For this challenge, we were given a python script: import socket def menu(): print("______________________") print("| MENU |") print("| 1) see option |") print("| 2) edit option |") print("| 3) connect |") print("______________________") print(""" ______ __ __ ______ / \ / | / | / \ /$$$$$$ | ________ $$ | __ ______ $$ |____ ______ _______ _______ /$$$$$$ | $$ |__$$ |/ |$$ | / | / \ $$ \ / \ / \ / |$$____$$ | $$ $$ |$$$$$$$$/ $$ |_/$$/ $$$$$$ |$$$$$$$ | $$$$$$ |$$$$$$$ | /$$$$$$$/ / $$/ $$$$$$$$ | / $$/ $$ $$< / $$ |$$ | $$ | / $$ |$$ | $$ | $$ | /$$$$$$/ $$ | $$ | /$$$$/__ $$$$$$ \ /$$$$$$$ |$$ |__$$ |/$$$$$$$ |$$ | $$ | $$ \_____ $$ |_____ $$ | $$ |/$$ |$$ | $$ |$$ $$ |$$ $$/ $$ $$ |$$ | $$ | $$ |$$ | $$/ $$/ $$$$$$$$/ $$/ $$/ $$$$$$$/ $$$$$$$/ $$$$$$$/ $$/ $$/ $$$$$$$/ $$$$$$$$/ -----=[Azkaban C2 v.

This challenge involved solving an ASCII maze in under 10 seconds. I can’t include a demo because I’m writing this after the CTF ended. My script uses the astar package, because I was too lazy to re-implement A* manually. It isn’t particularly pretty, but at least it is functionnal. Here it is: import math from pwn import * from astar import AStar def parse_maze(source): source = source.strip() source = source.split('\n') source = source[:-1] # Remove last line (dots) source = [list(l[1:-1]) for l in source] # Remove left and right dots return source # Mostly copied from the astar package example.
