EnigmaSoft Threat Scorecard
EnigmaSoft Threat Scorecards are assessment reports for different malware threats which have been collected and analyzed by our research team. EnigmaSoft Threat Scorecards evaluate and rank threats using several metrics including real-world and potential risk factors, trends, frequency, prevalence, and persistence. EnigmaSoft Threat Scorecards are updated regularly based on our research data and metrics and are useful for a wide range of computer users, from end users seeking solutions to remove malware from their systems to security experts analyzing threats.
EnigmaSoft Threat Scorecards display a variety of useful information, including:
Popularity Rank: The ranking of a particular threat in EnigmaSoft’s Threat Database.
Severity Level: The determined severity level of an object, represented numerically, based on our risk modeling process and research, as explained in our Threat Assessment Criteria.
Infected Computers: The number of confirmed and suspected cases of a particular threat detected on infected computers as reported by SpyHunter.

PUA:Win32/MediaArena is an intrusive program that aims to get installed on a computer and perform various unwanted actions. MediaArena could take control of the user's Internet browser or deliver dubious advertisements on the system. MediaArena could be detected as a stand-alone program or a browser extension that is typically installed on the computer without the user's knowledge or permission. Once activated, this PUP (Potentially Unwanted Program) may start displaying pop-up advertisements and redirecting the user to different websites when it detects that the user is browsing the Internet. This can disrupt the entire browsing experience and, more importantly, take users to unsafe destinations.
In addition, PUA:Win32/MediaArena may collect the user's personal information and browsing history, which could be utilized for fraudulent purposes, such as identity theft or targeted advertising. This PUP must be removed as soon as possible to protect the user's privacy and security.

Users are Unlikely to Install MediaArena Knowingly
The distribution of PUPs like MediaArena often involves dubious tactics that aim to deceive and manipulate users into installing unwanted software on their devices. One such tactic is bundling, where PUPs are packaged alongside legitimate software and installed without the user's knowledge or consent. This is often done by hiding the PUP in the installation process and using confusing or misleading language in the installation prompts.
Another tactic is deceptive advertising, where PUPs are advertised as legitimate software or as valuable tools that will enhance the user's experience. In reality, these programs often perform unwanted actions such as displaying advertisements, redirecting the user's browser or collecting sensitive information.
Additionally, some PUPs may use social engineering tactics, such as fake security alerts or warnings, to convince users to download and install the unwanted software. This can trick users into thinking that their devices are infected with malware or that their privacy is at risk, leading them to install the PUP in an attempt to fix the problem.
Furthermore, some PUPs may use manipulative methods to prevent users from uninstalling them, such as hiding their files and processes or creating multiple entries in the device's Registry. This can make it challenging for PC users to remove the unwanted software and regain control of their devices.
Overall, the distribution of PUPs involves a range of dubious tactics that can harm users by compromising their privacy, security and overall experience with their devices. It is crucial for users to be cautious and vigilant when downloading and installing software and always wade through the terms and conditions before agreeing to install any program.

Digital Signatures
Digital Signatures
This section lists digital signatures that are attached to samples within this family. When analyzing and verifying digital signatures, it is important to confirm that the signature’s root authority is a well-known and trustworthy entity and that the status of the signature is good. Malware is often signed with non-trustworthy “Self Signed” digital signatures (which can be easily created by a malware author with no verification). Malware may also be signed by legitimate signatures that have an invalid status, and by signatures from questionable root authorities with fake or misleading “Signer” names.| Signer | Root | Status |
|---|---|---|
| STANIS LTD | GlobalSign Code Signing Root R45 | Root Not Trusted |
| VIEWBIX LTD | GlobalSign Code Signing Root R45 | Root Not Trusted |

Similar Families
Similar Families
This section lists other families that share similarities with this family, based on EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same packing and encryption techniques but uniquely extend functionality. Similar families may also share source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and network characteristics. Researchers leverage these similarities to rapidly and effectively triage file samples and extend malware detection rules.- MSIL.Agent.DFAY
