Download the Duck.png for the challenge.

Use strings on de Duck.png, where you can see the string in Base64:
``` nUE0pUZ6Yl93q3phoJIxnJSznKWyYzAioF9znJkyY3E3AwHjoGM6BGW1oGDjpP9RqJAerF5dpTpiMzyfMD== ```

Decode from Base64 and get the mediafire link:

[https://www.mediafire.com/file/tw650m6z92um40p/Ducky.jpg/file ](http://).

Then use the text in the image you got (``` DON'T DUCK WITH ME ```) as a passphrase in steghide with the Ducky.jpg, something like this should do:

``` steghide extract -sf Ducky.jpg -p "DON'T DUCK WITH ME" ``` , you can use other tools, tho .

With this you get a zip named Gooooooose.zip, now you can extract it, and get a image named Gooooooose.jpeg, then just use the strings with the grep command to get the flag. Like this ``` strings Gooooooose.jpeg | grep 'CTF.*' ```.
