App stole photos of my credit cards and charged them

I downloaded a free App from the app store called Translator+ created by Rocket Apps GambH and gave it permission to access my photos in order to translate a document. It was a useless app and I ended up deleting it. I have a photo album called “documents” in my phone with scans of my ID and several credit cards, and a few hours later all the credit cards in that folder were charged by AmazonPrime for amounts in the range of 100-150 dollars. I hardly download apps, I am convinced this app scanned my photos, probably looking specifically for a documents folder containing credit card images, and uploaded them. How can i stop this app scamming others? How can such apps get into the Apple App Store, i though it was supposed to be safe?
