Visualizing Entropy in Binary Files

Author of the post here. I&#x27;m working on a browser-based interactive analysis tool based on these visualizations. It&#x27;s nowhere near ready for release, but those who are interested can find a demo here:<p><a href="http://binvis.io" rel="nofollow">http:&#x2F;&#x2F;binvis.io</a><p>This is not even an alpha yet - I plan to announce the initial release in the next month or so. Eventually, I would like to add the ability to upload, share and annotate files for analysis. Comments and criticisms welcome!

Have a look at Cantor Dust [1], a visual reverse-engineering program that is promising.<p>The author says in a presentation [2] that CD is based on Cortesi&#x27;s work.<p>[1] <a href="https://sites.google.com/site/xxcantorxdustxx/visual-re" rel="nofollow">https:&#x2F;&#x2F;sites.google.com&#x2F;site&#x2F;xxcantorxdustxx&#x2F;visual-re</a><p>[2] <a href="https://www.youtube.com/watch?v=4bM3Gut1hIk" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=4bM3Gut1hIk</a><p>Here is a demo: <a href="https://media.blackhat.com/bh-us-12/Arsenal/Domas/_cantor.dust_.7z.zip" rel="nofollow">https:&#x2F;&#x2F;media.blackhat.com&#x2F;bh-us-12&#x2F;Arsenal&#x2F;Domas&#x2F;_cantor.du...</a>

These images remind me of Piet[1], an esoteric programming language where the programs <i>are</i> images. There you see the structure of the algorithm, rather than the binary, visually presented.<p>[1] <a href="http://www.dangermouse.net/esoteric/piet/samples.html" rel="nofollow">http:&#x2F;&#x2F;www.dangermouse.net&#x2F;esoteric&#x2F;piet&#x2F;samples.html</a>

This reminds me of a tool that came out 10 or 15 years ago, which allowed you to feed it arbitrary binary data that it could display in 3D.<p>I remember reading a Slashdot article on it in which one of the examples was a 3D, freely-rotating view of the Linux kernel binary.<p>Does anyone know what I&#x27;m talking about? I can&#x27;t seem to recall the name of the project or find it.<p>Also related:<p><a href="http://vimeo.com/110257380" rel="nofollow">http:&#x2F;&#x2F;vimeo.com&#x2F;110257380</a><p><a href="http://gynvael.coldwind.pl/?id=199" rel="nofollow">http:&#x2F;&#x2F;gynvael.coldwind.pl&#x2F;?id=199</a><p><a href="https://www.youtube.com/watch?v=5f7hZBoEwV0" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=5f7hZBoEwV0</a><p><a href="https://github.com/pwaller/binview" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;pwaller&#x2F;binview</a>

Perhaps a naive question but... what is this useful for?
