ZenFocusZone Browser Extension
Our research team came across the ZenFocusZone browser extension while examining suspicious websites. This software modifies browser settings to endorse the zenfocuszone.com fake search engine, resulting in its classification as a browser hijacker.
Browser-hijacking tools set promoted website addresses as default search engines, homepages, and new tab/window URLs. Consequently, opening new tabs/windows and entering search queries into the URL bar lead to redirects to the advocated webpage. In the case of ZenFocusZone, this is zenfocuszone.com.
It's essential to note that browser hijackers often employ persistence-ensuring mechanisms, preventing access to removal-related settings or reversing user-made changes to hinder browser restoration.
Fake search engines typically lack the ability to provide authentic search results, redirecting instead to legitimate internet search platforms. Zenfocuszone.com directs users to the Bing search engine (bing.com). It's worth mentioning that the destination page could vary based on factors like user geolocation influencing redirects.
Software falling into this category often includes data-tracking features, a characteristic that may apply to ZenFocusZone. The data of interest may encompass visited URLs, viewed webpages, entered search queries, internet cookies, login credentials, personally identifiable details, financial information, and more. Collected data can be monetized by selling it to third parties.
