Hackers have infected thousands of Android phones and smart TVs and used the devices to mine for cryptocurrency, researchers at Chinese cybersecurity firm Netlab360 found.

The attack combines a handful of well known hacking techniques with one goal in mind: use the processing power of internet connected devices to create more Monero, a digital currency that can be replicated by running a program on a computerized device. According to ZDNet, the attack affected 7,000 devices in China. While that's not as big as some recent networks of hacked devices -- called botnets -- security experts believe hackers will increasingly use this approach to make money off of other people's computers, smart home devices, phones and tablets.
