Find Me – Osint Challenge Writeup | BUP CTF Powered by Knight Squad - Qualification Round

I checked the ctf date and last update for this ctf on Facebook Page Knight Squad — and after that get the post where Knight Squad Team give the update and add a banner image. I checked the banner image properly and Get a tiny piece of cipher text under the image. Next identify cipher, which shown that it was Base92 encoded.

Steps I followed:

1. Checked the last update for BUPCTF & Get the post with a banner image
2. Downloaded/cropped the banner image from the Facebook.
3. Zoomed in and extracted the tiny cipher text.
4. Checked the cipher identifier → confirmed it was Base92.
5. Decoded the Base92 text, which revealed the flag.

Here somepart of the flag: BUPCTF{OMG_Y0O_

Best of luck finding it! Md Sabbir Mondol
