## プロジェクトの歴史と使われ方

Chainsaw is a WithSecure Labs command-line tool for rapid Windows forensic triage. It searches event logs and other Windows artefacts, applies Sigma and custom detection rules, and emits investigator-friendly output formats.

### プロジェクトの歴史

WithSecure Countercept created Chainsaw for incident-response cases where endpoint telemetry or a SIEM was not available, so analysts needed fast standalone processing of Windows artefacts. The public GitHub repository was created in August 2021 and v1.0.0 was released later that month.

The project evolved from an all-in-one threat-hunting bundle toward a tool that expects users to keep Sigma rules and sample event logs separately. The README notes that Chainsaw v2 stopped including Sigma Rules and EVTX-Attack-Samples as submodules so users could track those projects independently.

### 採用の歴史

Chainsaw is distributed through GitHub releases, Nix, and the Homebrew formula named chainsaw. That packaging path matters because the tool is useful as a portable first-response binary on analyst workstations and ephemeral response systems.

GitHub release metadata shows active maintenance from v1.0.0 in 2021 through v2 releases in 2026.

### 使われ方

Typical use is to run chainsaw against Windows event-log collections, optionally supplying a Sigma rules directory and a mapping file such as mappings/sigma-event-logs-all.yml. The README documents output formats including table, CSV, and JSON, plus timeline generation from Shimcache enriched with Amcache data.

### パッケージ好きにとっての重要性

Chainsaw is notable in package-manager culture because it packages modern Rust DFIR tooling for a workflow that often used heavier SIEM stacks such as Splunk or ELK. It also shows the Sigma ecosystem becoming something local CLIs can consume directly.

### タイムライン

- 2021: GitHub repository created by WithSecureLabs.
- 2021: v1.0.0 published on GitHub releases.
- 2023: v2 line documented removal of bundled Sigma and EVTX sample submodules.
- 2026: v2.16.0 published on GitHub releases.

### Related projects

- SigmaHQ/sigma provides the Sigma detection rules Chainsaw can run.
- omerbenamram/evtx is the Rust EVTX parser wrapped by Chainsaw.
- sbousseaden/EVTX-ATTACK-SAMPLES is used in the README example dataset workflow.
