Forensicator – Powershell Script To Aid Live Forensics & Incidence Response

Forensicator

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 behavior or unexpected data entry, it also looks out for unusual files or activities and points them 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 a 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 https://github.com/Velocidex/WinPmem

It also depends on Nirsoft’s BrowserHistoryView for exporting browser history http://www.nirsoft.net/utils/browsing_history_view.html

This script is expected to work out of the box.

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

# copy the files to the computer
git clone https://github.com/Johnng007/Live-Forensicator.git

# Execution
.\Forensicator.ps1 <parameters>

Examples

# Basic
.\Forensicator.ps1

# Check your Version
.\Forensicator.ps1 -Version

# Check for Updates
.\Forensicator.ps1 -Update

# Decrypt An Encrypted Artifact
.\Forensicator.ps1 -DECRYPT DECRYPT

# Extract Event Logs alongside Basic Usage
.\Forensicator.ps1 -EVTX EVTX

#Grab weblogs IIS & Apache
.\Forensicator.ps1 -WEBLOGS WEBLOGS

#Run Network Tracing & Capture PCAPNG for 120 secounds
.\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

# Encrypt Artifact after collecting it
.\Forensicator.ps1 -ENCRYPTED ENCRYPTED

# Yes of course you can do all
.\Forensicator.ps1 -EVTX EVTX -RAM RAM -log4j log4j -PCAP PCAP -WEBLOGS WEBLOGS

# For Unattended Mode on Basic Usage
.\Forensicator.ps1 -OPERATOR "Ebuka John" -CASE 01123 -TITLE "Ransomware 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 "Ransomware 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 -RANSOMWARE 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

Notes

Run the script as an administrator to get value.
The results are output in nice-looking HTML files with an index file.
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 Ransomware, Albeit this search takes long but it’s helpful if the Alert you received 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 assets communicating with known malicious IPs, this way you can parse the pcapng file to wireshark and examine for C&C servers. By Default I set the capture to take 120secs

Sometimes it may be paramount to maintain the integrity of the Artifacts, where lawyers may argue that it might have been compromised on transit to your lab. Forensicator can now encrypt the Artifact with a unique randomly generated key using AES algorithm, you can specify this by using the -ENCRYPTED parameter. You can decrypt it at will anywhere anytime even with another copy of Forensicator, just keep your key safe. This task is performed by the FileCryptography.psm1 file
