Recently there's been some concern about malware in the Android Marketplace. Hackers have been repackaging legitimate Android applications with spyware embedded and resubmitting them, causing mobile devices to be infected with malware after download. Here's some official words from Linda Liu, Global Marketing Director of the mobile security firm NetQin, on the steps Google is taking to combat the trend:
Recently, a new spyware named "DroidDream" causing privacy leakage was found on Google's Android Market. The spyware was embedded in repackaged legitimate applications and uploaded to the Android Market by the developers "Myournet", "Kingmall2010" and "we20090202". Mobile devices will be infected after download. Google has removed more than 50 infected applications from Android Market and remote deleted the infected apps downloaded to the users' devices to prevent further spreading of the malware. Even though Google has taken a series of control measures in the wake of the event, there seems to be a need for more to be done.
