Digital Forensics Research Workshop Challenge

Every year the DFRWS guys put on a great forensic challenge and this year was no different. While last years challenge was very hard and not that realistic, this years challenge was designed to reflect what many people would experience in their work. The challenge was a simulated incident which involved network traffic, some file forensics and Linux memory forensics.

On the positive side it is quite easy to get something from the challenge. Pretty much anyone can have a go with this challenge and get something (You can probably even solve it using commercial tools !!). Thats a very good aspect of this years challenge - I'm sure it will be used for training for many years to come.

The negative side is that it becomes difficult to do something extra ordinary in order to win the challenge. Just getting the right answer is not going to cut it because many others can get the right answer. We needed to get the right answer in style... Our tools need to be better and look nicer and also be easier to use. Unless, of course, we missed something blatantly obvious....

This year I was lucky enough to be involved with the great team of David Collett and Aaron Walters. These guys are brilliant and each brings their own unique skills to the table. I believe this made our submission well rounded and certainly better than what each of us could have done on our own. Regardless of whether we are lucky enough to place first, I think we did great and certainly developed pyflag in new directions and added some very cool features - so it was well worth it.

We actually took guidance from the perp (now i sound like a real CSI) and decided to use google docs for collaborative editing. Thats a great product and works very well considering that we tried to collaborate on a 50 page document with many screen shots and images. As a bonus you can publish the document when you are finished:

Getting the paper in on time was a tremendous effort and well done to the team for foregoing sleep and time with their loved ones to make it happen....

It turned out to be a really cool document with a pyflag walkthrough of a realistic scenario. Hopefully people can read it and get a better idea of how to use pyflag from it.
