Windows EVTX Export for Hayabusa

This document defines the Windows-side export path for Hayabusa DFIR enrichment.

Purpose

Windows hosts do not analyze EVTX locally for this contour.

They export selected event logs into a bounded forensic staging area, and the server-side Hayabusa workflow on 10.10.10.13 analyzes those artifacts later.

Export script

• script: windows/export-evtx-for-hayabusa.ps1
• deployed path on Windows host:
  • <StateRoot>\export-evtx-for-hayabusa.ps1

Default config path:

• C:\ProgramData\AWatch-rus\deployment-config.json

Default export root

• <StateRoot>\forensics\evtx-exports
• Ansible override variable: aw_windows_forensics_root
• retention override variable: aw_windows_evtx_retention_days
• channel override variable: aw_windows_evtx_channels

Example:

• C:\ProgramData\AWatch-rus\forensics\evtx-exports

Each run creates:

• <forensics-root>\<HOST>-<YYYYMMDD-HHMMSS>\evtx\*.evtx
• <forensics-root>\<HOST>-<YYYYMMDD-HHMMSS>\manifest.json
• optional zip:
  • <forensics-root>\<HOST>-<YYYYMMDD-HHMMSS>.zip

Default channel set

• Security
• System
• Application
• Microsoft-Windows-PowerShell/Operational
• Microsoft-Windows-TerminalServices-LocalSessionManager/Operational
• Microsoft-Windows-TerminalServices-RemoteConnectionManager/Operational

Notes:

• Sysmon is intentionally not assumed by default.
• If Sysmon exists in the environment, it should be added later as an explicit extension.
• the channel list is now carried through deployment config and validation, not left as an implicit script default.

Retention

• default retention: 14 days
• cleanup is local to the forensic export root
• old export directories and zip packages are removed after the retention cutoff
• retention is now exposed as aw_windows_evtx_retention_days in Ansible vars

Example run

powershell.exe -ExecutionPolicy Bypass -File C:\ProgramData\AWatch-rus\export-evtx-for-hayabusa.ps1

Example with custom window:

powershell.exe -ExecutionPolicy Bypass -File C:\ProgramData\AWatch-rus\export-evtx-for-hayabusa.ps1 -DaysBack 1

Boundaries

• output stays outside standard AW buckets
• output stays outside normal DLP screenshot artifacts
• this phase only defines and validates Windows export
• transfer to 10.10.10.13 and Hayabusa execution belong to later phases
