25 to $35
• Credit card details with account balance up to $5,000: $240
• Stolen online banking logins with at least $2,000 in the account: $120
• PayPal transfers from stolen accounts: $50 to $340
• Hacked Coinbase verified account: $610
• Hacked social media account: $1 to $60
• Hacked Gmail account: $80
• Hacked eBay account with good reputation: $1,000

Is the dark web illegal?

We don’t want to leave you with the impression that everything on the dark web is nefarious or illegal. The Tor network began as an anonymous communications channel, and it still serves a valuable purpose in helping people communicate in environments that are hostile to free speech. “A lot of people use it in countries where there’s eavesdropping or where internet access is criminalized,” Tiquet said.

If you want to learn all about privacy protection or cryptocurrency, the dark web has plenty to offer. There are a variety of private and encrypted email services, instructions for installing an anonymous operating system and advanced tips for the privacy-conscious.

There’s also material that you wouldn’t be surprised to find on the public web, such as links to full-text editions of hard-to-find books, collections of political news from mainstream websites and a guide to the steam tunnels under the Virginia Tech campus. You can conduct discussions about current events anonymously on Intel Exchange. There are several whistleblower sites, including a dark web version of Wikileaks. Pirate Bay, a BitTorrent site that law enforcement officials have repeatedly shut down, is alive and well there. Even Facebook has a dark web presence.

“More and more legitimate web companies are starting to have presences there,” Tiquet said. “It shows that they’re aware, they’re cutting edge and in the know.”

There’s also plenty of practical value for some organizations. Law enforcement agencies keep an ear to the ground on the dark web looking for stolen data from recent security breaches that might lead to a trail to the perpetrators. Many mainstream media organizations monitor whistleblower sites looking for news.

In addition to forums and bulletin boards dedicated to the sale of any forbidden stuff, the dark web has resources of organizations banned for various reasons (for example, the political opposition), sites devoted to investigations that are dangerous / forbidden to publish freely (for example, the ProPublica news site), online libraries, collections of interesting information and courses, torrent trackers.
