Hi Jonas,
I'm sorry to hear the back of your Galaxy S8 suddenly cracked. If you're in the Netherlands and your phone is bought in Europe, you could visit one of Samsung's service centers and explain what happened there. You could use the map on the bottom of this page to locate a service center nearby: https://www.samsung.com/nl/reparatie/mobile/bezoek-servicelocatie/ Just enter a city in this field, such as Amsterdam, like shown in the screenshot below, then press the search icon and the map will show the address of the nearest service center.
I cannot guarantee it will be covered by the warranty, but they can try to determine the cause of the the cracks in your phone. If the cause is an issue with the device, such as a slightly swollen battery, it might be covered by the warranty.
