Watch an ethical hacker provide a tour of the dark web

Accessing the dark web is legal in the US, the EU, and most countries worldwide

As long as users do not pay for illegal goods or services or acquire illegal content, they cannot be prosecuted. Those on the dark web include academics, researchers, and cybersecurity experts gathering threat intelligence on cybercriminals, cyberterrorists, and state actors, as well as protesters, activists, and grassroots organizers.

The dark web can expose anonymous users to potentially dangerous environments

Browsing the dark web requires onion routing, which prevents visitors from being identified and the locations from which they connect from being traced. This has been useful to activists in environments affected by political oppression or instability. However, those unfamiliar with navigating the space may encounter malware and network attacks from denizen hackers.

Trudging through the dark web to expose child abuse

A computer expert who created a system to track down sources of revenge porn and an investigative journalist joined forces to investigate digital abuse. Their investigations focused on so-called clear nets, websites that make up the web most users surf. Then, they turned their investigation toward the dark web, where they found a child abuse website with more than 1 million registered users.

Credit monitoring services may oversell the benefits of dark web monitoring

Currently, technology exists to scrape and download data from webpages, which can then be analyzed to identify a user's information. However, scrapers cannot access or remove personal data from dark websites because they are often protected by paywalls, rendering monitoring ineffective beyond reporting publicly available data breaches.

The dark web cannot be stumbled upon by accident

Many pages on the dark web are not publicly broadcast and are available only to relevant parties on a need-to-know basis. Although some online directories list the URLs for these webpages, connecting to them still requires specialized software, as these pages block connections from traditional web browsers such as Chrome.

The dark web makes up about 0.01% of all the data on the internet

The surface web (5%-10%) consists of indexed sites—those traditional search engines have visited and stored so users can discover them via web search. The remaining 90%-95% makes up the deep web, which is not indexed and includes email and banking portals that require login credentials. The dark web is unindexed and requires anonymizing software to visit.

Explore content on the dark web safely with the Ahmia search engine

Endorsed by the Tor project, the 501(c)(3) research-education nonprofit responsible for the software needed to navigate the dark web, Ahmia allows users to search known onion sites while blocking illegal and harmful content. Through the search engine, activists can learn where to anonymously send files to media outlets.

Fraud and identity theft are among the most common dark web-related crimes

Credit card information, driver's license or passport scans, and login credentials are among the data bought and sold on dark web marketplaces, which can appear there without users' knowledge through data breaches. Medical records can fetch higher sums of money for their potential use in blackmail and insurance fraud.

Explore metrics on the Tor network, the infrastructure of the dark web

While internet traffic within the network is concealed, public, nonsensitive data can be used to estimate the number of active users, the number of relay servers, network performance speed and reliability, etc. Researchers can use this data to indirectly identify political upheavals or censorship campaigns worldwide, such as the Arab Spring.

How to catch a TikTok thief

Someone took a 10-second clip of a parody video made by Hugh Clegg and posted it to TikTok, where it racked up millions of views. The uncredited clip meant viewers assumed it was owned by the uploader, an assumption Clegg was eager to rectify. His messages and comments had no real effect outside of earning him temporary bans for "spamming." So he decided to moonlight as a private eye.
