Forensicator: Powershell Script for Incidence Response and Live Forensics

Live Forensicator is part of the Black Widow Toolbox, its aim is to assist Forensic Investigators and Incidence responders in carrying out a quick live forensic investigation.

It achieves this by gathering different system information for further review for anomalous behaviour or unexpected data entry, it also looks out for unusual files or activities and points it out to the investigator.

It is paramount to note that this script has no inbuilt intelligence its left for the investigator to analyse the output and decide on a conclusion or decide on carrying out more deeper investigation.

Optional Dependencies

This script is written in powershell for use on windows PCs and Servers.

For additional features it depends on external binaries.

It has a supporting file WINPMEM for taking RAM dumps.

It also depends on Nirsoft’s BrowserHistoryView for exporting browser history.

This script is expected to work out of the box.

winpmem_mini_x64_rc2.exe | BrowsingHistoryView64.exe | BrowsingHistoryView86.exe | etl2pcapng64.exe | etl2pcapng86.exe

Usage and Examples

Copy the files to the computer:

git clone https://github.com/Johnng007/Live-Forensicator.git

Execution:

.\Forensicator.ps1 <parameters>

• Basic Usage

.\Forensicator.ps1

• Check for Version

.\Forensicator.ps1 -Version

• Check for Updates

.\Forensicator.ps1 -Update

• Extract Event Logs alongside Basic Usage

.\Forensicator.ps1 -EVTX EVTX

• Grab weblogs IIS & Apache

.\Forensicator.ps1 -WEBLOGS WEBLOGS

• Run Network Tracing & Capture PCAPNG

.\Forensicator.ps1 -PCAP PCAP

• Extract RAM Dump alongside Basic Usage

.\Forensicator.ps1 -RAM RAM

• Check for log4j with the JNDILookup.class

.\Forensicator.ps1 -log4j log4j

• Yes of course you can do all

.\Forensicator.ps1 -EVTX EVTX -RAM RAM -log4j log4j

• For Unattended Mode on Basic Usage

.\Forensicator.ps1 -OPERATOR "Ebuka John" -CASE 01123 -TITLE "Ransomeware Infected Laptop" -LOCATION Nigeria -DEVICE AZUZ

• You can use unattended mode for each of the other parameters

.\Forensicator.ps1 -OPERATOR "Ebuka John" -CASE 01123 -TITLE "Ransomeware Infected Laptop" -LOCATION Nigeria -DEVICE AZUZ -EVTX EVTX -RAM RAM -log4j log4j

• Check for files that has similar extensions with ransomware encrypted files (can take some time to complete)

.\Forensicator.ps1 -RANSOMEWARE RANSOMWARE

• You can compress the Forensicator output immidiately after execution Oneliner

.\Forensicator.ps1 ; Start-Sleep -s 15 ; Compress-Archive -Path "$env:computername" -DestinationPath "C:\inetpub\wwwroot\$env:computername.zip" -Force

You can find all extracted Artifacts in the script’s working directory.

Forensicator Has the ability to Search through all the folders within a system looking for files with similar extensions as well known Ransomwares, Albeit this search takes long but its helpful if the Alert you recieved is related to a Ransomware attack, Use the -RANSOMWARE Parameter to invoke this.

Forensictor now hs the ability to capture network traffic using netsh trace, this is useful when your investigation has to do with asset communicating with known malicious IPs, this way you can parse the pcapng file to wireshark and examine for C&C servers. By Defult i set the capture to take 120secs
