in this level we need to change the HTTP-header, to fake our web browser.

wget http://trythis0ne.com/levels/web-challanges/1337B/pwd.php --header="User-Agent: 1337Browser_V3.1"

i run this command in wsl, and then open the file pwd.php to see the output: GoodWork! the password is lizirulezzz :)

Flag: lizirulezzz
