Hello Everyone!
I’m Tareq from Knight Squad.
Recently we played RCTS CERT CTF 2021. Here I’m going to give you a quick writeup for the challenge named “Maybe the Helper Can Help”. let’s dig into it.
In this challenge we were provided with a jpg image file. I was stuck in this challenge for a long time. I have ran binwalk, foremost, strings, exiftool but didn’t found anything.
After that I got a clue from another ctf player. He told me to bruteforce the password. And I got it. There’s a file inside this image file which has been embed with steghide.
I used stegseek. You can download stegseek from here .
So I ran stegseek & bruteforced for the password with rockyou.txt.
Command : stegseek <file> <wordlist>

The password was rosy. It extracted a txt file which contained base64 encoded data. I just decoded it from base64 twice & got the flag. This was really very exciting challenge for me..
