Metatogger Music Collection PUA
While exploring websites offering counterfeit "cracked" software, our researchers stumbled upon an installer containing the Metatogger Music Collection PUA (potentially unwanted application). This installation package was bundled with other dubious and potentially malicious software. PUAs typically possess undesirable and harmful features.
Potentially unwanted applications are often presented as legitimate and beneficial tools. One example of this is the counterfeit anti-virus type; these applications require users to purchase activation keys for the software to function as advertised, yet even after purchase, the promised features remain inactive.
PUAs commonly incorporate data-tracking capabilities. They frequently target information such as browsing and search engine histories, internet cookies, account login credentials (usernames/passwords), personally identifiable details, credit card numbers, and more. This collected data can be monetized through sale to third parties, potentially including cybercriminals.
Unwanted applications may also feature adware capabilities. This software can display third-party graphical content (e.g., pop-ups, overlays, banners, etc.) on various interfaces. These advertisements promote deceptive and malicious content, including malware. Some ads can trigger scripts upon being clicked, leading to stealthy downloads or installations.
PUAs can also possess browser-hijacking abilities. Browser hijackers alter browser settings (e.g., homepage, default search engine, new tab/window), forcing users to visit fake search engines. These sites often fail to generate search results and instead redirect users to genuine search engines (e.g., Google, Yahoo, Bing, etc.).
Potentially unwanted applications may encompass other harmful functionalities, and they are frequently bundled with undesirable or hazardous supplements.
What Are Bundle Installers and How to Spot Them?
Bundle installers, also known as software bundlers or package installers, are tools used to distribute multiple software programs together as a single package for installation on a computer. While bundle installers can be legitimate and useful for installing related software or components simultaneously, they are also commonly used to distribute potentially unwanted applications (PUAs) or even malware.
Here are some tips on how to spot bundle installers:
Download Source: Be cautious of software downloaded from unofficial or questionable sources, as these are more likely to contain bundle installers. Stick to trusted websites and official download sources whenever possible.
Installation Process: Pay close attention to the installation process. Bundle installers often include additional software offers or options during installation. Read each installation screen carefully and uncheck any boxes for additional software that you do not want or need.
Custom Installation Option: Look for a custom or advanced installation option rather than a quick or recommended installation. Custom installation options typically allow you to see and deselect any bundled software offers, whereas quick installations may automatically include additional software without your consent.
Read EULA and Privacy Policies: Review the End User License Agreement (EULA) and privacy policies during installation. Bundle installers often disclose bundled software and their data collection practices in these documents, although they may be buried in lengthy text that many users skip over.
Software Reputation: Research the reputation of the software being bundled. If the bundled software is known to be potentially unwanted or malicious, it's best to avoid the bundle altogether.
Download Size: Be wary if the download size seems larger than expected for the software being installed. This could indicate additional bundled software included in the package.
Check Installation Directory: After installation, check the installation directory for any unfamiliar programs or files that may have been installed alongside the desired software. Remove any unwanted software promptly.
Use Trusted Antivirus Software: Utilize reputable antivirus or antimalware software that includes real-time protection to help detect and prevent the installation of potentially unwanted or malicious software.
