There are some simple common sense steps to avoid this type of malware:
- Don't give any app admin access
- Don't install any app from a porn site that requires you to install before viewing a video.
- Android devices will be able to play videos without the need to install a specific app,
- Always check the download in VirusTotal before installing or at least google any link that seems a bit "fishy"
- Try to stick to office app-stores such as google and amazon.
