Recently a malware was found in the popular android app CamScanner. The app is now removed from Google Play store.
The company has also acknowledged the existence of the malware in an official statement. This article shows the statement saying version 5.11.7 is affected.
I have the app installed in my phone for a long time. It looks like last I had updated it in march. The version is 126.96.36.19990312 as shown in the app.
So, since the app is older version than mentioned in their statement, is it safe to continue using it as far as this particular malware is concerned?
