Contents

Stored Data Forensics

Flash Forensics

  • Access the physical layer of SD cards and/or USB flash devices. Reverse-engineer the Flash Translation Layer to find deleted data and files.

SleuthKit Enhancements

  • Support for YAFFS2 flash file system. (YAFFS2 is currently used on the Google G1 phone.)
  • Support for JFFS2 flash file system. (JFFS2 is currently used on the One Laptop Per Child laptop.)
  • Write a FUSE-based mounter for SleuthKit, so that disk images can be forensically mounted using TSK. (I've already started on this if you want the code.)
  • Add support for NTFS encrypted files.
  • Report the physical location on disk of compressed files.

fiwalk Enhancements

  • Automatically

Stream Forensics

  • Process the entire disk with one pass, or at most two, to minimize seek time.

Evidence Falsification

  • Automatically detect falsified digital evidence.

Sanitization

  • Detect and diagnose sanitization attempts.


AFF Enhancement

  • Replace the AFF "BADFLAG" approach for indicating bad data with a bad sector bitmap.
  • Modify aimage so that it can take a partial disk image and a disk and just image what's missing.
  • Improve the data recovery features of aimage.
  • Replace AFF's current table-of-contents system with one based on B+ Trees.

Timeline Analysis

Write a new timeline viewer that supports:

  • Logfile fusion (with offsets)
  • Logfile correlation
  • View logfiles in the frequency domain.

Carving

JPEG Validator

Create a JPEG decompresser that supports restarts and checkpointing for use in high-speed carving.

Cell Phone Exploitation

Imaging

Develop a tool for imaging the contents of a cell phone memory

Interpretation

  • Develop a tool for reassembling information in a cell phone memory


Corpora Development

Realistic Disk Corpora

There is need for realistic corpora that can be freely redistributed but do not contain any confidential personally identifiable information (PII).

These disk images may be either of an external drive or of a system boot drive. The drive images should have signs of wear --- that is, they should have resident files, deleted files, partially overwritten files, contiguous files, and fragmented files.

From DFRWS 2005 Frank Adelstein (ATC-NY), Yun Gao and Golden G. Richard III (University of New Orleans): Automatically Creating Realistic Targets for Digital Forensics Investigation http://www.dfrws.org/2005/program.shtml

Realistic Network Traffic

Generating realistic network traffic requires constructing a test network and either recording interactions within the network or with an external network.
