Digital forensics and incident response workflow: read-only evidence acquisition with SHA-256 integrity records, typed acquisition outcomes (collected/cancelled/permission-denied/failed), containment previews with digests and approval receipts, rollback planning before execution, and artifact redaction at collection time. Use when responding to a suspected compromise, acquiring disk/memory/log evidence, planning containment actions with approval gates, or structuring a case file for an incident.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# DFIR — Incident Toolkit Derived from T3MP3ST's `src/dfir/toolkit.ts` (Apache-2.0). Two disciplines make DFIR evidence usable: **read-only acquisition** (never alter what you investigate) and **approved containment** (never change a system without a preview, a digest, and a receipt). ## 1. Acquisition — read-only, verified, typed - Artifacts are collected by read-only collectors; the toolkit NEVER writes to the target during acquisition. - Every artifact becomes an evidence record: `id, caseId, targetId, name, source, collectedAt, receivedAt, sha256, sizeBytes, collector, transfer, verified, redactedMetadata`. - Integrity: hash at collection, re-verify on receipt (`verified` flag). A mismatch is a finding about your own pipeline. - Duplicate names within one acquisition are rejected — silent dedup loses evidence. - Metadata is redacted at acquisition (`redactedMetadata`), not at report time. - Outcomes are typed and final: `collected | cancelled | permission-denied | collection-failed`. `permission-denied` is a real result (record it, move on); it is not a retry candidate. ## 2. Containment — preview, digest, approval, receipt …

How to install
mdr add miosa-osa/osa/dfir-incident-toolkit@sha256:93cc3283314c18aeThe line at the top of this page pins the label git:20260913.e13b6b8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
