Summary
Users should not engage with advertisements delivered by such dubious sources or risk being redirected to suspicious or outright unsafe destinations - hoax websites, domains spreading more PUPs, phishing pages, etc. Typically, browser hijackers drive artificial traffic towards a fake search engine that would otherwise be completely ignored by the users. Users may be shown results from a legitimate engine (Yahoo, Bing, Google) or see their searches taken to a dubious one. Another serious red flag exhibited by PUPs is their ability to spy on the users browsing activities. The information of interest may include each visited website, clicked links, and initiated search, as well as the devices IP address, geolocation, browser type, ISP and more.
