Mac users have a new PUP (Potentially Unwanted Program) to be on the lookout for. Named ProcessBrand, this dubious application combines the functionality of adware and a browser hijacker. For their distribution, PUPs rely on underhanded techniques such as bundling or being injected into fake software installers/updaters almost exclusively. Users must be careful when installing freeware applications or products from less reputable sources.
If ProcessBrand manages to install itself on the user's Mac system, it will start generating intrusive advertisements, while also taking control over the Web browser. The delivered advertisements could employ clickbait messages and lead to untrustworthy third-party websites. As for the user's Web browser, its settings (most likely the homepage, new tab page, and the default search engine) with be modified to open a promoted address. Typically, browser hijackers are used as a vehicle in the promotion of fake search engines. Searchers conduct via such engines can produce misleading results riddled with sponsored advertisements.
While present on the system, PUPs could try to spy on the users browsing activities. The unwanted applications might access the entire browsing history, search history and any clicked URL. The gathered data could then be uploaded to a remote server.
It is strongly recommended to pay attention when installing applications. If you fear that PUPs may have already infiltrated your Mac, perform a thorough scan with a professional security solution and see if it manages to detect any suspicious items.
