Syntax
=====
Use these commands to rip registry hives.
C:\tools\RegRipper\rip.exe –r c:\cases\customerX\registry\SAM –f SAM > c:\cases\ripped\systemY_sam_ripped.txt
C:\tools\RegRipper\rip.exe –r c:\cases\customerX\registry\system –f System> c:\cases\ripped\systemY_system_ripped.txt
C:\tools\RegRipper\rip.exe –r c:\cases\customerX\registry\ntuser.dat –f ntuser> c:\cases\ripped\systemY_ntuser.dat.userX_ripped.txt
Use these commands to create a bodyfile and timeline. If you want a more detailed explanation of how to generate timelines, read my blog posts about timeline creation.
C:\tools\TSK\fls –m ‘C:/’ –f ntfs –r \\.\F: > c:\cases\customerX\timelines\systemY_bodyfile
Perl C:\tools\TSK\mactime.pl –d –b C:\cases\customerX\timelines\systemY_bodyfile\systemY_timeline.csv
You can add logs to your bodyfile with Log2Timeline
C:\>Perl C:\Perl\bin\Log2timeline –t
You can hives and NTUSER.dat files to your bodyfile with regtime
C:\>Perl C:\tools\bin\regtime.pl –m HKLM/system –r c:\cases\customerX\hives\system >> \c:\cases\customerX\timelines\systemY_bodyfile
Search for suspect keywords
C:\cases\customerX\ripped>strings *.txt | grep –i
C:\cases\customerX\timeline>strings *.csv | grep –i
Search for suspect timeframe
C:\cases\customerX\ripped>strings *.txt | grep –i
C:\cases\customerX\timeline>strings *.csv | grep –i
Know how to stack your searches! CRITICAL!!!

Thanks for using Memoryze and Audit Viewer. Have you played with the latest version of Memoryze (1.4.2900)? Also, I am interested in hearing about any experiences using Memoryze in conjunction with F-response. If you setup Memoryze to run against the drive/file/device F-response exposes as the remote machine's memory, Memoryze should execute just as if you were running against a memory image (use the "memory file" parameter).
ReplyDeleteThanks,
Jamie
I wish I could have been there. I like the idea of the targeted approach and would love to have seen the presentation. Any idea if a recording was made and will be available?

Hey there Chris. Great article and well put together. One thing I what to echo is that I belive the use of non-commercial tools actually helps in analysis capability and adds to agility.
ReplyDeleteI recently gave a talk in Silicon Valley and an anonomous evaluation submitter actually wrote in effect "...its impossible to be effiecient if your digital forensics is done without commercial tools." I did not get a name nor was the argument supported so this is all I had to go on in respect to feedback. (The other posters that evaluated the talk were largely postive.)
My guess is this was an attempt to argue against open-source projects and non-commercially developed tools like Volatility and Brian Carrier's TSK, and Harlan's Reg Ripper. I still belive the best analysis engine out there is actually located between an analyst's ears and it is up to them to executre appropriate tool-selection that enables them to analyze the information and come to correct solutions. This is not restricted only to the realm of flashy, well-funded commercial software IMHO.
