Introduction MemProcFS and Memory Forensics

Check out Super Easy Memory Forensics by Hiroshi Suzuki and Hisao Nashiwa.

Prerequisites

1. Download and install the latest Dokany Library Bundle → DokanSetup.exe
   https://github.com/dokan-dev/dokany/releases/latest

2. Download and install the latest .NET 6 Desktop Runtime (Requirement for EZTools)
   https://dotnet.microsoft.com/en-us/download/dotnet/6.0

3. Download and install the latest Windows package of ClamAV → .msi
   https://www.clamav.net/downloads#otherversions

4. First Time Set-Up of ClamAV
   Launch Windows PowerShell console as Administrator.
   cd "C:\Program Files\ClamAV"
copy .\conf_examples\freshclam.conf.sample .\freshclam.conf
copy .\conf_examples\clamd.conf.sample .\clamd.conf
write.exe .\freshclam.conf → Comment or remove the line that says "Example".
   write.exe .\clamd.conf → Comment or remove the line that says "Example".
   https://docs.clamav.net/manual/Usage/Configuration.html#windows

5. Optimize ClamAV scan speed performance (30% faster)
   Open "C:\Program Files\ClamAV\clamd.conf" with your text editor and search for: "Don't scan files and directories matching regex"
   ExcludePath "\\heaps\\"
ExcludePath "\\handles\\"
ExcludePath "\\memmap\\vad-v\\"
ExcludePath "\\sys\\pool\\"

6. Create your free IPinfo account [approx. 1-2 min]
   https://ipinfo.io/signup?ref=cli
   Open "MemProcFS-Analyzer.ps1" with your text editor, search for "Please insert your Access Token here" and copy/paste your access token.

7. Install the NuGet package provider for PowerShell
   Check if NuGet is available in the package providers by running the following command:
   Get-PackageProvider -ListAvailable
   If NuGet is not installed on your system yet, you have to install it.
   Install-PackageProvider -Name NuGet -Force

8. Make sure to comment/uncomment (selectively enable or disable) the functions you want to play with (Elasticsearch and ELKImport are disabled by default). Check out the "Main" in the bottom of the script.

9. Done! :smiley:

Notes:

• Turn off your antivirus protection temporarily or better exclude your MemProcFS-Analyzer directory from scanning.
• Elasticsearch Tips
