What Does The Nautica Browser Hijacker Do?
Our researchers recently uncovered the Nautica browser extension, which is a form of malicious software known as a browser hijacker. This type of program alters browser settings, causes redirects, and monitors user activity while browsing the web.
Browser hijackers are notorious for promoting fake search engines by making them the default URL for browsers, as well as their homepage and new tab/window. As a result, when users open a new tab or search via the URL bar they are taken to the promoted website instead of their desired destination.
When tested, Nautica was found to redirect users to Bing's legitimate search engine (bing.com). However, it is possible that this extension could lead people to other fake or genuine search engines depending on various factors such as user geolocation.
Nautica also has techniques in place to make sure it remains persistent on users' systems and cannot be easily removed. Additionally, it has data-tracking capabilities which allow it to collect information such as visited URLs, viewed webpages, searched queries, bookmarks, usernames/passwords, personal details and financial information. This data can then be sold to third-parties for profit.
What settings will browser hijackers commonly change in your browser?
Browser hijackers commonly change the default URL, homepage, and new tab/window settings in a browser. They may also alter other settings such as search engine preferences, security settings, and privacy settings. Those changes usually happen without proper disclosure and explicit user consent, which is what makes browser hijackers problematic.
How can you protect your browser from browser hijackers similar to Nautica?
Browser hijackers commonly change the default URL, homepage, and new tab/window settings in a browser. They may also alter other settings such as search engine preferences, security settings, and privacy settings.
