Cat Tab HD Browser Extension

The Cat Tab HD is a browser extension that allows users to showcase cat-themed background images on their Web browsers, adding an element of enjoyment to their online experience. However, caution is advised as security researchers have discovered that the Cat Tab HD goes beyond its intended functionality. Analysis reveals that the extension has the potential for browser hijacking, altering browser settings upon installation to endorse thecattab.com, a fraudulent search engine, through redirects. In addition to this concerning behavior, there is a likelihood that the Cat Tab HD may possess data-tracking capabilities, raising privacy and security concerns for users.

The Cat Tab HD Takes Over Essential Browser Settings

The Cat Tab HD goes beyond its intended purpose by reassigning default settings in Web browsers, specifically altering default search engines, homepages and new tab pages to redirect users to thecattab.com website. Consequently, users are consistently directed to this page when performing searches or opening new tabs.

It's crucial to note that browser-hijacking software, like the Cat Tab HD, often employs techniques to ensure persistence. This includes undoing user-made changes and restricting access to removal-related settings, complicating the removal process and hindering browser recovery.

In typical scenarios involving fake search engines, they are unable to generate authentic search results and usually redirect users to legitimate search sites. Thecattab.com follows this pattern by redirecting users to the Google search engine. However, it's important to recognize that the redirection destination may not always be the same, based on factors such as user geolocation.

Moreover, the Cat Tab HD may possess data-tracking capabilities, a common trait among browser hijackers. The information collected can include visited URLs, viewed Web pages, search queries, Internet cookies, usernames/passwords, personally identifiable details and financial data. This data could be exploited for profit through sale to third parties or other unauthorized uses, raising significant privacy and security concerns for users.

Browser Hijackers could Use Dubious Distribution Methods to Hide Their Installations

Browser hijackers could employ dubious distribution methods to conceal their installations and increase the likelihood of getting installed on users' systems without detection. Some common tactics used by these malicious entities include:

• Bundled Software: Browser hijackers may be bundled with seemingly legitimate software or free applications that users download from the Internet. Users might overlook or unintentionally accept additional components during the installation process, allowing the hijacker to be installed alongside the desired software.
•  Deceptive Websites: Rogue websites may use misleading tactics to trick users into installing browser hijackers. This can involve fake pop-up messages claiming that certain software or updates are required, leading users to initiate the installation of the hijacker unknowingly.
•  Malvertising: Browser hijackers could be distributed through unsafe advertisements (malvertising) on legitimate websites. Unsuspecting users may click on these advertisements, thinking they are legitimate, and inadvertently trigger the download and installation of the hijacker.
•  Email Attachments and Links: Some browser hijackers may be spread via email attachments or links in phishing emails. Users who open attachments or click on links may unknowingly download and install the hijacker on their systems.
•  Social Engineering: Fraud-related actors may use social engineering techniques, such as fake notifications or alerts, to manipulate users into installing browser hijackers. This could involve convincing users that they need to update their software or plugins, leading to the inadvertent installation of the hijacker.
•  Fake Browser Extensions: Dubious browser extensions masquerading as legitimate or desirable add-ons may be offered for download. Users who install these extensions may unknowingly introduce a browser hijacker into their system.

To protect against these dubious distribution methods, users should exercise caution when downloading software, be wary of clicking on suspicious links or pop-ups, regularly update their software and browsers, use reputable security software, and scrutinize email attachments from unknown or unexpected sources. Additionally, being cautious about granting unnecessary permissions during software installations can help prevent the inadvertent installation of browser hijackers.
