Windows 10 New Feature Hunts and Thwarts PUAs/PUPs

Per reports, Microsoft has hinted that the next main version of Windows 10 will come stacked with a fresh security feature that would allow the users to facilitate the Windows Defender’s secret feature that helps hunt and bar the installation of known PUAs (Potentially Unwanted Applications).

PUA’s are also widely known as PUPs that stands for Potentially Unwanted Programs. These aren’t as well known by the users in the cyber-crime world as all the other major threats but are a valid threat nevertheless.

Per sources, these are software that is installed on devices via fooling the targets. The term for which the PUP/PUA stands is self-explanatory with regards to applications or programs that your device may not really need.

PUPs/PUAs go around with tactics like either by employing “silent installs” to dodge user permissions or by “bundling” an unrequired application with the installer of an authentic program.

Sources mention that PUAs most commonly contain applications that alter browser history, hinder security controls, install root certificates, track users and sell their data, and display invasive ads.

As per reports, the May 2020 update is to be rolled out to the users in the last week of this month. Microsoft mentioned that it has added a fresh new feature in its setting panel that would allow users to bar the installation of any unwanted applications or programs in the form of known PUAs/PUPs.

As it turns out, researchers mention that the feature has been available in the Windows Defender for quite a lot of time, but for it to kick start it would need group policies and not the usual Windows user interface.

As per sources, to enable the feature a user must go to ‘Start’, ‘Settings’, ‘Update & Security’, ‘Windows Security’, ‘App & Browser Control’, and finally 'Reputation-based Protection Settings’. Once updated, the feature would show two settings, the above-mentioned feature is disabled by default and would need to be enabled manually. However, Microsoft suggests, enabling both the settings.

Reports mention, that the “Block Apps” feature will scan for PUAs that have already been downloaded or installed, so if the user’s using a different browser Windows Security would intercept it after it’s downloaded. However, the “Block Downloads” feature hunts the PUAs while they are being downloaded.
