# yodawg.jpg solution from OpenCTF 2018 *by Javantea* *Aug 12, 2018* yodawg.jpg is a standard steganography challenge. The main feature was that it was tricky in multiple ways. <img src="https://altsci.com/concepts/images/yodawg.jpg" alt="yodawg.jpg" /> The hint tells you that steghide was found on the computer. Steghide is a very old program that no longer compiles with standard and default configuration compilers, mostly due to C++ standards changing in ways that are not obvious to fix. Neg9 has a server which has steghide, so we were able to start testing right away. One of our team members started testing the Rock You wordlist. While this might have worked, it was not the way we solved it. After looking at another problem for hours and testing many different methods (including outguess just in case), I noticed that the image looked like a flag. I searched Google for green yellow blue flag and found that Gabon had a flag. A couple of tries found that the password to give steghide is "Gabon". This produced IHeardYouLikeFlags.jpg. This white image has the text "I heard you liked flags". No obvious solution was accepted, so I started steghide again. This time I tried the text on the image, flag, Gabon, and France. It was none of these, so I decided to test Rock You and it quickly found so.txt. I didn't figure out what the password was, but it's in the top of the Rock You list. The file so.txt contained the flag. <img src="https://altsci.com/concepts/images/IHeardYouLikeFlags.jpg" alt="IHeardYouLikeFlags.jpg" />
