Incident Response & Digital Forensics

Purpose

Enable Claude to assist with structured incident response operations following NIST SP 800-61 and the SANS PICERL framework. Claude generates IR playbooks, guides evidence collection with chain of custody, constructs forensic timelines, interprets memory forensics output, and produces post-incident reports.

Activation Triggers

This skill activates when the user asks about:

Creating an incident response playbook (ransomware, phishing, breach, etc.)
Evidence collection and chain of custody procedures
Forensic timeline construction from logs or artifacts
Memory forensics using Volatility
Post-incident report generation
DFIR (Digital Forensics and Incident Response) procedures
Containment and eradication strategies
Root cause analysis for security incidents
IR metrics, SLA tracking, or reporting for management

Prerequisites

pip install pyyaml jinja2 pandas python-dateutil

Recommended DFIR tools:

Volatility 3 — Memory forensics framework
Autopsy / Sleuth Kit — Disk forensics
plaso / log2timeline — Supertimeline generation
KAPE — Evidence collection (Windows)
Velociraptor — Enterprise-scale endpoint forensics
FTK Imager — Forensic imaging (Windows)
dd / dcfldd / dc3dd — Disk imaging (Linux)

PICERL Framework Overview

Every IR engagement follows the PICERL lifecycle:

Phase	Key Actions	Skill Outputs
Preparation	Verify tools, comms, access	Readiness checklist
Identification	Confirm incident, scope, severity	Incident classification
Containment	Isolate systems, stop spread	Containment actions list
Eradication	Remove threat, close access	Eradication checklist
Recovery	Restore systems, verify integrity	Recovery runbook
Lessons Learned	Post-incident review	IR report + improvements

Core Capabilities

1. IR Playbook Creation

When the user asks to create a playbook for a specific incident type:

Claude generates detailed, role-assigned playbooks in this structure:

Ransomware Response Playbook (Example):

# IR Playbook: Ransomware Attack
Version: 2.0 | Owner: SOC Manager | Review: Quarterly

## Trigger Conditions
- Multiple encrypted files discovered (ransom extension detected)
- Ransom note found on file shares or desktop
- EDR alert for mass file modification activity
- User reports files inaccessible with unfamiliar extensions

## Severity Classification
- CRITICAL: Domain controller / backup infrastructure affected
- HIGH: Production servers / business-critical data affected
- MEDIUM: Isolated workstation, contained environment

---

## Phase 1: Identification (Target: 15 minutes)
**IR Lead:**
- [ ] Confirm incident is ransomware (verify encrypted files + ransom note)
- [ ] Determine initial infection vector (phishing? RDP? Supply chain?)
- [ ] Identify Patient Zero — first encrypted system
- [ ] Assess scope: How many systems? Which business units?
- [ ] Declare incident severity and notify stakeholders
- [ ] Open incident ticket and begin documentation

**Forensics:**
- [ ] DO NOT REBOOT infected systems (preserve volatile evidence)
- [ ] Capture memory dump: `winpmem_mini_x64_rc2.exe output.raw`
- [ ] Collect running processes: `tasklist /v > processes.txt`
- [ ] Collect network connections: `netstat -ano > netstat.txt`

## Phase 2: Containment (Target: 30 minutes)
**Network Team:**
- [ ] Isolate affected systems (pull network cable or quarantine in VLAN)
- [ ] Block identified C2 IPs/domains at perimeter firewall
- [ ] Disable RDP externally if RDP was the initial vector
- [ ] Preserve network capture if encryption is still occurring

**Active Directory:**
- [ ] Identify all accounts used by the ransomware (service accounts, domain accounts)
- [ ] Reset passwords for all potentially compromised accounts
- [ ] Revoke active sessions for affected accounts
- [ ] Check for newly created privileged accounts

## Phase 3: Eradication
- [ ] Identify all persistence mechanisms (registry, services, scheduled tasks)
- [ ] Remove all malicious artifacts
- [ ] Verify no backdoors remain (check with Autoruns, process scanning)
- [ ] Patch the exploited vulnerability if one was used

## Phase 4: Recovery
- [ ] Restore from clean backup (verified pre-infection)
- [ ] Validate backup integrity before restoration
- [ ] Rebuild from gold image if backup compromised
- [ ] Verify data integrity after restoration
- [ ] Phased return to production

## Phase 5: Lessons Learned (Within 2 weeks)
- [ ] Full incident timeline documented
- [ ] Root cause identified and remediated
- [ ] Detection gaps addressed
- [ ] CSOC playbook updated
- [ ] Management report delivered

Other supported playbook types:

