CSIRT-Collect

A set of PowerShell scripts to collect memory and (triage) disk forensics for incident response investigations.

The default script leverages a network share, from which it will access and copy the required executables and subsequently upload the acquired evidence to the same share post-collection.

Permission requirements for said directory will be dependent on the nuances of the environment and what credentials are used for the script execution (interactive vs. automation)

In the demonstration code, a network location of \\Synology\Collections can be seen. This should be changed to reflect the specifics of your environment.

Collections folder needs to include:

• subdirectory KAPE; copy the directory from existing install
• subdirectory MEMORY; 7za.exe command line version of 7zip and Magnet RAM Capture.

• Maps to existing network drive -
• • Subdir 1: “Memory” – Winpmem and 7-Zip executables
• • Subdir 2: ”KAPE” – directory (copied from local install)
• Creates a local directory on asset
• Copies the Memory exe files to local directory
• Captures memory with Magnet RAM Capture
• When complete, ZIPs the memory image
• Renames the zip file based on hostname
• Documents the OS Build Info (no need to determine profile for Volatility)
• Compressed image is copied to network directory and deleted from host after transfer complete
• New temp Directory on asset for KAPE output
• KAPE KapeTriage collection is run using VHDX as output format [$hostname.vhdx]
• VHDX transfers to network
• Removes the local KAPE directory after completion
• Writes a “Process complete” text file to network to signal investigators that collection is ready for analysis

This script will:

• capture a memory image with Magnet Ram Capture,
• capture a triage image with KAPE,
• check for encrypted disks,
• recover the active BitLocker Recovery key, all directly to the USB device.

Prerequisites:

On the root of the USB:

• CSIRT-Collect_USB.ps1
• folder (empty to start) titled 'Collections'
• KAPE folder from default install. Ensure you have EDDv300.exe in \modules\bin\EDD
• MEMORY folder with MRC.exe and 7za.exe inside

Execution:

• Open PowerShell as Adminstrator
• Navigate to the USB device
• Execute ./CSIRT-Collect_USB.ps1
