Need Suggestions!: App icon

Kindly take a look at my app below:

I want to change the icon to better convey what the app is about.
Right now, it’s an internet globe inside a shield. I was trying to symbolize “Protecting the internet” or something like that, given that my app contains tutorials for ethical hacking.

I’m totally stumped when it comes to graphics, what should I change the icon to?
Any suggestions will be much appreciated :slight_smile:

nothing portrays the word hacker/hacking than the iconic guy fawkes mask. Possibly creating an overlay with the mask and the shield could be cool.
