The Foremost Open Source Forensic Tool

By Ray Strubinger, August 06, 2003

Several open source forensic tools have been created for the Unix platform; most notably, The Coroner's Toolkit (TCT) by Dan Farmer and Wietse Venema, as well as The @stake Sleuth Kit (TASK) and its browser-based front end, Autopsy, both created by Brian Carrier. While TCT and TASK/Autopsy have been written about frequently, there is another very useful application known as "foremost" that has received relatively little attention outside of a few computer forensics mailing lists.
