Going through Stego tricks on HackTricks (https://book.hacktricks.xyz/stego/stego-tricks) we find FFTStegPic at https://github.com/0xcomposure/FFTStegPic. 

 

git clone https://github.com/0xcomposure/FFTStegPic

Go ahead and run the:

 

pip3 install opencv-python

 

just to cover all the bases.

When we try to run the FFTStegPic.py script, it asks us for the FULL path to the image. We can't use ../ trust me I tried.  Once we give it the full path, an image pops up with the flag!
