SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Digital forensics and incident response often involve collecting and analyzing scattered data sources (Windows Event Logs, PCAPs, and filesystem artifacts) to detect intrusions and reconstruct attacks. This Skill provides a cohesive framework to parse, correlate, and interpret evidence across sources for faster and more reliable investigations.

Core Features & Use Cases

  • Windows EVTX parsing and event-id correlation for authentication and privilege escalation.
  • PCAP-based network forensics including NTLM/NTLMv2 patterns, LLMNR/NTLM relay detection, and timeline reconstruction.
  • Filesystem artifact analysis (MFT, NTFS, VSS) and AD attack detection for threat hunting and incident response.

Quick Start

Load a Windows evidence bundle and run the DFIR workflow to automatically parse EVTX, PCAPs, and MFT data.

Frequently Asked Questions about dfir

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate Windows event log analysis for incident response?

Windows event log analysis for incident response is automated by parsing EVTX files and correlating event IDs to detect authentication anomalies and privilege escalation patterns. The Skill structures these workflows to quickly identify security incidents across Windows environments.

What is the best way to reconstruct an attack timeline from PCAP and EVTX files?

Reconstructing an attack timeline from PCAP and EVTX files is achieved through cross-source correlation. The Skill parses network forensics artifacts like NTLM relay patterns alongside Windows event logs to build a cohesive, chronological history of an intrusion.

Can I use this DFIR workflow to analyze NTFS filesystem artifacts like MFT?

Yes, you can use this DFIR workflow to analyze NTFS filesystem artifacts. It supports parsing MFT, NTFS, and Volume Shadow Copies (VSS) to detect Active Directory attacks and extract IOCs during threat hunting investigations.

How does cross-source correlation work during a forensic investigation?

Cross-source correlation during a forensic investigation works by parsing and interpreting evidence from EVTX, PCAP, and filesystem artifacts together. This cohesive framework detects intrusions faster and more reliably than analyzing scattered data sources independently.

Does this incident response Skill detect LLMNR and NTLM relay attacks from network traffic?

Yes, this incident response Skill detects LLMNR and NTLM relay attacks from network traffic. It performs PCAP-based network forensics to identify NTLM/NTLMv2 patterns and reconstruct the timeline of relay attacks.

What do I need to start a digital forensics investigation with this Skill?

To start a digital forensics investigation you need to load a Windows evidence bundle containing EVTX, PCAP, and MFT data. Running the DFIR workflow then automatically parses these sources to detect security incidents.
