LevelNight

LevelNight is classified by cybersecurity researchers as a rogue application. It is aimed at Mac users and its primary focus appears to be the delivery of unwanted advertisements. Not only is LevelNight an adware application but it also belongs to the AdLoad adware family. Programs of this type are rarely distributed through normal channels, as users are extremely unlikely to download and install them willingly. Instead, adware, browser hijackers, and other dubious applications could be included in software bundles, fake installers, etc. The reliance on such tactics makes them PUPs (Potentially Unwanted Programs, as well.

The first sign of adware activity is the sudden and frequent appearance of unwanted advertisements. The advertisements could take the form of pop-ups, notifications, banners, etc. More importantly, advertisements delivered by adware are highly likely to promote untrustworthy destinations, such as hoax websites, fake giveaways, dubious online betting/gaming platforms and more.

And while the advertisements occupy the attention of the user, these PUPs could silently perform additional invasive actions in the background of the system. After all, PUPs are notorious for having data-harvesting capabilities. They monitor users' browsing activities, collect device details, or, in some extreme cases, attempt to extract account credentials or banking details from browsers' autofill data.
