I solved it in less than 1 hour, especially thanks to an hint within the comments below. Nevertheless, i have learned something new (especially to look beyond my own backyard: the weakness exploited to solve this challenge has always been under my eyes, just never thought about it) ... Thanks for the nice challenge ...
