When to Use

• When investigating security incidents on Windows systems through event log analysis
• For detecting lateral movement, privilege escalation, and persistence mechanisms

• Chainsaw, Hayabusa, or EvtxECmd for parsing and detection
• Sigma rules for automated threat detection
• Understanding of critical Windows Event IDs
• Python with python-evtx or evtx library for custom parsing
• PowerShell for live system analysis (if applicable)

Workflow

Step 1: Collect Windows Event Log Files

# Extract EVTX files from forensic image
mount -o ro,loop,offset=$((2048*512)) /cases/case-2024-001/images/evidence.dd /mnt/evidence

mkdir -p /cases/case-2024-001/evtx/
cp /mnt/evidence/Windows/System32/winevt/Logs/*.evtx /cases/case-2024-001/evtx/
