Review: Coroner's Toolkit
The Coroner’s Toolkit, or TCT is an open-source set of forensic tools for performing post-mortem analysis on Unix systems. Written by Dan Farmer and Wietse Venema, both very well known in security circles for such programs as SATAN, TCT is not an easy product to use. A serious knowledge of Unix is a prerequisite for success, but if you can manage it, this is an extremely powerful set of tools.
