Android Malware Found in Apps

At least two apps available in the Google Play store have been found to contain an interesting form of malware. The apps Songs and Prized each contain malware, now known as KageCoin, that utilizes the device as a crypto-currency mining device. Crypto-currency mining is when a device uses a part of its processing power to facilitate crypto-currency transactions, and in return earns the owner (or malware attacker) a portion of the currency.
While annoying, the malware isn’t as bad as it could be. It only performs its mining actions while the device is charging. Because of this, its power consumption is less noticeable.
