Dark Net Operation Dataset (Q6700715)

Dataset from the Dark Net Operation, an inquiry of the Brazilian Federal Police which tracked a child-pornography forum in the Tor network. With two phases, the investigation lasted from 2014 to 2016 and resulted in hundreds of search warrants and in almost 70 arrests, with 6 children rescued from abusive situations. On the on-line forum, the users exchanged child abuse media and sexual abuse experiences. The data from the online forum acquired by the Brazilian Federal Police was structured inside 67 categories, containing a total of 9,367 posts and 6,248,719 views made by 9,280 users. Inside the posts, users express their opinion and share CSEM content. The CSEM were often shared as an external link (URLs) to encrypted files containing photos and videos, but sometimes users upload CSEM directly inside their posts. The direct upload of files inside posts summarises 789 CSEM files. Every post, is associated with an identifier, user, category and the date/time when it was posted. Similarly, every view can be mapped to a user, post and the date/time when the post was viewed.
