Web based levels in "CTF BISMARCK" ;)

This CTF is developed to demonstrate vulnerabilities that are beyond from typical vulnerabilities such as XSS (Cross-Site Scripting), SQLi (SQL Injection) and WordPress thus these CTF challenges are contained with stuff like hash cracking, reverse engineering, request manipulation and so on.
