Foremost is an open-source, command-line file carving utility pre-installed on Kali Linux at /usr/bin/foremost, designed for recovering deleted or hidden files from disk images and storage devices. Originally developed by Jesse Kornblum, Kris Kendall, and Nick Mikus for the U.S. Air Force, Foremost uses data carving techniques to identify and extract files based on their headers, footers, and internal structures, bypassing file system metadata. Widely used by digital forensic investigators, incident responders, and ethical hackers, it supports formats like PDF, JPG, MP3, and executable files, making it essential for cyber forensic investigations and data recovery.
