Every time someone claims they've written a "bulletproof" app, I roll my eyes so hard I can practically see my brain. History's not on their side, and in this endless cat-and-mouse game between developers and hackers, it never will be.
This is for you, my friend. I know you follow me here, so consider this a friendly reminder from, well, nobody.
You know, they say the only way to write a truly secure app is to create an empty file or repo. But even then, some JabaScript-powered IDE will probably crash trying to open it, and boom! You've got a security vulnerability.
@nixCraft It's easy, for a truly secure app, simply have no internet connection or external port connection to the machine!
