If we think about the web as an ocean of data, the Surface Web is no more than the slight waves that float on the top. The good performance of the classifier might support potential tools to help the authorities in the detection of these activities. We found that the combination of TF-IDF words representation with Logistic Regression classifier achieves 96.6% of 10 folds cross-validation accuracy and a macro F1 score of 93.7% when classifying a subset of illegal activities from DUTA. We also fixed the pipeline elements and identified the aspects that have a critical influence on the classification results. Using DUTA, we conducted a comparison between two well-known text representation techniques crossed by three different supervised classifiers to categorize the Tor hidden services. We built DUTA by sampling the Tor network during two months and manually labeled each address into 26 classes. In this paper, we present and make publicly available a new dataset for Darknet active domains, which we call it ”Darknet Usage Text Addresses” (DUTA).

The freedom of the Deep Web offers a safe place where people can express themselves anonymously but they also can conduct illegal activities. 5.By Mhd Wesam Al Nabki, Eduardo Fidalgo, Enrique Alegre & Ivan de Paz Department of Electrical, Systems and Automation, University of Leon, Spain & INCIBE Spanish National Cybersecurity Institute Abstract It was ProPublica's fifth Pulitzer Prize.

ProPublica was one of the first major news outlets to launch a dark web version of its site back in 2016. If you have a curious mind, you are likely to find Dig Deeper interesting. You will find a number of articles on different topics (mostly tech-related) with quite a lot of supporting evidence. It mainly discusses security topics like the safest browsers and email providers you should use.
