Backtrack4 on USB (on Windows)

-

A simple way to install Backtrack 4 on a USB stick is to use UNetBootin. UNetbootin can be used to create live (i.e., bootable images with a fully functional OS on it) USB images. This is the first time I tried this route and it seems to work alright.
Otherwise, if you are the linux fans, our good old friend dd does a great job.

dd if=bt4-final.iso of=/dev/sda bs=4096 conv=noerror,sync

Bit of Forensics

-

I like using dcfldd for creating the raw images, because it shows a nice status…it’s interesting to see progress.

dcfldd if=/dev/sda of=/mnt/sdb1/filename.dd hash=md5 md5log=hashfile.md5 conv=noerror,sync bs=4096

It’s the ‘bs’ (stands for bytesize) that makes the difference (…always does doesn’t it ;-).

Autopsy – The forensics browser always uses the ~/.autopsy as the base directory for storing the files from the cases. The following command is helpful in changing the directory in which the cases should be stored:

./autopsy -d /mountpoint/dirname

The exiftool is a cool application that can read meta-information to determine the different types of files.
