What is PumaConcolor?
During the examination of a dubious installer obtained from an unreliable website, the PumaConcolor browser extension was encountered. The inquiry unveiled that this extension possesses suspicious characteristics. PumaConcolor has the ability to activate the "Managed by your organization" feature within the Chrome browser, gather various data, and manipulate specific browser elements.
PumaConcolor in detail
If granted permission, PumaConcolor can gain access to and make changes to data across all websites, as well as manage apps, extensions, and themes within the Chrome browser. This implies that PumaConcolor could access information such as login credentials, credit card details, and other sensitive information. This presents a significant privacy issue, as the developers of PumaConcolor may misuse the mentioned data.
The PumaConcolor's capability to handle apps, extensions, and themes means it can change how the browser works. This might lead to unwanted changes in the browsing environment, like adding extra (potentially malicious) extensions or tweaking the browser's settings.
It is crucial to review and monitor the permissions given to browser extensions carefully. If there are extensions that are not actively used or trusted, especially those with overly broad permissions like PumaConcolor, they should be removed from browsers.
Additionally, the installer used to distribute PumaConcolor contains additional unwanted software, such as the Chromstera web browser. PumaConcolor might also be bundled with other questionable applications, like adware and browser hijackers.
It is important to remember that cybercriminals can employ unreliable installers to distribute Trojans, ransomware, cryptocurrency miners, and other forms of malware. Hence, it is highly advisable to exercise vigilance and refrain from using installers sourced from questionable websites and other untrustworthy origins.

How did PumaConcolor on my computer?
Users often end up having undesired apps like PumaConcolor on their browsers accidentally. One common scenario is through bundled software downloads, where programs (mostly free ones) include extra software or browser extensions that users unknowingly accept during the installation.
Misleading websites can also use tricks like fake download buttons, bogus software updates, or misleading ads to deceive users into getting unwanted apps.

To keep unwanted applications out of their web browsers, users should be cautious when downloading and installing software, steer clear of suspicious links and ads, keep their software and operating systems up-to-date, and use reliable antivirus and anti-malware tools to detect and remove potential threats.
