Your assignment is to analyze this picture:
The original is at https://en.wikipedia.org/wiki/Main_Page#/media/File:Deerfire_high_res.jpg. Clearly, the two pictures appears to very similar, but doing a sha1sum shows that the files are clearly different:
$ diff Deerfire_high_res.jpg deerfire.jpg Binary files Deerfire_high_res.jpg and deerfire.jpg differ $ sha1sum Deerfire_high_res.jpg deerfire.jpg ce30a7f9b7706d3c1733393ad4150f93b56b1a4d Deerfire_high_res.jpg 30a4bb865637fda8e95f3e032fd1146d9414cf21 deerfire.jpg
I would recommend that you use your Caine image in the lab to do this analysis, since it does have the software to do this analysis (indeed, I created this via a Caine image running under QEMU.)
Please turn in your write-up at the beginning of class on Monday, April 8.