Phishing Campaign Response
Data Breach / Exfiltration
Business Email Compromise (BEC)
Insider Threat
DDoS Attack
Account Compromise / Credential Stuffing
Supply Chain Compromise
Cloud Misconfiguration / Breach

2. Evidence Collection & Chain of Custody

When the user asks to collect forensic evidence:

Order of Volatility (most volatile → least volatile):

1. CPU registers and cache
2. Routing tables, ARP cache, process table
3. Memory (RAM) — ALWAYS capture first
4. Temporary file systems, swap space
5. Running processes and open files
6. Network connections and open ports
7. Disk images
8. Log files (local + remote SIEM)
9. Physical media

Evidence Collection Commands:

# Windows — Live acquisition
winpmem_mini_x64_rc2.exe memory.raw              # Memory dump
tasklist /svc > processes.txt                     # Running processes
netstat -ano > connections.txt                    # Network connections
wmic process get caption,processid,parentprocessid,commandline > process_full.txt
reg export HKLM reg_hklm.reg                     # Registry
dir /s /a "C:\Users\*\AppData\Roaming\*" > appdata.txt

# Linux — Live acquisition
sudo avml /tmp/memory.lime                        # Memory dump (avml)
ps auxf > processes.txt                           # Process tree
netstat -tulnap > connections.txt                 # Network connections
cat /proc/*/cmdline | strings > process_cmdlines.txt
ls -la /tmp/ /var/tmp/ /dev/shm/ > temp_dirs.txt
crontab -l -u root > crontabs.txt
find / -mtime -7 -type f > recently_modified.txt  # Modified in last 7 days

Chain of Custody Template:

## Evidence Chain of Custody Form

| Field | Value |
|-------|-------|
| Evidence ID | IR-2025-001-E01 |
| Incident ID | IR-2025-001 |
| Description | Memory dump from HOSTNAME (192.168.1.100) |
| Collected by | [Analyst Name] |
| Collection time | 2025-05-28 14:30 UTC |
| Collection method | winpmem_mini_x64_rc2.exe |
| MD5 hash | [hash of evidence file] |
| SHA256 hash | [hash of evidence file] |
| Storage location | \nas\ir\IR-2025-001\evidence\ |
| Chain of custody | Analyst → Evidence Locker → Lab |

**Access Log:**
| Date/Time | Person | Purpose | Signature |
|-----------|--------|---------|-----------|
| 2025-05-28 14:30 | [Analyst] | Initial collection | [Sig] |

3. Forensic Timeline Analysis

When the user asks to build an incident timeline:

Collect timestamps from all available sources:
- Windows Event Logs (Security, System, Application, PowerShell)
- Web server access logs
- Firewall / proxy logs
- Email server logs (delivery, read receipts)
- File system timestamps (Modified, Accessed, Changed, Born)
- Registry LastWrite timestamps
- Prefetch timestamps (evidence of execution)
Normalize to UTC — Confirm system timezone before conversion

Generate supertimeline:

python scripts/timeline_builder.py --logs ./collected_logs/ --output timeline.csv
python scripts/timeline_builder.py --logs ./logs/ --format html --start "2025-05-20" --end "2025-05-28"

Identify the kill chain progression:

## Incident Timeline — [Incident ID]

[T-72h] 2025-05-25 09:15 UTC — DELIVERY
  Phishing email received: "Invoice_May2025.pdf.exe" from spoofed sender
  Mail log: SMTP delivery to user@victim.com from 185.x.x.x

[T-48h] 2025-05-26 14:22 UTC — EXECUTION
  User executed attachment: Event 4688 (process creation)
  Parent: outlook.exe → Child: powershell.exe -enc [base64]

[T-48h] 2025-05-26 14:22 UTC — C2 ESTABLISHED
  Outbound connection: 203.x.x.x:443 (beacon_interval: 60s)
  DNS query: malicious-c2.evil.com → 203.x.x.x

[T-24h] 2025-05-27 02:00 UTC — LATERAL MOVEMENT
  PsExec from WORKSTATION01 to SERVER02 (admin$)
  Event 4624 (login type 3) on SERVER02 from WORKSTATION01

[T-2h]  2025-05-27 12:30 UTC — DATA EXFILTRATION
  Large POST request (450MB) to dropbox-like service

[T-0h]  2025-05-28 14:00 UTC — DETECTION
  SOC analyst detected anomalous outbound transfer

4. Memory Forensics

When the user shares Volatility output or asks about memory forensics:

Essential Volatility 3 Commands:

# Process listing
python vol.py -f memory.raw windows.pslist
python vol.py -f memory.raw windows.pstree           # Show parent-child
python vol.py -f memory.raw windows.psscan           # Find hidden processes
