More specifically, we used darknet site search engines (such as Recon, Darknet live, Dark Eye, dark.fail, and DNStats 21,22) to search underground marketplaces and forums and then manually validated their activeness. In our study, we only selected marketplaces with more than 30 opioid listings. In this way, we gathered 5 active underground marketplaces with opioid listings. Note that some high-profile underground marketplaces and forums are frequently deactivated or have been shut down by law enforcement authorities 23. Hence, we also gathered snapshots of 5 underground marketplaces and 6 forums collected by the anonymous marketplace archives programs and previous research projects 20.
The Invisible Majority: People Whose Drug Use Is Not Problematic
This section elaborates on the methodology used to identify opioid trading information in the anonymous market and forums. Specifically, we collected approximately 248,359 unique listings and 1,138,961 unique forum traces (ie, threads of posts) from 10 anonymous online marketplaces and 6 forums. We then identified 311 opioid keywords and jargons to recognize 28,106 listings and 13,508 forum traces related to underground opioid trading activities. Finally, we used natural language processing techniques to extract opioid trading information to characterize underground opioid commodities, suppliers, and transactions. We first conducted a whole-site crawl of anonymous online marketplaces and forums to solicit data. We aimed to profile the opioid supply chain in anonymous markets and forums via a large-scale, longitudinal measurement study on anonymous market listings and posts.
Harm Reduction Services And Safe Injection Sites
After perusing the items available on the anonymous online market (step 5), the buyer will add opioids to their shopping cart (step 6). When the buyer wants to check out and make a purchase using cryptocurrency (eg, Bitcoin), if the trader accepts payment through an anonymous online marketplace as an escrow, the buyer will place the listed amount of cryptocurrency in escrow (step 7). Then, the trader receives the order and escrow confirmation (step 8). Otherwise, the buyer will pay the trader directly using cryptocurrency or any other payment method accepted by the trader (step 9) 7. Note that the escrow mechanism is widely deployed in the anonymous online market because it helps to build trust and resolve disputes between sellers and buyers. When the purchase is made, the opioid trader ships the purchased item to the buyer (step 10).
AI, Shadow AI, And Phishing: 5 Takeaways From IBM 2025 Data Breach Report

From our measurement, we concluded that anonymous online marketplaces and forums provided easy-access platforms for global opioid supply. This paper seeks to complement current studies widening the understanding of opioid supply chains in underground marketplaces using comprehensive, large-scale, longitudinal anonymous marketplace and forum data. To this end, we propose a series of techniques to collect data; identify opioid jargon terms used in the anonymous marketplaces and forums; and profile the opioid commodities, suppliers, and transactions. Specifically, we first conducted a whole-site crawl of anonymous online marketplaces and forums to solicit data. Subsequently, we conducted a comprehensive, large-scale, longitudinal study to demystify opioid trading activities in anonymous markets and forums.

For as many people who believe this is something of a utopian development, you can be sure many more view it as dystopian—especially if the dealers are in fact scammers or selling dodgy goods. A single study can’t definitively prove whether the dark web offers a safer supply. But these results suggest that, while some substances were indeed less likely to be adulterated, purchasing there is not a silver-bullet harm reduction strategy—and that testing remains vital whatever the source.
Topic Modeling Of Forum Posts
Recent years have seen quite some research into drug trade on the dark web. However, harms and benefits for buyers / consumers still remain poorly understood. As part of a Belgian university collaboration, we (two early career social scientists) aim to quantify the consequences for drug buyers that source their drugs through cryptomarkets. Do people that purchase their goods on the dark web use more, less, safer, more reckless, different substances, et cetera? Is there a significant information exchange on the dark web on safe use and potential risks? The site would be reinstated in November,6 with a revamped user interface, and remains active as of September 2022.
Reddit Bans Subreddits Dedicated To Dark Web Drug Markets And Selling Guns
By paying close attention to where adulterated substances were purchased, local drug checking services can help participants make more informed decisions to protect their health. Both the dark web and surface web offer their own risks and dangers. The dark web was built for anonymity and, as such, it’s often nearly impossible for buyers to know who they are transacting with or where their purchases are being sourced. Drugs may be adulterated, counterfeit, or possibly made by amateurs out of their homes using substandard equipment. These dangers exist on the surface web as well; however, without illicit marketplaces that have built-in escrow and rating systems, there may be a higher likelihood of nondelivery schemes and phishing scams from websites on the surface web.

