Overview
Points: 50 Category: Binary Exploitation Note: very sketchy writeup because I don't know why what I did got a flag, it just worked
Description
We'd like to get your input on a couple things. Think you can answer my questions correctly? in.py nc mercury.picoctf.net 61858.
Hints
- What version of python am I running?
Approach
nc mercury.picoctf.net 61858 to connect to server. I took a look at in.py and noticed the city variable would be something that's unavailable to us. Upon careful inspection, it seems no matter what number is given, as long as it isn't nothing (or not a number) then it will continue onto the next section. I didn't know which cities were in the file city_names.txt so I just inputted "city" and it gave a flag.
