Topic: Web Exploitation
Flag Format: IHC_CTF{}
CTF Link: https://t.me/ctf_invisiblehc/12
Description:
Cookie is my favorite. Do you like cookie?
Find the flag in this site.
Solution:
the following site looks like:
In the first step, we need to inspect the cookies present on the website. We can use the browser's developer tools (usually accessed by right-clicking and selecting "Inspect" or pressing F12) to view the cookies associated with the webpage. In the "Application" or "Storage" tab, we can find and analyze the cookies.
After identifying the cookies, we should notice a cookie named "flag"
However, its value is encrypted.
To decrypt it, let's use CyberChef.
We first decode the cipher text and get binary text. After decoding the binary, we obtain a hex code, and by decoding the hex, we finally find the flag:
