Check Your Hash Values

I fully converted my Windows 8.1 virtual machine into a server box today and set up a default C#.NET website that can be accessed over my local network. In wanting to learn Burp Suite for application testing, I wanted to make sure I could build and test vulnerable applications, since I learn better that way.

Well, I realized there were a lot of things I would want to test over the network from my Windows laptop, but setting up the appropriate testing programs on the laptop just was not feasible. I had a Kali virtual machine installed, but loading it would often bring the system to a crawl, so I decided that dual booting Kali would be the best solution.

Several failed installs, two wasted DVD-Rs, and several hours later, I realized that the Kali ISO I was using was a partial download on my Linux box that had caused me some trouble in the past. And I had forgotten to delete it. My go-to ISO was on my other Windows box (you can tell I enjoy operating systems, no?), and it has the proper SHA1SUM.

Oh, and for the record, that sum for the 64-bit 2016.1 version is deaa41c5c8f26b7854cafb34b6f1b567871c4875 . I had to use the wayback machine to get this, since they recently released the 64-bit 2016.2 version, which has a hash of 25cc6d53a8bd8886fcb468eb4fbb4cdfac895c65 . Finding that online was nearly impossible, which is surprising to me but a good reminder that I am responsible for my own documentation.

Just one…

sudo dd if=<myfolder>/kali-linux-2016.1-amd64.iso of=/dev/sdf

…later, and things are happy.

So I just wanted to share, please check your hash values. And while you’re at it, don’t leave corrupted files around.
