This report profiles Kilos, a November 2019 dark web search engine that appears to have evolved from Grams; it details Kilos' larger indexing of marketplaces and forums (hundreds of thousands of posts, listings, vendors, and reviews), advanced search and filtering, novel CAPTCHA, a built-in Bitcoin mixer named Krumble, and community features such as live chat and direct admin interaction, and explains how these features could expand access to illicit goods and benefit both criminals and researchers.
