The main presentation was by Andy Bair of MITRE. Andy and his team
from Korelogic [0] finished first in the recent Digital Forensic
Research Workshop 2006 Data Carving Challenge [1]. Andy described the
challenge: 50 Mb of data with no known start or end points, file
types, state of fragmentation, etc., and the techniques his team used
to analyze the data, extending and modifying tools the team had
previously developed (FTimes [2] , XMagic) and using common UNIX
tools like dd, bvi and file to identify file start and end-points and
"carve" the files from the data sample and verify them. Andy
estimated his team devoted 550 hours to the challenge, but with the
development of the (Open Source) tools and methodologies[3] they
created, could repeat the feat in around 100 hours. Andy said his
team is continuing to develop their tools with the goal of automating
as much of the process as possible.
A very interesting presentation. Thanks, Andy, for the presentation,
thanks to Heather for running the event, and to Martha's Exchange for
use of the room.
