Level 2 of OverTheWire’s Natas wargame is a little more fun than the previous two. It’s also pretty simple, though.
You start out on a page that tells you that there is nothing on it.
Like previous levels, I then viewed the source to see what was in the code.
It appears that there’s a 1x1 pixel image present on the page. It’s located in a “files” directory of the webserver. I decided to see if there was anything else in that folder, and found a “users.txt” file.
Once I viewed the “users.txt” file, it displayed the next level’s password.
