Google has just banned 50 "Android" applications from the "Play" store in response to personal information theft and interception of text messages. The latest group of troublesome applications was discovered by the security team at Zscaler, which found that they contained harmful malware including the notorious Joker vulnerability. Once installed, Joker has the ability to install hidden spyware and premium communication software on devices, which can then register unsuspecting users in expensive monthly subscription plans. Alongside Joker, these applications also posed other risks including the Coper malware that can intercept and send SMS messages, unlock the device's screen, prevent uninstallation, and allow attackers to control and execute commands. Another threat found within the apps is the malware Facestealer, known for targeting "Facebook" users with fake login screens in an attempt to steal usernames and passwords. The complete list of banned applications can be found through a link. Speaking on the threat, Zscaler stated: "The Google Play Store is typically considered one of the safest sources for users to find and install 'Android' applications. However, malicious actors continue to develop their tactics and manage to upload dangerous applications related to malware. The Zscaler ThreatLabz team recently discovered apps containing multiple instances of the Joker, Facestealer, and Coper malware spreading in the virtual marketplace. The ThreatLabz team immediately reported these newly identified threats to the Google Android Security team." Security experts advise caution before downloading any application unless it comes from a known and trusted source.
