Can you help find which image file may contain a hidden message? Extra points for deciphering it as well..!
We have reasons to believe that the ongoing Rio Olympics (2016) is under a threat. We have intercepted images circulating between some wanted criminals, and we believe that one of these images has a hidden message. I am referring to 'steganography'. This is a technique used very popularly by the terrorists, where a message is hidden within an image before it is circulated. You may read more about it on Wikipedia (link here).
Now, we were lucky enough to capture multiple versions of the same image. The question is which one of these has the hidden message? If we can identify the name of the file, which contains the secret message, we could run the file thru our super-computers to decipher it.
The mission, if you chose to accept it, is to identify the image which you believe could hold the secret message. If you are able to break the encryption and extract the hidden message it would be extremely helpful as well. However, it would also suffice, if you can tell us the file-name of the container carrying the secret message.
-1- Investigate the provided images, and submit the name of the file which contains a hidden message.
-2- Bonus points [optional]: Extract the secret message in it and submit the contents of it.
