The Federal Trade Commission and New Jersey Attorney General have settled charges with a developer who created a mobile rewards app that in actuality hijacked users phones in order to mine cryptocurrencies. Ryan Ramminger, the CEO of Equiliv Investments, created an Android app called Prized that offered points to those who downloaded the app and then either played games or installed other affiliate applications. Once activated, the app drained users’ device batteries and consumed their mobile data, which might have caused some victims to incur fees if they went over their monthly data limits.”]
