PDF Converty New Tab Browser Extension

An analysis carried out by infosec specialists on the PDF Converty New Tab browser extension has definitively established that the application functions as a browser hijacker. Browser hijackers are generally considered to be untrustworthy software programs with the intention of promoting deceptive or fake search engines. In this specific scenario, the impact of the PDF Converty New Tab extension involves configuring users' Web browsers to initiate involuntary redirects to the Web address feed.promisearch.com. To achieve this objective, the PDF Converty New Tab application utilizes a mechanism to modify the configuration settings within the user's Web browser, thereby enabling these unwarranted redirections to occur.

Browser Hijackers Like the PDF Converty New Tab Carry Out Unauthorized Modifications

The PDF Converty New Tab extension is initially presented as a tool designed to facilitate the conversion of various file formats into PDFs. However, its actual functionality involves more than that – it manipulates the settings within web browsers, including making changes to the default search engine, the new tab page, and the homepage. These alterations effectively make the feed.promisearch.com page as the users' primary search engine.

Following a comprehensive investigation, researchers have confirmed that feed.promisearch.com does not provide distinct or unique search results. Instead, users are redirected to search.yahoo.com, a reputable search engine owned by Yahoo. It's important to emphasize that relying on fake or dubious search engines could lead users to engage with suspicious and unreliable online content.

Furthermore, browser hijackers often inundate users with a barrage of unwanted advertisements, and intrusive pop-ups, and in some instances, even expose them to potentially hazardous websites. These actions substantially elevate the risk of encountering malware infections and compromise user privacy by capturing personal information. Such practices not only disrupt the user experience but also pose serious security and privacy threats.

PUPs (Potentially Unwanted Programs) and Browser Hijackers Mask Their Installations via Shady Distribution Tactics

PUPs and browser hijackers employ a range of shady distribution tactics to mask their installations and infiltrate users' systems without their explicit consent. These tactics are often designed to deceive users and make it difficult for them to recognize that they are installing unwanted software. Here's an explanation of how PUPs and browser hijackers use these tactics:

• Bundling with Legitimate Software: PUPs and browser hijackers are often bundled with seemingly legitimate software downloads. When users download and install a desired program, these unwanted applications piggyback along with the installation process. The bundled software might be disclosed in fine print or hidden within the installation options, leading users to install it inadvertently.
• Deceptive Installation Wizards: Some PUPs and browser hijackers utilize installation wizards that purposefully confuse users. They may present options that lead users to believe they are making necessary choices, while in reality, these choices result in the installation of additional unwanted software.
• Fake Updates and Downloads: Some PUPs and browser hijackers mimic legitimate software updates or downloads. Users might be prompted to install what seems like an important update, but in reality, they end up installing unwanted software instead.
• Clickbait and Fake Ads: Fraudulent advertisements and pop-ups might present enticing offers, prizes, or urgent alerts that encourage users to click and install software. These advertisements can lead users to download and install PUPs or browser hijackers without realizing it.
• Impersonation of Legitimate Software: PUPs and browser hijackers often imitate the appearance and functionality of well-known and trusted software. Users might mistake them for legitimate programs and willingly install them.
• Use of Peer-to-Peer Networks: PUPs and browser hijackers might be distributed through peer-to-peer networks, file-sharing platforms or torrent downloads. Users seeking to download software from these sources may unknowingly download bundled unwanted programs as well.
• Phishing and Social Engineering: Some distribution tactics involve phishing emails or websites that fool users into thinking they need to download specific software to fix issues, enhance security, or gain access to content. These tactics exploit users' trust to encourage installation.

To protect against these tactics, users should be cautious while downloading and installing software, especially from unverified sources. It's crucial to read installation prompts carefully, choose custom installation options when available, and keep their security software updated to detect and prevent the installation of PUPs and browser hijackers.
