Written by Tomas Meskauskas on
What kind of program is Nematoda?
In the course of our inspection, we came across the finding that Nematoda is a dubious application distributed via a malicious installer. Once added, Nematoda enables the "Managed by your organization" feature. Also, this extension can read and change various data and manage other extensions (and themes) within the affected browser.
Nematoda in detail
The presence of Nematoda and its actions, particularly the activation of the "Managed by your organization" feature, indicates an attempt to exert control over the affected browser. Nematoda can enable this feature in Chrome and Edge browsers.
Enabling the "Managed by your organization" feature with an application like Nematoda poses various threats to the user's browsing environment. This feature grants Nematoda extensive control over browser settings, leading to unauthorized modifications, potential privacy breaches, unwanted extension and theme management, security vulnerabilities, and a loss of user control.
Nematoda's ability to read and alter data on all websites presents significant risks, potentially leading to various problems for users. This extensive access allows the extension to compromise sensitive information, such as login credentials and personal details, during online activities.
Users may become vulnerable to identity theft, unauthorized access to accounts, and other malicious activities. Nematoda's indiscriminate data manipulation capability raises concerns about the integrity of online transactions, communication, and overall privacy.
Nematoda's capacity to manage themes and extensions within the affected browser introduces additional risks and potential disruptions. This capability allows the extension to modify the browser's appearance and functionality by adding or removing themes and extensions. Users may experience unwanted changes to their browsing environment, encounter unfamiliar extensions, or even face compatibility issues with existing ones.
Moreover, the installer distributing Nematoda includes other unwanted apps, like the Chromstera browser, alongside potential additions such as browser hijackers, adware, and similar programs. Consequently, users should remove not only Nematoda but also any additional apps that might be installed (or added) with it.
