SmartFunctionSearch is a Possibly Unwanted Program (PUP), equipped with browser hijacker capabilities that targets Mac systems. In most cases, users may not have even noticed that SmartFunctionSearch has been installed on their devices due to the application's dubious or misleading distribution tactic. Some of them may include 'bundling' - the installation of SmartFunctionSearch is hidden inside the installation process of another more popular free application or poses as a software update.
No matter what the infiltration channel was, once inside a system, SmartFunctionSearch proceeds to enact its agenda. SmartFunctionSearch takes over certain browser settings to modify the homepage, new page tab, and the default search engine to open a fake search engine at SmartFunctionSearch. Infosec experts consider such engines to be fake due to their inability to conduct Web searches. Instead, they take the user's search query and redirect it through a legitimate engine such as search.yahoo.com.
SmartFunctionSearch can start delivering sponsored advertisements to the compromised device, tracking various browsing and system data, and potentially injecting third-party links in the list of search results displayed to the user. It is necessary to take the necessary steps to remover applications such as SmartFunctionSearch as soon as you realize that they are present on your device.
