Cryptocurrency mining is a hot and trending topic at the moment, especially since websites have recently resorted to mining cryptocurrency instead of showing ads. As with many malicious trends, the cybercriminals have quickly moved from PC to mobile. This week, we found an app that contains cryptocurrency mining capabilities on the Google Play Store, masquerading as the Cooee game. Between 1,000 and 5,000 users downloaded the app. We detect the malware as JSMiner and we informed Google of the app yesterday.
