Apps for Android devices are published on the PlayStore, after passing some quality filters. What happens is that these quality filters can sometimes not detect hidden malware in such applications.. This is the case of a QR code scanner, containing a Trojan.
It is not the first time that a case of these and, unfortunately, It won't be the last. The QR Code app & Barcode Scanner contains hidden TeaBot malware. When you first open the app, The user was prompted for permissions to upgrade, but this update does not come from the PlayStore but from GitHub sites that contained the malicious code stored. In this way, PlayStore controls are bypassed.
Google has already removed this application from its store, In addition to denouncing developers.
These cases teach us once again that you don't always have to trust all applications and that, In addition, We must be scrupulous when granting permissions to downloaded applications so as not to compromise our personal data.
