Find hidden messages in image files
People hide messages in images for a lot of reasons. In this lab we will see if you can find hidden messages in images that are presented on the course webpage.
Submit a list that looks like the following, except the messages and procedures stated below for finding messages and analysing files may not be correct for the associated image file:
erc2.jpg: message: how about that procedure: I took a close look with my brand new glasses that give me 20/20 vision mainstreet.jpg: message: roses are blue and violets are red! procedure: I was able to decrypt using steghide with the following command line: steghide extract -sf mainstreet.jpg -xf whoa.txt and whoa.txt contains the hidden message erdos.jpg message: none procedure: I applied steganalysis.exe, which is a windows program, using the following procedure: double click the steganalysis icon on the desktop, drop the file menu, select "Open", select erdos.jpg, drop the analysis menu, select "Hail Mary." The results window indicates a high probability of no embedded file or text. ...This is not a group project. Use Blackboard for submission. You get 3 brownies for each correct answer for a maximum of 18!
In case you did not know, you need to download the images and work on them locally.
