AnalyserKey is another dubious ad-supported application that is targeting Mac users. It relies on deceptive distribution tactics to spread itself, as users are extremely unlikely to download and install such an application willingly. Once established on the system, AnalyserKey will begin generating intrusive advertisements that could impact the user experience drastically. Furthermore, the advertisements could promote questionable third-party pages, online tactics, phishing schemes, or domains offering other barely-functional PUPs (Potentially Unwanted Programs).
At the same time, AnalyserKey will take control over the user's Web browser in a typical browser hijacker manner. The goal is to promote a sponsored address, in nearly all cases that of a fake search engine. Browser hijackers usually modify the homepage, new tab page, and the default search engine of the browser. Users should not rely on these search engines to produce meaningful results. Fake engines either redirect to a legitimate engine such as Yahoo, Bing, or Chrome or initiate a redirect change that may involve several dubious engines. Ultimately, the list of results displayed to the user may include numerous dubious sponsored ad links.
Most PUPs similar to AnalyserKey also possess data-harvesting capabilities. They are after the user's browsing history, search history, and clicked URLs but the obtained information also could include various device details (IP address, geolocation, ISP, etc.) Some PUP could even try to access sensitive information such as payment details or credit/debit card numbers.
