# Digital Forensics & IR Artifacts

## ACTION REQUIRED (execute immediately after reading)

1. `NOW`: read `../field-journal/precedent-pentest.md` or the organization's IR authorization statement
2. `NOW`: confirm this is **forensics/traceback**, not offensive scanning
3. `NOW`: set up a case; read-only copies of evidence first (write-protect original media)
4. `NEXT`: tool-index; Volatility etc. are often manual
5. `ACT`: preservation hashes → timeline → key artifacts

## Applicable Scenarios

- Memory dump analysis (Volatility 2/3)
- Disk / E01 / dropped-file timelines
- PCAP traceback and protocol recovery (can combine with `protocol-reverse/`)
- Host artifacts: Prefetch, Shimcache, Event Log, browser history
- IR IOC extraction (combined with `malware-analysis/` / `threat-hunting/`)

## Workflow

### 1. Preservation

```text
□ Compute SHA256; record timezone and acquisition commands
□ Work on copies; originals read-only
□ Note chain of custody into the timeline
```

### 2. Memory

```bash
vol -f mem.dmp windows.info
vol -f mem.dmp windows.pslist
vol -f mem.dmp windows.netscan
vol -f mem.dmp windows.cmdline
```

### 3. Host Artifacts

```text
□ Event logs: Security / PowerShell / Sysmon
□ Persistence: Run keys, services, scheduled tasks, WMI
□ Execution traces: Amcache, Prefetch, BAM
```

### 4. Network

```text
□ tshark session and DNS statistics
□ Export suspicious streams → protocol-reverse or malware C2 analysis
```

## Toolchain

| Tool | Purpose |
|------|------|
| Volatility 3 | Memory |
| Timeline Explorer / Plaso | Super timelines |
| tshark | PCAP |
| Eric Zimmerman toolset | Windows artifacts |
| Autopsy / FTK Imager | Disks |

## Routing Context

**Upstream**: MASTER R25  
**Downstream**: deep digging into malicious samples → malware-analysis; rules → threat-hunting

## Task Completion Self-Check

- [ ] Preservation hashes and copy policy in place?
- [ ] Timeline independently reviewable?
- [ ] IOCs sanitized and classified?
- [ ] Checklist?
