Mycool Search Browser Extension

During an analysis of suspicious websites, researchers stumbled upon the Mycool search browser extension. Upon closer examination, they identified it as a browser hijacker due to its typical characteristics. The Mycool search extension is found to be making undesired alterations to critical browser settings, with the primary intent of endorsing the search.mycooltab.com fake search engine through redirects.

The Mycool Search Browser Hijacker Takes Users to Unwanted Destinations

Browser-hijacking software operates by modifying key browser settings, such as default search engines, homepages, and new tab pages, to promote specific websites. Consequently, whenever users open new tabs or initiate search queries through the URL bar, they are redirected to the endorsed webpage. The Mycool search extension employs this technique to promote search.mycooltab.com.

Typically, fake search engines lack the capability to generate search results, leading users to legitimate Internet search websites. In the case of search.mycooltab.com, it directs users to the Bing search engine; however, variations may occur based on factors like user geolocation. Additionally, browser hijackers often employ persistence-ensuring mechanisms, complicating their removal and thwarting users' attempts to restore their browsers to default settings.

Moreover, it is likely that Mycool search incorporates data-tracking functionalities, a common feature in browser-hijacking software. This functionality enables the collection of targeted information, including visited URLs, viewed pages, search queries, Internet cookies, login credentials, personally identifiable details, financial data, and more. Subsequently, this gathered information may be shared with or sold to third parties.

Browser Hijackers Often Attempt to Hide Their Installation from Users

Browser hijackers frequently employ various tactics to conceal their installation from users, making it challenging for individuals to detect and remove them. Here are some common strategies used by browser hijackers to hide their presence:

  • Bundling with Freeware: Browser hijackers often come bundled with seemingly legitimate freeware or shareware applications. Users may inadvertently install the hijacker when they install the desired software without paying close attention to the installation process.
  •  Misleading Installation Techniques: Some browser hijackers use deceptive installation techniques, such as hiding their presence in the 'Custom' or 'Advanced' installation options. Users who choose the default or express installation may overlook the additional components being installed.
  •  Aggressive Click-through Installation: Browser hijackers may employ aggressive click-through installation, where they rapidly advance through installation steps, making it difficult for users to review and deselect unwanted components.
  •  Masquerading as Legitimate Software: Some browser hijackers disguise themselves as legitimate software updates or security tools. Users may be misled into thinking they are installing a beneficial update, only to discover later that a browser hijacker has been installed.

To protect against browser hijackers, users should be cautious when downloading and installing software, opting for custom installations, keeping their software up-to-date, and using reputable security software to scan and safeguard their systems. Regularly reviewing installed browser extensions and add-ons is also advisable to identify and remove any potentially unwanted programs.
