Cheaper than you thought? A dive into the darkweb market of cyber-crime products

The darkweb is nowadays considered a very popular place to sell and buy illegal cyber-crime related content. From botnet services and malware, to user data such as credit card information and pass-words, darkweb marketplaces offer ease of use, product variety, and most importantly effective anonymity to both buyers and ven-dors. In this paper, we crawl 8 popular darkweb marketplaces and perform a comprehensive quantitative analysis with a focus on cyber-crime related products. Moreover, we report some prelimi-nary findings when examining the same marketplaces through their I2P mirrors. Our results suggest that overall there is a multitude of products that fall into the cyber-crime category, with products under the Fraud category dominating the market, and that the av-erage cyber-crime products' price is relatively low. Furthermore, we explore how the vendors of this specific product group are dis-tributed across platforms, utilizing harvested information such as usernames and PGP keys, and investigate how their reputation scores affect their operation.
