We are given a picture . Its a stego challenge so lets go direct to setgsolve to find something interesting at the lsb .
As you can see there are some data at the lsb of colour red the same with green and blue. Extracting them … Go to analyze->data extract
we clearly see that there is a png image . Go and save it as a .png …
We dont have the flag yet. By performing the same steps again we can see that there is a hidden string inside at the lsb but its not the flag ! Time to binwalk this picture .
There is a zip file inside this picture. Use foremost or binwalk to extract that file .
Trying to “unzip” produces an error “need PK compat. v5.1 (can do v4.6)” . 7z does the job and extracts the flag.txt file with the password that we found later , at the lsb of the devils picture !
Sadly I couldnt solve the stego200 or stego300 . There are so much more to learn 🙂
Have fun !
