The Sleuth Kit (TSK) is a collection of UNIX-based command line tools that allow you to investigate a computer. The current focus of the tools is the file and volume systems and TSK supports FAT (12/16/32), Ext2/3, NTFS, UFS (1 & 2), and ISO 9660 file systems.

Autopsy is a frontend for TSK which allows browser-based access to the TSK tools.

Features

The Sleuth Kit is arranged in layers. There is a data layer which is concerned with how information is stored on a disk and a metadata layer which is considered with information such as inodes and directories. The commands that deal with the data layer are prefixed with the letter d, which the commands that deal with the metadata layer are prefixed with the letter i.

Some of the commands in Sleuth Kit are:

dcat
Views the contents of a block.
dls
Lists unallocated blocks. Makes keyword searches more efficient. Gets a list of unallocated blocks.
dcalc
Tells you where an unallocated blocks are.
dstat
Details about a given block.
icat
View contents of a file given its inode value or cluster number. Doesn't list directories, lists the contents.
ils
Lists the files extents on a disk.
istat
Information about an inode number.