Established in 2022, WizardShop is one of the biggest data stores on the dark web, focusing mainly on carding and financial data. Although the safety data I collated and researched over so many years is now literally at the fingertips of countless thousands, this remains the case. Further, no cavalry, in the form of a benevolent government or philanthropic authority, is going to appear and suddenly provide this form of education. On visiting a doctor or a pharmacy provision of safety information is routine, and this usually extends well beyond dose, frequency and duration. I don’t want to buy drugs or anything at all I just want to see the dark side of the world.
To avoid blocking from the marketplace, we provided as an input to the scraper a session cookie that we obtained by manually logging into the marketplace and solving a Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA). However, some sites, namely, the Empire Market, forced users to log out when the life span of the session cookie was expired. In addition, we set parameters such as sleeping time to limit the speed of crawling. LegitScript specializes in risk and compliance for highly regulated industries including CBD/cannabis, online gambling, cryptocurrencies, drugs, financial trading, online adult, scams and fraud, and more. The results provide insight into opioid trading in the anonymous markets and forums and may prove an effective mitigation data point for illuminating the opioid supply chain. Some dealers these days are even brazen enough to boost their posts and pay for sponsored advertising.
The dark web offers vital anonymity for vendors and buyers, who use cryptocurrencies such as Bitcoin to process transactions. In a Vice documentary on drug sales on social media, it took the host just five minutes to connect with a dealer in London. “You see little kids, 12-year-olds and everything, setting up accounts. ” As part of a separate research project, a 15-year-old was able to locate an account selling Xanax tablets in mere seconds on Instagram. With Australians finding new ways to source illicit drugs, Barratt says it was more urgent than ever to launch more drug checking services.
We developed Lunar to monitor the deep and dark web, including dark web marketplace sites. In this way, we collected 7100 promotion posts and 6408 review posts from forum posts in total. Finally, in the model refining stage, the model is trained for other 2 iterations using the same objective function. We manually investigated the results by randomly sampling 10% of data records during each iteration and adding false positive samples into the unlabeled set. The review detection model yielded a mean precision of 81.5% and an average recall of 80.1%, whereas for the promotion detection model, it yielded a mean precision of 88.1% and an average recall of 85.1% (Table 4).

Dark Web’s Longest-standing Drug Market Seized In Multinational Effort
My latest book The Darkest Web, goes beyond the darknet markets and explores the world of murder-for-hire, red rooms, child exploitation and hurtcore. Having relatively zero experience with computers, all of this was a learning curve for me. It took me several tries and long frustrating hours to finally get a grip on navigating tor. I actually ended up asking a friend who studied computer science to come over and help, as he had experience with the marketplaces.
- These dangers exist on the surface web as well; however, without illicit marketplaces that have built-in escrow and rating systems, there may be a higher likelihood of nondelivery schemes and phishing scams from websites on the surface web.
- While the method has its limitations, HugBunter argued that failure to provide a cryptographic signature alongside continued account activity could be telling.
- Imagine the potential impact this might have in terms of user safety.
- A single study can’t definitively prove whether the dark web offers a safer supply.
- “Excellent,” reads a plaudit posted by a buyer of the opiate oxycodone.
Our modification of the semantic comparison model will generate comparable word embeddings for opioid jargon words in legitimate documents (ie, benign corpora embedding) and in underground corpora (ie, underground corpora embedding). Specifically, our modification used a series of opioid keywords collected to generate their benign corpora embeddings and then searched for words whose underground corpora embeddings were close to the opioid keywords’ benign corpora embeddings. We output the top 100 proper nouns in the underground corpora in our implementation, whose embeddings showed the closest cosine distance to the known opioid keywords. Data set summary of marketplaces and forums that were collected for this study. Opponents of strict dark web policing sometimes argue that such operations drive criminal activity to even more hidden or encrypted platforms, making detection harder. They may also raise privacy and surveillance concerns, warning that aggressive cyber policies risk collateral impacts on online freedom and legitimate users of anonymity technologies.
Its affordability and reliability have earned it a loyal customer base. The platform’s activity has increased significantly over the past year, indicating its growing influence and market share in the underground economy. It is a hub for financial cybercrime and offers a wide range of illicit services and stolen data that cater to sophisticated cybercriminals. To expand their reach, some marketplaces established parallel channels on Telegram.
