These scripts record your keystrokes, mouse movements, and scrolling behaviour, along with the entire contents of the pages you visit, and send them to third-party servers. The Guardian, Reuters, Samsung, Al-Jazeera, VK, Adobe, Microsoft, and WordPress are among the most popular sites using the technique. The researchers looked at some of the leading companies, including FullStory, SessionCam, Clicktale, Smartlook, UserReplay, Hotjar, and Yandex.
