The Sleuth Kit (TSK) is an open-source collection of command-line digital forensics tools, pre-installed on Kali Linux at /usr/bin/, designed for analyzing disk images and file systems to recover evidence in cyber investigations. Developed by Brian Carrier, TSK supports file systems like NTFS, FAT, EXT2/3/4, UFS, and HFS+, enabling forensic analysts, incident responders, and ethical hackers to examine deleted files, partition structures, and timelines. Often paired with Autopsy’s GUI, TSK’s modular utilities provide granular control for advanced forensic tasks.
