Deep forensic artifact analysis after triage — memory dumps (Volatility 3), disk and super-timelines (Plaso), PCAP (tshark), and Windows host artifacts (Zimmerman toolset) — with hashing and chain of custody. Load when an incident moves past first response into "prove what the attacker did on this image": a memory dump to analyze, an E01/disk image, a captured pcap, or Prefetch/Shimcache/Amcache deep-dives. Signals: .dmp/.raw memory image, E01, pcap/pcapng, "analyze this dump", timeline reconstruction, evidence preservation.

# Deep forensic artifact analysis
## When it applies
Triage (`defense-dfir-triage`) has scoped the incident and you now hold preserved evidence —
a memory dump, a disk image (E01/raw), a PCAP, or exported host artifacts — and must prove,
artifact by artifact, what the attacker did: which process ran, what persisted, what left the
network. This is deep analysis of dead-box/dead-disk evidence, not live first response.
## Why it works
Attackers can delete logs, but memory, filesystem metadata ($MFT, USN journal), and packet
captures retain artifacts the attacker never controlled. Parsing them with purpose-built tools
reconstructs execution, persistence, and exfiltration even after the live system was cleaned —
and hashing plus chain of custody makes the conclusions defensible.
