Cyber threat intelligence (CTI) is vital for enabling effective cybersecurity decisions by providing timely, relevant, and actionable information about emerging threats. Monitoring the dark web to generate CTI is one of the upcoming trends in cybersecurity. As a result, developing CTI capabilities with the dark web investigation is a significant focus for cybersecurity companies like Deepwatch, DarkOwl, SixGill, ThreatConnect, CyLance, ZeroFox, and many others. In addition, the dark web marketplace (DWM) monitoring tools are of much interest to law enforcement agencies (LEAs). The fact that darknet market participants operate anonymously and online transactions are pseudo-anonymous makes it challenging to identify and investigate them. Therefore, keeping up with the DWMs poses significant challenges for LEAs today. Nevertheless, the offerings on the DWM give insights into the dark web economy to LEAs. The present work is one such attempt to describe and analyze dark web market data collected for CTI using a dark web crawler. After processing and labeling, authors have 53 DWMs with their product listings and pricing.

Dalvi, Ashwini, Ankamwar, Lukesh, Sargar, Omkar, Kazi, Faruk, Bhirud, S.G..  2021.  From Hidden Wiki 2020 to Hidden Wiki 2021: What Dark Web Researchers Comprehend with Tor Directory Services? 2021 5th International Conference on Information Systems and Computer Networks (ISCON). :1—4.
The dark web searching mechanism is unlike surface web searching. On one popular dark web, Tor dark web, the search is often directed by directory like services such as Hidden Wiki. The numerous dark web data collection mechanisms are discussed and implemented via crawling. The dark web crawler assumes seed link, i.e. hidden service from where the crawling begins. One such popular Tor directory service is Hidden Wiki. Most of the hidden services listed on the Hidden Wiki 2020 page became unreachable with the recent upgrade in the Tor version. The Hidden Wiki 2021 page has a limited listing of services compared to the Hidden Wiki 2020 page. This motivated authors of the present work to establish the role of Hidden wiki service in dark web research and proposed the hypothesis that the dark web could be reached better through customized harvested links than Hidden Wiki-like service. The work collects unique hidden services/ onion links using the opensource crawler TorBot and runs similarity analysis on collected pages to map to corresponding categories.
