Exercise $1-$ Is there something here?

There are three images that may or may not contain hidden information. Use the tools on

your favourite forensics distro to evaluate and identify whether the images have been altered

and if they contain any information. The images are:

$$ Image $1.$jpg

$$ Image $2.$jpg

$$ Image $3.$jpg

$1.$ Have any of the images been altered from the original and if so$,$ when and by whom...and

how?

$2.$ Is there any hidden information in any of the images, if so$,$ how did it get there, who put

it there, when did they do it and how did they do it$?$

$3.$ If there is hidden information, what is the information content and type?

$4.$ Describe the tools and techniques you used to both investigate and then document your

process.
