KittyTab Browser Extension

During an investigation into suspicious websites, researchers stumbled upon the KittyTab browser extension. This seemingly innocuous software is marketed as a utility designed to adorn your Web browser with feline-themed wallpapers. However, upon closer examination, it became apparent that KittyTab is not what it claims to be; instead, it functions as yet another intrusive browser hijacker. This extension carries out unauthorized changes to your browser's settings, ultimately leading to the promotion of the deceptive kittytab.com search engine through frequent redirects.

The KittyTab Browser Hijacker Makes Unwanted Changes to Users' Browsers

Browser-hijacking software is notorious for its ability to tamper with various browser settings, including the default search engine, homepage and settings for new tabs and windows. This meddling results in a frustrating outcome: any Web searches conducted through the browser's URL bar or when opening new tabs and windows lead to automatic redirects to a designated, often unsolicited website.

KittyTab, like many other browser hijackers, follows a similar pattern in its mode of operation. When this extension is installed, users frequently find themselves redirected to the kittytab.com webpage. This website often serves as a front for a fake search engine, which, in this case, redirects users to Bing. It's worth noting that redirection destinations may vary based on user geolocation or other factors.

A common tactic employed by browser-hijacking software is the implementation of mechanisms that ensure its persistence within the affected browser. This persistence complicates the removal process and can thwart users' efforts to regain control of their browsers.

Additionally, software falling into this category often includes data-tracking capabilities, and KittyTab is no exception. This means it may collect a wide range of user information, including visited URLs, viewed pages, search queries, internet cookies, login credentials, personally identifiable information and financial data. Once collected, this information can be monetized by selling it to third parties, potentially raising privacy and security concerns for users.

PUPs (Potentially Unwanted Programs) and Browser Hijackers are Rarely Installed Intentionally

PUPs and browser hijackers are known for employing a variety of shady distribution tactics to infiltrate users' systems and browsers. These tactics are often deceptive and can lead to unwanted software installations. Here are some of the common distribution methods abused by PUPs and browser hijackers:

• Software Bundling: PUPs and browser hijackers are frequently bundled with legitimate software downloads. Users may unknowingly install these unwanted programs when they install legitimate software from unreliable sources or neglect to review installation options carefully.
•  Deceptive Advertisements and Pop-ups: Shady websites and pop-up advertisements can trick users into clicking on deceptive download buttons, claiming to offer useful software or updates. Instead, users end up installing unwanted programs.
•  Fake Updates: PUPs and browser hijackers can be disguised as software updates, such as Adobe Flash Player or Java updates. Users may be prompted to install these updates when visiting compromised websites, which can lead to unwanted software installations.
•  Spam Email Attachments: Fraudulent email attachments may contain PUPs or browser hijackers. Users who open these attachments may inadvertently install the unwanted software on their devices.
•  Freeware and Shareware: Some PUPs are distributed through free or shareware applications. Users who download and install these free applications may not realize that they are also installing additional unwanted programs.
•  Peer-to-Peer (P2P) File Sharing: P2P file-sharing networks can be a source of PUPs and browser hijackers. Users who download files from these networks may unknowingly acquire unwanted software along with the desired content.
•  Social Engineering: Some distribution tactics rely on social engineering, using persuasive or coercive methods to trick PC users into taking actions that lead to the installation of unwanted programs.

To protect against PUPs and browser hijackers, it's imperative to exercise caution when downloading and installing software, avoid visiting suspicious websites, use reputable security software, and keep operating systems and browsers up to date to patch known vulnerabilities. Additionally, regularly reviewing and managing browser extensions and add-ons can help prevent unwanted software from taking control of your browser.
