Tableau Imager: First Look

We are up against some major hurdles in the digital forensics world that are rapidly changing the way we do business. With 2TB drives on the shelves, the decision to take a full forensic image is no longer obvious. If a user has to be without their computer or a server has to be down for 2 days, that significantly changes the equation. That's why I was excited to see Tableau enter the imaging software space with Tableau Imager (TIM).

Prefetch Parser v1.4 released

I have updated Prefetch Parser. The program was mentioned in Chad Tilbury's blog entry De-mystifying Defrag Identifying When Defrag Has Been Used For Anti-Forensics (Part 1 Windows XP). The main updates to the program are as follows:

  1. Add the Windows 7 option to the drop down box.
  2. GPL all the code (Parse_Prefetch_Info.pl and prefetch_parser_gui.au3)
  3. Make the program parse_prefetch_info callable from the command line (send flag -h or no arguments to get the syntax).
  4. Added reading the Layout.ini file and reporting on all programs/prefetch files that are in the Layout.ini file.
  5. Added a new report that will list the distinct devices/volumes/directories with hyperlinks to
