Hi folks,

here is my Hackvent write-up. It was a really good CTF, but there was a really dump challenges. It was a challenge, where you called a number in switzerland. Also you needed a provider, who fakes the displaynumber of your calls. At the end I spend about 30€ to solve that challenge. If you want to try it by yourself, you can do it here. Remember, every try costs you round about 50 cent or something like this and calling robots are not so fast in the answer, like webservers ;)
