Trudging through the dark web to expose child abuse

Watch an ethical hacker provide a tour of the dark web

Cybersecurity researcher John Hammond explores the effectiveness of a dark web search engine, leaks from ransomware group data breaches, and a categorized index of dark web links, including some that are alleged to host malware. Many dark web sites are no longer active or host scams to fool unsuspecting visitors.

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.

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 protects free speech from censorship and authoritarian oversight

Encrypted networks allow users with internet access anywhere in the world to view blocked content and avoid surveillance when communicating evidence of abuse to independent journalists. The same networks can support democracies by helping activists coordinate protests on dark web forums.

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.

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.

Individuals have been convicted of ordering assassinations from the dark web

Researchers have uncovered online storefronts allegedly run by members of various mafia or hitmen that offer to harm or murder individuals in exchange for monetary payment. However, no known murder has been attributed to any of them, and cybercrime task forces believe them to be scams (warning—sensitive content).

Deepfake pornography poses significant challenges in combating sexual abuse

True crime fans can sometimes disregard the real people and trauma behind cases

True crime content has become a social gathering place. In addition to content generated by creators, consumer-driven true crime spaces have blossomed on social media. In these spaces, consumers track developments and share theories as if criminal cases are sports. Citizen sleuths can sometimes inspire new leads but often add to survivors' suffering and sling speculation that can clog tip lines and hit innocent bystanders.

Support groups may not be private and can suddenly change focus

Sexual assault survivors that had gathered on a Facebook support group were shocked when administrators suddenly changed the group into one for sharing erotica.
