Create a Custom Detection Script for Bitdefender Anti-Ransomware (PowerShell)

Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM) and Microsoft Intune use Detection Rules to determine the presence of Applications & Win32 Apps. The detection rules ensure that application installations only begin to run if the application is not already installed on the device. This article will serve as an informative guide and give you a clear understanding of how to create an updated custom detection script for each new version of Bitdefender Anti-Ransomware using PowerShell.

$BDAntiRansomwareExe.FullName
$BDAntiRansomwarePath = $($BDAntiRansomwareExe.FullName).Replace("C:\Program Files\","")
$FileVersion = (Get-Item -Path "$($BDAntiRansomwareExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw

## Create Text File with Bitdefender Anti-Ransomware File Detection Method
$FilePath = "C:\Windows\Temp\BDAntiRansomware_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$BDAntiRansomwarePath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw -ge `"$FileVersion`"){"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
Add-Content -Path "$FilePath" -Value "else {"
Add-Content -Path "$FilePath" -Value "Exit 1"
