[Security - WebGL] Can hacker read data in buffer?

Hi guys, can hacker read data when game is running?

For example: In game, I create an public array [0,9,6,6,9,0,8,9,0,7]. This script was attached to an object in game.

I wonder that, if I build this game in WebGL/Andoir/iOS, could hacker read this array?

Thank you.

 

Trivially.

 

Anything stored on the user's computer whether in the processor, in memory, or in storage can be read by the user.

 

Sometimes it doesn't even have to be active memory!

...though this might have limited practical application when deterring game hacking.

 

a WebGL build is entirely downloaded on to the end-user's system, so nothing you do in WebGL can ever be secure from the end-user. Typically, if you need something unhackable, then you need a separate server-side application that your game connects to.
