name	forensics-triage
description	Digital forensics and incident response triage skill for disk, memory, network, cloud, and endpoint artifacts. Covers Volatility 3, Velociraptor, KAPE, Plaso, Autopsy, Chainsaw, Hayabusa, Zeek, Arkime, EVTX, AWS/Azure/GCP audit logs, and timeline reconstruction. Use to extract IOCs, build incident timelines, and produce defensible analyst reports.

Forensics Triage

Operating Rules

• Preserve chain of custody: hash before and after handling; record acquisition method, examiner, and timezone (UTC preferred).
• Work on copies; mount images read-only; document every tool, version, and flag.
• Separate observation (what the artifact says) from inference (what likely happened).

Triage Workflow

1. Collect: KAPE targets, velociraptor artifacts, memory via winpmem/avml, cloud logs via provider exports.
2. Parse: plaso/log2timeline for super-timeline; chainsaw/hayabusa for Windows EVTX; volatility3 for RAM; bulk_extractor for carving.
3. Reconstruct timeline: anchor on initial access, then enumerate execution, persistence, lateral movement, collection, exfil, impact.
4. Extract IOCs: hashes, domains, IPs, mutexes, registry keys, scheduled tasks, services, cron, browser artifacts, cloud principals.
5. Correlate: cross-host, cross-cloud, identity-tier; build a narrative with ATT&CK mapping.
6. Report: timeline, scope, dwell time, attribution confidence, recommendations.

Cloud and Identity Focus

• AWS: CloudTrail, GuardDuty, IAM Access Analyzer, Athena queries; assume-role chains.
• Azure: AAD sign-in/audit, MCAS, Defender; OAuth consent abuse.
• GCP: Cloud Audit, Workspace Login; service account key misuse.
• Identity: token theft, primary refresh token abuse, federation trust manipulation.

Output Contract

• chain-of-custody.md, acquisition.log.
• timeline.csv super-timeline with annotations.
• iocs.stix.json, findings.md per host/account.
• report.md: executive narrative, root cause, dwell time, scope, recovery steps, lessons learned.
