Url Hijacking

URL hijacking refers to techniques used to redirect or seize control of web addresses, often diverting users or search visibility away from their intended destination.

Definition

URL hijacking is a form of cyber manipulation where an attacker intercepts or alters a URL so that users are sent to an unintended, often malicious, destination instead of the legitimate one. This can include black-hat SEO tactics that replace a site’s search result listing, redirects based on typos or spoofed domains, and other redirect exploits that undermine trust and traffic. In some contexts, it also involves leveraging display URLs in paid search to usurp a brand’s visibility. URL hijacking can expose users to phishing, malware, or data theft while damaging the reputation and performance of the original site.
