Beware! New Android Malware Infected 2 Million Google Play Store Users

Checkpoint researchers of security measures found that malware "FalseGuide" is loaded in over 40 types of guide applications registered in the Google Play store. Although it is an application with FalseGuide that was supposed to be downloaded to 600 thousands of terminals in February 2017, according to a subsequent check of Check Point, the oldest one was registered in the Google Play Store in November 2016 , It was registered in a condition that it can be downloaded for about five months until April 2017 without seeing wrongs, and it turned out that more than 2 million people were damaged.

Applications containing FalseGuide will prompt for administrator privileges during installation, and if you agree to this, will prevent users from deleting applications. After that, the malware registered the terminal in the cross platform service "Firebase Cloud Messaging" for the application developer to send the message. An attacker sends a linked message to the terminal, installs it, displays incorrect pop-up advertisement, and obtains advertisement income.

However, even after the application is deleted from the Google Play Store, there are still active applications on the user's terminal, and the damage is still considered to continue.

Also, unlike apps from major application makers such as games, guide applications can be developed with even a small veteran, so it is also a cobblestone, there may be aspects where it is easy for users to make a mistake in selecting applications. Either way, from the fact that the malware-included application was mixed also in the regular Google Play store, at the time of downloading and installing the application, it is necessary to investigate beforehand whether the application is reliable before installing it, The user side seems to be required to respond.
