BegoniaSemperflorens Browser Hijacker

While investigating a malicious installer, we came across BegoniaSemperflorens and its worrisome behavior as a browser extension. These actions involved implementing the "Managed by your organization" feature within the Chrome browser, gathering various types of data, and overseeing specific aspects of the browser's functionality.

BegoniaSemperflorens possesses the capability to access and modify data on all web pages visited by users, including potentially sensitive information like login credentials, personal details, and browsing history. This presents a potential risk of mishandling or malicious use of this data, which could result in breaches of privacy.

Additionally, BegoniaSemperflorens can manipulate the appearance and functionality of the browser by managing applications, extensions, and themes. This may lead to unwanted changes that disrupt the browsing experience or expose users to potentially harmful content.

Furthermore, BegoniaSemperflorens might be designed to tamper with browser settings, inject malicious code, or introduce vulnerabilities that could leave systems susceptible to security threats, including malware and phishing attacks.

In our investigation, we also discovered that the distributor of BegoniaSemperflorens, the installation package, includes additional unwanted software components, such as the Chromstera web browser. In some instances, programs similar to BegoniaSemperflorens may be bundled with other undesirable applications like adware and browser hijackers.

Moreover, the installers responsible for disseminating these programs may hide more severe threats, such as ransomware, Trojans, cryptocurrency miners, and other forms of malicious software.

How Are Rogue Browser Extensions Distributed Online?

Rogue browser extensions are typically distributed online through various deceptive or malicious methods. These extensions may appear harmless but often engage in activities that compromise user privacy, security, or browsing experience. Here are common ways rogue browser extensions are distributed:

• Fake or Malicious Extension Stores: Cybercriminals create fake extension stores or websites that mimic legitimate sources like the Chrome Web Store or Mozilla Add-ons. Users are tricked into downloading extensions from these sites, thinking they are genuine.
• Bundled with Freeware: Rogue extensions can be bundled with free software or applications that users download from the internet. During the installation process, users may not notice that they are also agreeing to install the extension.
• Misleading Ads and Pop-ups: Malicious ads or pop-ups may prompt users to install browser extensions, often under the guise of improving browsing experience or offering free tools. Clicking on these ads may lead to the installation of rogue extensions.
• Email Phishing: Cybercriminals may send phishing emails containing links that lead to malicious extension downloads. These emails are designed to deceive users into believing they need the extension for some legitimate purpose.
• Social Engineering: Rogue extensions may spread through social engineering techniques, such as enticing users with promises of discounts, prizes, or exclusive content if they install the extension.
• File Sharing and Torrent Sites: Some users may download software or media files from file-sharing or torrent websites. Rogue extensions can be packaged with these downloads and installed without the user's knowledge.
• Malicious Links: Users may be directed to websites that initiate the installation of rogue extensions when they click on certain links. This can happen through deceptive tactics like fake "Download" or "Update" buttons.
• Drive-by Downloads: In some cases, rogue extensions may be silently downloaded and installed on a user's system when they visit compromised or malicious websites. This can occur without any user interaction.
