Browser hijacking is a form of malware. It secretly modifies your web browser settings without your knowledge. It changes your homepage, default search engine, and new tab page. It redirects your searches to malicious websites. In addition, it generates fraudulent ad revenue for criminals and can install spyware or ransomware on your device.
What Is Browser Hijacking?
A browser hijacker is malware that takes control of your web browser. It typically arrives via a bundled software download or a malicious link. Once installed, it alters your browser configuration to redirect searches, inject advertisements, and track your browsing activity. The criminal then profits from fraudulent ad clicks. Furthermore, they often sell your browsing data to third parties. Serious hijackers can also steal banking credentials and financial information.
