Tropical Extension

The Tropical Extension is a piece of dubious software that came under the scrutiny of cybersecurity experts during their investigation of suspicious websites. Initially, it is a useful extension, offering users the allure of having tropical-themed browser wallpapers. However, upon closer examination by security professionals, it became evident that the Tropical Extension is, in fact, a browser hijacker.

Browser hijackers stealthily alter users' Web browser settings without their consent or knowledge. In the case of Tropical Extension, it utilizes this unauthorized access to promote a fake search engine at forcibly. This promotion occurs through a series of unwanted redirects that take users' web searches to the deceptive search engine, which can potentially expose the user to misleading or harmful content.

This surveillance encompasses a wide range of data, including the URLs visited, webpages accessed, search queries entered, information stored in Internet cookies, usernames and passwords, as well as personally identifiable information and financial data.

Browser Hijackers Rely Heavily on Dubious Techniques for Their Distribution

Potentially Unwanted Programs (PUPs) and browser hijackers often employ dubious techniques for their distribution, which can be deceptive and intrusive. These tactics are designed to trick users into installing the software without their informed consent. Here are some common methods used:

  • Bundled Software: PUPs and browser hijackers are frequently bundled with legitimate software downloads. Users may unknowingly install these unwanted programs when they download and install a seemingly harmless application. This bundling is often buried in the terms of service, and users may not notice it during the installation process.
  •  Deceptive Installers: PUPs and browser hijackers often use installers that employ deceptive techniques. For example, they may present users with multiple "Next" buttons that actually install additional unwanted software when clicked. Users might inadvertently install these programs while trying to install something else.
  •  Social Engineering: Some PUPs and browser hijackers use social engineering tactics to manipulate users. They might display alarming pop-up messages claiming that the user's system is infected with malware or that they need to update a crucial software component. Users are then asked to download and install the deceptive program as a solution.
  •  Browser Extensions: Browser hijackers are often distributed as seemingly innocent browser extensions or add-ons. Users might encounter enticing offers, such as 'improved browsing speed' or 'enhanced security,' and install these extensions without realizing that they will take control of their browser settings.
  •  Malvertising: Malicious advertising, known as malvertising, can be used to deliver PUPs and browser hijackers. Cybercriminals may place fraudulent advertisements on legitimate websites, and clicking on these ads can trigger the download and installation of unwanted software.
  •  Phishing Emails: PUP distributors may send phishing emails that contain attachments or links to fake websites. These emails are meant to trick users into downloading and installing unsafe software by posing as trustworthy sources.
  •  Freeware and Shareware: Some PUPs are disguised as free or trial versions of legitimate software. Users looking for cost-free alternatives to paid software may unknowingly install these unwanted programs.

To protect themselves from PUPs and browser hijackers, users should make use of caution when downloading and installing software. Always download software from official sources, read installation prompts carefully, decline bundled offers that are not needed, keep software and browsers up-to-date, and use reputable anti-malware tools to scan for and remove unwanted programs.
