Powershell script to retrieve all detection method scripts and output them


Last year i wrote a blogpost about how to get all the powershell scripts used as detection methods and since then i have refined that script a bit and also added logic for it to now output any detection method using scripts regardless if its Powershell, VBScript or Javascript.

I hope this can be useful to someone out there in cyberspace.

 

The Script

$Script = ([Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer]::DeserializeFromString($App.SDMPackageXML)).DeploymentTypes[0].Installer
if ($Script.DetectionScript -ne $Null)
{
$PSscript = ([Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer]::DeserializeFromString($App.SDMPackageXML)).DeploymentTypes[0].Installer.DetectionScript

Switch ($PSscript.Language)
{
"PowerShell" { Out-File -FilePath "$Filepath$($App.LocalizedDisplayName).ps1" -InputObject $PSscript.Text }
"VBScript" { Out-File -FilePath "$Filepath$($App.LocalizedDisplayName).vbs" -InputObject $PSscript.Text }
"JavaScript" { Out-File -FilePath "$Filepath$($App.LocalizedDisplayName).JS" -InputObject $PSscript.Text }
}

}

}

}

Example

 

You need to run script locally from your siteserver.

get-DetectionMethodScripts.ps1 -DestinationPath "C:\temp\scripts\"

 

and it will output all the detection methods that uses scripts to that folder. One for each application and names the file after the application.

 

Until next time, cheers !
