Apple has removed Adware Doctor, a popular paid anti-adware application for macOS, from the App Store. Several security researchers have shown that the app among other things passes browser history and an overview of running processes to a web server.
According to the researchers, the app was ranked first in the ‘most popular paid apps’ category. It was perhaps precisely that popularity that gave users the app permission to browse in the Home folder. The further steps the app takes are listed in a proof of concept video that the original discoverer put on YouTube.
Besides spying, according to the researchers, the reviews for the app are probably also fake . They base that on the overly positive tone that the reviews have. The application was rather through life under the names AdBlock Master and Adware Medic, not to be confused with AdwareMedic, without space, from Malwarebytes. According to Patrick Wardle of Digita Security, the server to which the data is sent is currently offline.
