Snaffler Output File Parser

Especially in large environments, the Snaffler output gets very large and time-consuming to analyze.

This script parse the Snaffler output file (TSV format required) and:

• Beautify it: Proper tables and different output formats like TXT, CSV, HTML, JSON or PS Gridview.
• The HTML output file:
  • Supports basic sorting and filtering (severity & extension)
  • Highlights the finding keyword in the file preview text
  • Contains direct links to the parent folder of the file and a download link for the file itself.
  • Contains basing information about the Snaffler job.
• Sorts based on the severity (black, red, yellow, green) and then by date or unc.
• Can export all the shares to the Explorer++ config files as bookmarks.
• Generate a list of all shares Snaffler was able to access (might be useful for your client).

Explorer++ Integration

Explorer++ is an alternative file explorer on windows.

The great thing is that unlike the Windows Explorer it can be executed in another user's context including the /netonly switch. This is useful when performing a pentest from a dedicated, non-domain joined pentest notebook or VM.

Donwload Explorer++ https://github.com/derceg/explorerplusplus to the same folder and configure the portable mode:

This will create an config.xml in the same folder.

Parse the Snaffler file using the -pte switch to export all accessible shares as bookmarks to the Explorer++ config XML: .\snafflerParser.ps1 -in Snaffler_output.txt -pte

Explorer++ can then be executed as the user which have access to the shares: runas /user:domain\user /netonly Explorerpp.exe This allows easy access to the shares without authenticate for every share via the bookmark bar:
