The Joker mobile trojan is back on Google Play, with an uptick in malicious Android applications that hide the billing-fraud malware, researchers said. At least 1,000 new samples have been detected just since September, many of them finding their way into the official marketplace. The developers of the latest versions of Joker are taking advantage of legitimate developer techniques to hide the actual intent of the payload from traditional, legacy-based mobile security toolsets, according to a Zimperium analysis. The new samples also take extra precautions to remain hidden after a trojanized app is installed.
