'''THE FARMER'S BOOT CD''' ('''FBCD''') is a [[Linux]] [[boot CD]] developed by [[Thomas Rude]] ('farmerdude').
+
=Programming Projects=
  
Taking a different approach than other [[Live CDs]], this CD was designed and optimized for previewing systems before acquiring. It contains a number of programs forensic practitioners can utilize to preview both [[Windows]] and [[Linux]] systems in a [[forensically sound]] manner.
+
==Small-Sized Programming Projects==
 +
* Modify [[bulk_extractor]] so that it can directly acquire a raw device under Windows. This requires replacing the current ''open'' function call with a ''CreateFile'' function call and using windows file handles.
 +
* Rewrite SleuthKit '''sorter''' in C++ to make it faster and more flexible.
  
== Preview Capabilities ==
+
==Medium-Sized Programming Projects==
 +
* Create a program that visualizes the contents of a file, sort of like hexedit, but with other features:
 +
** Automatically pull out the strings
 +
** Show histogram
 +
** Detect crypto and/or stenography.
 +
* Extend [[fiwalk]] to report the NTFS alternative data streams.
 +
* Create a method to detect NTFS-compressed cluster blocks on a disk (RAW data stream). A method could be to write a generic signature to detect the beginning of NTFS-compressed file segments on a disk. This method is useful in carving and scanning for textual strings.
 +
* Write a FUSE-based mounter for SleuthKit, so that disk images can be forensically mounted using TSK.
 +
* Modify SleuthKit's API so that the physical location on disk of compressed files can be learned.
  
THE FARMER'S BOOT CD has been designed for previewing both Windows and Linux systems. On-site previews before acquisitions is an emerging trend in the U.S.A. due to legal and technological reasons.
 
  
Below is a short list of what can be accomplished in a simple GUI on this CD;
+
==Big Programming Projects==
 +
* Develop a new carver with a plug-in architecture and support for fragment reassembly carving (see [[Carver 2.0 Planning Page]]).
 +
* Write a new timeline viewer that supports Logfile fusion (with offsets) and provides the ability to view the logfile in the frequency domain.
  
* Mount file systems read-only, including journalled file system types
+
* Correlation Engine:
* Obtain a list of deleted files for ext2, FAT12/16/32, and NTFS file system types
+
** Logfile correlation
* Undelete deleted files from NTFS file systems
+
** Document identity identification
* Obtain both E-mail and URL addresses from the Windows "pagefile.sys" file
+
** Correlation between stored data and intercept data
* Read the Recycle Bin INFO2 records
+
** Online Social Network Analysis
* Read Windows event log files (AppEvent.Evt, SecEvent.Evt, SysEvent.Evt)
+
* Read many log files from Linux systems (shell histories, system logs, security logs, accounting logs, etc.)
+
* Obtain file system metainformation (creation date, last mount and write date, version, label, UUID, etc.)
+
* Parse Internet cache files from IE, Mozilla, and Opera, pulling cookies and histories
+
* Catalog target file system, selecting files of interest by extension or header
+
* Convert date/time between UNIX 32bit, UNIX hex, human readable, Windows 64bit, and Windows hex
+
* Generate thumbnails for all graphics in fully qualified path filename
+
* Obtain drive information (serial number, make/model, firmware, HPA status, etc.)
+
* Obtain system BIOS table information (serial numbers, dates, UUIDs, etc.)
+
* Obtain system hardware catalog
+
* Double-clicking on most common file types opens them (Documents, Graphics, Presentations, Movies, Audio, etc.)
+
  
== External Links ==
+
* Find and download in a forensically secure manner all of the information in a social network (e.g. Facebook, LinkedIn, etc.) associated with a targeted individual.
 +
** Determine who is searching for a targeted individual. This might be done with a honeypot, or documents with a tracking device in them, or some kind of covert Facebook App.
 +
** Automated grouping/annotation of low-level events, e.g. access-time, log-file entry, to higher-level events, e.g. program start, login

Interested in doing research in computer forensics? Looking for a master's topic, or just some ideas for a research paper? Here is our list. Please feel free to add your own ideas.

Many of these would make a nice master's project.

Timeline analysis

  • Mapping differences and similarities in multiple versions of a system, e.g. those created by Windows Shadow Volumes

These are research areas that could easily grow into a PhD thesis.

  • General-purpose detection of:
    • Stegnography
    • Sanitization attempts
    • Evidence Falsification (perhaps through inconsistency in file system allocations, application data allocation, and log file analysis.
  • Visualization of data/information in digital forensic context
