The Art Of Steganography

In this challenge I got the chance to review my steganography skills.

The Description of the challenge was as follows :

My friend wanted to install an antivirus for his computer, but the creator of the antivirus was caught!

and we were provided with an image : gif file

The Gif Image that we were provided.

Steganography is the art of hiding a secret message or files inside an image, I took the information provided and did more digging to find more clues.

By using the command “file AV.gif” I can know more about what the file is and it’s properties >

As shown in the following image :

Gif Image Properties and Details.

the thing that caught my attention is this text : “version 89a” afterwards and after searching the web about this term I found an article that helped me solve this challenge.

and the next website that helped me upload the image and examine it is : StegOnline.com

As we can see here and after uploading the image file to the website we can find a base64 encoded text after clicking on the show strings button after decoding it using base64 on the terminal I got the flag and managed to solve the challenge which was relatively straight forward.

And Here I managed to Grab the flag and complete the Challenge.

Thanks everyone for reading my write up and stay tuned for the next!
