Qwik Ant Browser Extension

During their investigation of suspicious websites, infosec researchers came across the Qwik Ant browser extension. This extension was initially marketed as a productivity tool designed to provide users with convenient access to various popular online platforms and services. However, upon activation and installation on a user's system, Qwik Ant exhibits a rather deceptive behavior. It makes unwarranted alterations to the user's Web browser settings with the sole intent of promoting the search.qwikant.com search engine through a series of redirects. This behavior is characteristic of a browser hijacker.

The Qwik Ant Browser Hijacker Performs Intrusive Changes

The Qwik Ant, once installed as a browser extension, disrupts the user's browser experience by making unwanted alterations to several key settings. This includes the modification of the browser's homepage, new tab pages and default search engine. As a result, users with this extension activated on their browsers encounter a series of redirects when conducting Web searches via the URL bar and opening new browser tabs, all leading to the search.qwikant.com Web page.

It is essential to note that many fake or illegitimate search engines, like search.qwikant.com, lack the capability to generate their own search results. Instead, they often redirect users to well-established and genuine Internet search engines such as Google, Bing or Yahoo. However, the search.qwikant.com Web page leads to a nonfunctional page. It remains unclear whether this nonfunctional page was intended to be the final landing page or just a component within a more extensive redirection chain.

It's worth emphasizing that the behavior of search.qwikant.com, or the final destination of such redirections, can vary based on factors like the geographical location of the user. This variability in redirection highlights the elusive nature of such browser-hijacking tactics.

Additionally, it's important to understand that browser-hijacking software, including the Qwik Ant, often employs techniques to ensure its persistence on the user's system, making its removal and the restoration of browser settings a challenging task. This persistence may include resisting standard uninstallation methods and taking steps to hinder the recovery of the browser's original settings.

Furthermore, browser hijackers often incorporate data-tracking functionalities into their operations, which may also apply to the Qwik Ant. This means that sensitive user data, including information related to visited URLs, viewed webpages, search queries, Internet cookies, usernames and passwords, personally identifiable details, and even financial information, could be collected without consent. This harvested data can then be exploited for profit through various means, such as selling it to third parties or employing it for unsafe purposes.

Users Often Do Not Realize They Are Installing PUPs (Potentially Unwanted Programs) or Browser Hijackers

PUPs and Browser Hijackers frequently employ shady distribution tactics to install themselves on users' systems without drawing attention. These tactics include:

• Bundling: One of the most common methods is bundling with legitimate software. PUPs and Browser Hijackers are included as optional or hidden components within the installation packages of legitimate applications. Users often rush through the installation process and may overlook or unintentionally accept the bundled software.
•  Deceptive Installers: Some PUPs use deceptive installation wizards that manipulate users into installing unwanted software. This can involve pre-selecting checkboxes for additional software or using misleading wording to confuse users into accepting the installation.
•  Fake Updates: PUPs may masquerade as legitimate software updates, such as Adobe Flash Player or Java updates. Users are tricked into downloading and installing these fake updates, which are, in reality, malicious programs.
•  Email Attachments and Links: Phishing emails containing attachments or links can lead users to download and install PUPs. These emails are often designed to appear as if they originate from trustworthy sources, luring users into downloading and executing unsafe software.
•  Social Engineering: Some PUPs employ social engineering tactics, such as displaying fake security warnings or pop-up messages that claim the user's system is infected or requires an urgent update. Users are coerced into taking action that installs the unwanted software.
•  Malvertising: Fraudulent advertising (malvertising) is another common distribution method. Malvertisements appear on legitimate websites and lead users to sites that automatically download PUPs or Browser Hijackers onto their systems.
•  File-Sharing Platforms: PUPs can be distributed through file-sharing platforms and torrent websites. Users looking to download files or software from these sources may unknowingly acquire unwanted programs alongside their intended downloads.

These shady distribution tactics are designed to deceive and manipulate users into installing PUPs or Browser Hijackers, often without their knowledge or explicit consent. This not only compromises the user's system but can also have privacy and security implications, as these programs may collect and misuse sensitive data. Therefore, it's essential for users to exercise caution, use reputable sources for software downloads, and maintain up-to-date security measures to prevent falling victim to these dubious distribution practices.
