VERY IMPORTANT

McAfee’s Mobile Research team recently learned of a new malicious Android application masquerading as a plugin for a transportation application series developed by a South Korean developer. The series provides a range of information for each region of South Korea, such as bus stop locations, bus arrival times and so on. There are a total of four apps in the series, with three of them available from Google Play since 2013 and the other from around 2017. Currently, all four apps have been removed from Google Play while the fake plugin itself was never uploaded to the store. While analyzing the fake plugin, we were looking for initial downloaders and additional payloads – we discovered one specific version of each app in the series (uploaded at the same date) which was dropping malware onto the devices on which they were installed, explaining their removal from Google Play after 5 years of development.
