Over 1 billion downloads and various security flaws

As the researchers specify, after analyzing the application code, several gaps were discovered. Some of them could lead to remote code execution threats. In fact, it has been possible to verify how it is possible exploit vulnerability through a fake application created specifically for that purpose, capable of obtaining read / write permissions through SHAREIt.

This allows install third party apps without the need for the user to grant express permission, using the tools integrated in SHAREIt.

“SHAREIt also provides a feature that can install an APK with the filename suffix sapk. This function can be used to install a malicious application; if that's the case, it will enable a limited RCE when the user clicks on a URL. “

Actually, Google has already been informed of the problem, and hopefully the company will take action on it, probably removing the app from the store temporarily.
