Threat Database Mac Malware FrequencySkill


FrequencySkill is an adware application designed to target Mac users. The application relies on dubious distribution tactics to hide its installation from the user such as bundling or via fake software updaters/installers. This behavior also classifies FrequencySkill as a PUP (Potentially Unwanted Program). In addition, the application also exhibits certain browser hijacker traits.

The main purpose of FrequencySkill is to monetize its presence on the user's computer by running an intrusive advertising campaign. Its activities might manifest as numerous unwanted pop-ups, banners, surveys, etc. that could diminish the browsing experience on the affected device severely. Clicking on any of the presented advertisements is strongly discouraged, as they could lead to unsafe third-party websites.

FrequencySkill also will take over the user's Web browser and more specifically the homepage, new tab page, and the default search engine settings. The goal is to then set them to open a promoted address that will be used as a search engine and receive artificial traffic whenever the browser is opened or a tab is started. FrequencySkill promoted two different fake search engines depending on the browser of the user. The PUP will cause the Safari browser to open the address, while Google Chrome will be forced to open

The search engines promoted through browser hijackers can provide any search results on their own seldomly. Instead, they rely on legitimate engines such as Yahoo, Bing, or Chrome for the list of results presented to the user. However, keep in mind that sponsored advertisements could be injected into the result list even if they do not meet the search criteria.

It is recommended to remove FrequencySkill from your computer as soon as you notice the first signs of the PUP's presence with a professional anti-malware solution, preferably.
