These sites are capturing everything you type, mouse over, and click on. You know, sort of like a\u00a0keylogger<\/a><\/u>. For performance diagnostics, some of it makes sense: When you run a website that can have hundreds of thousands of pages, you need to learn what people are doing on them and if any pages are broken or not working as intended.<\/p>\n Problems arise, however, because the software is capable of tracking a great deal of information that isn\u2019t necessarily useful for website developers, and because third parties have access to that information. A group of researchers from Princeton University\u00a0reported on the phenomenon<\/a>, saying: \u201cCollection of page content by third-party replay scripts may cause sensitive information such as medical conditions, credit card details and other personal information displayed on a page to leak to the third-party as part of the recording. This may expose users to identity theft, online scams, and other unwanted behavior<\/i>.\u201d<\/em><\/p>\n As the researchers also pointed out, this sort of playback software is \u201clike somebody looking over your shoulder,\u201d<\/em> while you\u2019re online.\u00a0Watch the video below to learn more about how it works.<\/p>\n![\"\"](\"https:\/\/media.kasperskydaily.com\/wp-content\/uploads\/sites\/92\/2017\/11\/24062603\/website-tracking-1024x672.jpg\"){kind=tracking}
