Plaso vs Tsurugi Linux

Plaso is a Python-based engine for creating timelines used in digital forensic analysis. Its log2timeline tool extracts events from files, directories, storage-media images, or devices and stores them in a Plaso storage file. The psort tool can filter and sort that data and run automatic analysis. Other command-line tools include image_export, pinfo, and psteal. Documented inputs include Windows event logs and registry data, browser histories, SQLite databases, text logs, and cloud audit logs from AWS CloudTrail, Azure Activity, Google Cloud, and Microsoft 365. Plaso can create a CSV timeline from a storage image using psteal with dynamic output; listed formats also include JSON, JSON Lines, KML, TLN, XLSX, OpenSearch, and Timesketch. The framework supports additional parsers, analysis plug-ins, and scripts for forensic tasks. Documented analysis plug-ins include VirusTotal, NSRL server, and hash tagging. Plaso is free, with no commercial plan or usage limits stated. The project recommends packaged releases for general use and a version no older than six months.

Tsurugi Linux is a free Linux distribution for digital forensics, incident response, malware analysis, and OSINT. Its 64-bit [LAB] edition is based on Ubuntu 24.04.3 LTS with a custom kernel based on version 6.19.10, including kernel-level device write blocking. It also provides a Computer Vision analysis section and an OSINT profile switcher. The system can run live, although the project’s primary aim is an installed forensics lab. Tsurugi Acquire is a separate lightweight 32-bit live edition for booting a computer and acquiring mass-storage devices. The related Bento toolkit contains over 300 applications for live forensics and incident response on Windows, Linux, and macOS. The project recommends checking image hashes and verifying signatures with its PGP public key. [LAB] updates come from official Ubuntu repositories, but the FAQ warns that dist-upgrade can break the operating system. Tsurugi Linux [LAB] and Tsurugi Acquire are free under the GNU General Public License and supplied without warranty; some included tools are not open source. Evidence work can cover disks, volatile memory, mobile devices, file systems, OS artifacts, and cloud sources.
