DFIR Summit 2014

Filesystem Journal Forensics

• New Perspectives From Another Year of Research
• David Cowen, Partner, G-C Partners
• Thursday, June 5th, 6:45pm - 7:45pm

Journaled file systems have been a part of modern file systems for years but the science of computer forensics has only been approaching them mainly as a method of recovering deleted files. In this talk we will outline the three major file systems in use today that utilize journaling (NTFS, EXT3/4, HFS+) and explain what is stored and its impact on your investigations. We will discuss NTFS and new analysis techniques:

ï§Recover data hidden or destroyed by anti forensics

ï§Determine exact deletion times

ï§Determine what was being accessed and how often
