Hacked Google In App Purchase?

Some guy uploaded the video to YouTube that using some kind of IAP Hack to purchase IAP item free(Attached screenshot).

I guess this guy who developed that program:

Seems like it’s old exploit but looks like it still works. How to prevent that illegal purchase?

I doubt this still works. It’s from 2013! What makes you think it still works?

Because I saw it worked on the video uploaded yesterday. Check the screenshot attached. I’m not sure that’s the same program since the author published 2013, but I can clearly see who made that program, exactly the same name texted on the application, and video that used that application and hacked iap was uploaded yesterday. Means that some guy used Billing Hack Application in 2020.

From the screenshot, the author & programmer is Dominik Dschuermann which is exactly the same name so I can guess the same developer made some kind of “improved version” and it still works in 2020.

The video I saw a man used that program uploaded that yesterday, he used it in my game.

No one?

Can you link the video from the screenshot?

The video was deleted but I downloaded the video before it was deleted. If you need it, I can share the link to see the backup one.
