The classifier was built upon transfer learning and a crafted objective function that heavily weighs the penalty of misclassifying a positive instance. Tor is comprised of people from all over the planet who are donating their computers to the network. Bouncing your request around to random computers all over the world makes it much harder for people to find you. Let’s say you’re in New York and you want to search a site hosted in New Jersey. Instead of connecting you directly, the Tor browser takes you on at least three random detours called relays. Your request could go from New York to South Africa, from South Africa to Hong Kong and from Hong Kong to New Jersey.
The Silk Road, a notorious online marketplace operating on the dark web, has become synonymous with illegal activities and underground trading. Launched in 2011 by Ross Ulbricht, operating under the pseudonym “Dread Pirate Roberts,” the Silk Road quickly gained notoriety for its facilitation of illegal drug sales, hacking services, counterfeit currency, and even hitman-for-hire schemes.
Silk Road Arrest Shines Light on ‘Dark Web’
What is the Dark Web?
The dark web refers to a part of the internet that is intentionally hidden from conventional search engines and requires specific software, such as Tor, to access. This anonymity attracts users seeking privacy, but it also provides an ideal environment for illicit activities.
The Birth of the Silk Road
The Silk Road was created as an encrypted online marketplace where users could anonymously trade goods and services using Bitcoin, a decentralized digital currency. Ulbricht envisioned the platform as a libertarian experiment, aiming to empower individuals and bypass government regulations. However, the Silk Road quickly became infamous for its association with illegal activities.

The Rise and Fall
The current fastest-growing market seems to be Evolution, which uses the inbuilt multiple-person escrow facilities of bitcoin, known as “multi-sig transactions”, whereby funds are only released from a buyer to a seller once a third party has signed off the deal. Building an engaging story around Silk Road was no small feat — particularly given the need to represent the complexities of technologies like Tor and bitcoin to a general moviegoing audience – and “we were constantly trying to recalibrate,” Russell recalled. “I knew the odds of him being willing to speak with me were very low, but I figured it was incumbent upon me to take a shot at it anyway,” he told Cybercrime Magazine in the runup to the release of the film, which is available now on streaming services.

As word spread about the Silk Road, it attracted a significant user base, estimated to have generated millions of dollars in revenue. The marketplace offered a range of drugs, fake passports, hacking tools, and other illicit goods. Law enforcement agencies around the globe eventually cracked down on the Silk Road, leading to Ulbricht’s arrest in 2013 and the closure of the original site.
But before he had a chance to visit, Ross Ulbricht was arrested by the FBI in the fall of 2013. This followed a lengthy investigation by the FBI and other agencies, including the IRS, DEA, and Department of Homeland Security.

Frequently Asked Questions (FAQs)
- In line with this, cybercrime and the issue of privacy coins are on the agenda of regulatory authorities around the globe.
- People who want to do illegal things on the Internet, such as purchase drugs through Silk Road, use Tor so that their online activity is more difficult to track.
- Recent years have witnessed the trend of studying opioid use disorders using anonymous marketplaces and forums data [5,8,10] and public social media data (eg, Twitter and Instagram) [11-14].
- The site’s alleged operator made critical missteps that allowed agents to locate the website and link him to it, court papers show.
-
Is the Silk Road still operational?
No, the original Silk Road was shut down in 2013. However, similar marketplaces have emerged since then, attempting to fill the void.
And so he went looking for leads in meetings like this, which were mostly yawners—until now. In August 2017, in a hard fork coin split, Bitcoin split into two cryptocurrencies, traditional Bitcoin and Bitcoin Cash (“BCH”). When this split occurred, any Bitcoin address that had a Bitcoin balance (as ZHONG’s addresses did) now had the exact same balance on both the Bitcoin blockchain and on the Bitcoin Cash blockchain.

Ross Ulbricht, also known as Dread Pirate Roberts, was found guilty on various charges, including money laundering, computer hacking, and conspiracy to commit drug trafficking. He was sentenced to life in prison without the possibility of parole.

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). To identify forum posts related to opioid commodity promotion and review, our methodology was designed to filter forum posts with opioid keywords and then use a classifier to the posts with the topics of interest.
Why is the dark web attractive for illegal activities?
The dark web offers users anonymity, making it difficult for law enforcement agencies to track down criminals. Additionally, cryptocurrencies like Bitcoin provide a decentralized and untraceable payment method, further facilitating illicit transactions.
Owing to the anonymity of the underground marketplaces and forums, there exists no ground truth to link users with their IDs. We trained the semantic comparison model using the traces of Reddit as the benign corpora and the traces of the anonymous marketplaces/forums as the underground corpora. Thus, we identified 58 opioid jargon used in the anonymous marketplaces and forums (Table 2). Combining opioid jargon with known opioid product names [25-27], we generated an opioid keyword data set consisting of 311 opioid keywords with 13 categories. We manually validated all keywords and the corresponding categories to guarantee their correctness.
-
Are all activities on the dark web illegal?
No, not all activities on the dark web are illegal. While it is notorious for hosting illegal marketplaces like the Silk Road, the dark web also serves as a platform for whistleblowers, activists, journalists, and individuals who require enhanced privacy.
In Conclusion
The Silk Road’s existence exemplified the power and challenges associated with the dark web. While it provided individuals with a platform for anonymous trading, it also facilitated a vast array of illegal activities. The ultimate demise of the Silk Road highlights the efforts made by law enforcement agencies worldwide to combat such illicit marketplaces on the dark web.
