This is the first sort of the question which can be said as the hacking a bit 🙂 Here is the question
There’s bound to be a key on the spaceport’s hidden website
Hint: Look very closely at the url and think about it a little
Here is the link of the website in case you missed the above link ( I can’t reproduce this one that easily 😛 ) https://picoctf.com/problems/getquery/index.php?admin=true
To solve this you need to have some basic understanding of the web and and how a query is done in the web form the url , but you needn’t know every thing as the clues and web pages makes us easy to solve this challenge
When you see the clue it says to look closely at the url
The web page in the above url has a button which says “get key”.
Go ahead and press it then it gets redirected to this page
which says that you are not the admin and this is not the competition .And if you look carefully at the url it changes from admin=true to admin=false and competition=ccdc. But if you didn’t notice the change in the url you might take some time to figure out the what is happening .
If you just change the url to admin=true and competition=picoctf we can you get this page
and here you go you get the flag
