Though, the site would actually be controlled by the malicious hackers functioning the attack, just as it would happen after the attackers exploited the researcher’s spoofing address bar bug in the Android DuckDuckGo Privacy Browser.

Thus, unaware victims can be redirected to domains masked as numerous high-profile sites that might actually allow attackers to steal the personal details of their targets and by using phishing web pages or by leaving malware on their computers through malvertising attack ads.
