Google has removed over 500 malicious apps from its Play Store following US-based cyber-security firm Lookout report on spyware threats these apps pose on the OS. The apps discovered by the security firm were found containing a secret backdoor that allowed developers to install a range of spyware at time. According to Lookout, the apps used a software development kit called lgexin to siphon user's personal data on the device, with no warning. The software allowed these apps to connect to ad network and deliver ads that are targeted to the specific interests of end users. If, in case, a malicious version of the software was installed, the developer kit could be updated to launch spyware threats. The malicious spy apps included mobile games for teenagers, weather apps, internet radio, photo editors and travel were noticed affected by the software. In a statement to Ars Technica Google said: "We've taken action on these apps in Play, and automatically secured previously downloaded versions of them as well. We appreciate contributions from the research community that help keep Android safe."
