Import hashes: File Format?

I want to import some hashes into out ESM Server to have them blocked by Traps. Which format should the input file have?

Re: Import hashes: File Format?

We use the XML format so that we can force the malware verdict. When we deployed Traps we had the assistance of a Traps PSE. He wrote a short powershell script that will take a txt file of SHA256 hashes and convert them into an XML file that you can then import. This works in 3.4.X and 4.0.X.


# This script reads a text file of SHA256 hashes and creates an XML for importing
# into the Traps ESM Policies > Hash Control page.  If these are imported
# 'with verdict', they will appear as "Hash Control" verdicts of "Malware" 

# --------  VARIABLES -----------
# Process name to apply to each hash import
$ImportAsName = "ImportedProcessHash.exe"
# Text file/path of SHA256 hashes to build XML from
$HashStringsFile = ($PSScriptRoot) + "\Hashes.txt"
# File name/path for resulting import XML file
$TrapsImportFile = ($PSScriptRoot) + "\TrapsHashImports.xml"
Write-Host "Creating $TrapsImportFile"
# get an XMLTextWriter to create the XML
$XmlWriter = New-Object System.XMl.XmlTextWriter($TrapsImportFile,$Null)
# choose a pretty formatting:
$xmlWriter.Formatting = 'Indented'
$xmlWriter.Indentation = 1
$XmlWriter.IndentChar = "`t"
# write the header

# create root element "machines" and add some attributes to it
$XmlWriter.WriteComment('Hashes to Import')
$XmlWriter.WriteAttributeString('xmlns', '')
$XmlWriter.WriteAttributeString('xmlns:i', '')

# Read hashes text file and add XML data for each
$Hashes = ((get-content $HashStringsFile) | Sort-Object)
$Hashes | ForEach-Object {
    # Create element HashProcessItem node
    #$XmlWriter.WriteAttributeString('test', 'something')

        # Add pieces of information:

    # Close HashProcessItem node

# Close ArrayOfHashProcessItem node
# finalize the document:

notepad $TrapsImportFile
