Homepage hijacking is a malevolent practice that primarily aims to manipulate the user’s web browsing experience to gain unauthorized control over their homepage settings and redirect them to a specific webpage, typically filled with unwanted advertisements or malicious content. The purpose of this tactic is to drive traffic to predetermined sites, generating revenue for the people behind the hijacking scheme through increased ad exposure or phishing attempts.

Unscrupulous individuals or groups often use homepage hijacking to exploit naive or unsuspecting users, capitalizing on the opportunity to collect personal data or expose the victim to a barrage of unnecessary and intrusive promotions. The means through which homepage hijacking is employed can vary; however, this intrusive maneuver is most commonly achieved by executing malicious software in the background, which is often bundled with seemingly legitimate software installations or hidden in suspicious email attachments and fraudulent links.

The perpetrators prey on user trust and target a wide range of browser types, ultimately aiming to maximize their revenue and extend their reach. To guard against homepage hijacking, internet users should practice caution, vigilance, and skepticism while browsing and downloading content online.

Moreover, reputable anti-malware software is highly beneficial in detecting and neutralizing such threats, ensuring that the user’s browsing remains private, secure, and free from unwanted intrusions.

Examples of Homepage Hijacking

Homepage hijacking, also known as browser hijacking, is a form of unwanted software that modifies your web browser settings such as your default homepage, search engine, or error pages, usually without your permission. Here are three real-world examples of homepage hijacking:

CoolWebSearch: This variant of browser hijacking malware started appearing around

It was designed to redirect users to unwanted websites, particularly those containing adult content and pop-up ads. CoolWebSearch would change a user’s homepage and default search engine without their consent, generating revenue for its creators through advertising and click fraud.

Conduit Search: Conduit Search (also known as Search Protect) is another form of browser hijacker that gained prominence in the mid-2010s. It would change the user’s default search engine to Conduit Search, hijack the new tab setting, and display ads, sponsored links, and other promotional material on the search results page. It could also collect browsing data and send it to remote servers for targeted advertising. This malware typically entered users’ systems bundled with other software installations, and it often required a specific removal tool to eradicate it completely.

Babylon Toolbar: The Babylon Toolbar is a browser extension and toolbar that became notorious for its hijacking capabilities in the early 2010s. It would change users’ homepages, default search engines, and new tab settings to Babylon-related web pages. Additionally, it would display unwanted ads and sponsored search results. The toolbar was often bundled with other software installations and included options to disable these changes during installation, but many users inadvertently enabled the hijacking features. Removing Babylon Toolbar from the system usually requires a combination of uninstallation and browser settings restoration.
