Its interesting that since publishing this at least two other bits of smartphone based mining malware has appeared.

clearly these malware authors have too much time on their hands I mean unless you harness multiple thousands of smartphones together and make a bitcoin mining smartphone botnet theres no way you can make enough money to make this worthwhile.

It does speak to the entrepreneurial nature of malware authors though. Rather than create more wallet stealers, these guys are constantly striving to find a new "magic malware quadrant"
