ISPs install the iMarker equipment and mirror all user's traffic on it (Russian surveillance system, SORM, works the same way). Software takes time, URL and HTTP Headers from HTTP requests. Then scraper with IP 92.242.35.54 and User-Agent WebIndex follow every visited URL and analyze its content. All this information used to build a profile for user. They says that information is removed right after analysis, and software saves only result of that analysis. Their website lists that they categorize users by search queries, online shopping activity, time of visits, activity on social networks, keywords on visited pages, visited websites, social-demographic info, such as sex, age, marital status, and education level, and then they use that data to distribute users for consumers groups. Every user has some kind of pseudonymous ID with linked profile. It's also has an opt-out option http://www.imrk.net/status How many users affected? They says it's 38 million people all over Russia. Minister of Communication Nikolay Nikiforov said in 2014 there was 62 million people in Russia using Internet, 56m of them do it every day, so it's 61% of Russian Internet users. iMarker's website list Akado, Rostelecom, ER-Telecom, NetByNet, Qwerty, and TTK as ISPs that installed iMarker's equipment.
