sleuthkit.org is the official web site for The Sleuth Kit and Autopsy Browser. Both are open source digital investigation tools (a.k.a. digital forensic tools) that run on Windows and Unix systems (such as Linux, OS X, Cygwin, FreeBSD, OpenBSD, and Solaris). They can be used to analyze NTFS, FAT, Ext2, Ext3, UFS1, and UFS2 file systems and several volume system types.
