Google's Play Store has revealed a major accident. A malicious software called "Expensive Wall" has infected more than 50 applications, and these applications have been downloaded about 1 million to 4 million times.

ExpensiveWall basically exists in wallpaper apps, and these malwares also bypass the built-in anti-virus protection mechanism of Play Store. After users install these infected apps, they will request various permissions, such as SMS messages and Internet access rights, and then send paid SMS messages to mobile phones.

If users do not pay attention to the permissions required by the app, it is difficult to ensure the security of the phone, and Expensive Wall is also difficult to be detected by Google's Play Store. At present, malware developers have a new way to bypass Google's security protection mechanism, so users should pay more attention to those apps that need to obtain a lot of permissions.
