Naturethemetab.com

In the ongoing efforts to secure online environments, cybersecurity researchers have identified a dubious search engine, Naturethemetab.com. This discovery was made during an investigation of the Nature Theme Tab browser extension. Promoted as a tool for displaying nature-themed wallpapers, Nature Theme Tab has been found to alter browser settings, thus endorsing Naturethemetab.com. Consequently, this extension is classified as a browser hijacker, and it may also promote other fake search engines.

Characteristics of Browser Hijackers

Browser hijackers typically modify key browser settings, including the default search engine, homepage, and new tab pages. These alterations cause users to be redirected to the promoted webpage whenever a search query is entered into the URL bar or a new tab/window is opened. The Nature Theme Tab extension has been confirmed to promote Naturethemetab.com, exemplifying such behavior. Additionally, browser-hijacking software may ensure persistence by restricting access to removal-related settings or reversing user-made changes.

Redirect Behavior and Data Collection

Illegitimate search engines like Naturethemetab.com often fail to provide genuine search results, leading users instead to legitimate internet search websites. During the analysis, Naturethemetab.com redirected to the Yandex search engine, though this destination might vary based on factors like user geolocation. Furthermore, browser hijackers typically monitor users' browsing activities, potentially collecting data such as browsing and search histories, browser cookies, usernames, passwords, personally identifiable information, and financial details. This data can then be monetized through sale to third parties.

Risks and Consequences

The presence of browser-hijacking software like Nature Theme Tab on devices can lead to severe repercussions, including system infections, significant privacy issues, financial losses, and even identity theft. Such risks underscore the importance of addressing and mitigating these threats promptly.

Distribution Methods

Researchers identified the Nature Theme Tab extension on an official download webpage. However, browser hijackers are often promoted through scam sites employing scare tactics or other social engineering techniques. Users commonly encounter these malicious pages through redirects generated by intrusive ads, rogue advertising networks, spam browser notifications, mistyped URLs, and pre-installed adware.

Bundling and Intrusive Advertisements
Another prevalent distribution method is 'bundling,' where legitimate program installers are packaged with unwanted or malicious supplements, such as browser hijackers. The risk of bundled content infiltrating systems is heightened by downloading from untrustworthy sources (e.g., freeware sites, Peer-to-Peer sharing networks) and by careless installation practices (e.g., ignoring terms, skipping steps, using 'Quick/Easy/Express' settings). Additionally, intrusive advertisements can spread browser-hijacking software, with some ads executing scripts to download/install software without user consent.

Recommendations for Users

To prevent the installation of malicious software, it is crucial to research software prior to downloading or purchasing. Users are advised to download only from official and verified sources, carefully read terms and conditions, scrutinize available options, utilize 'Custom/Advanced' settings, and opt out of unnecessary additions. Moreover, exercising caution while browsing is essential, as fraudulent and malicious online content often appears legitimate. For instance, seemingly harmless ads may redirect users to questionable sites promoting scams, pornography, or gambling.

Conclusion

The discovery of Naturethemetab.com and its associated browser hijacker, Nature Theme Tab, highlights the ongoing threats posed by malicious software. By understanding the characteristics, risks, distribution methods, and preventive measures, users can better protect themselves from such threats and maintain a secure online environment.
