Properties

MSFT_MpThreat returns 10 properties:

'CategoryID','DidThreatExecute','IsActive','Resources','RollupStatus','SchemaVersion',
'SeverityID','ThreatID','ThreatName','TypeID'

Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:

Get-CimInstance -ClassName MSFT_MpThreat -Namespace root/microsoft/windows/defender -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class MSFT_MpThreat exist. This is normal behavior.

Either the class is not implemented on your system (may be deprecated or due to missing drivers, i.e. CIM_VideoControllerResolution), or there are simply no physical representations of this class currently available (i.e. Win32_TapeDrive).

CategoryID

UINT8

Category ID - Enumeration

CategoryID returns a numeric value. To translate it into a meaningful text, use any of the following approaches:

Use a PowerShell Hashtable

$CategoryID_map = @{
= 'INVALID'
= 'ADWARE'
= 'SPYWARE'
= 'PASSWORDSTEALER'
= 'TROJANDOWNLOADER'
= 'WORM'
= 'BACKDOOR'
= 'REMOTEACCESSTROJAN'
= 'TROJAN'
= 'EMAILFLOODER'
= 'KEYLOGGER'
= 'DIALER'
= 'MONITORINGSOFTWARE'
= 'BROWSERMODIFIER'
= 'COOKIE'
= 'BROWSERPLUGIN'
= 'AOLEXPLOIT'
= 'NUKER'
= 'SECURITYDISABLER'
= 'JOKEPROGRAM'
= 'HOSTILEACTIVEXCONTROL'
= 'SOFTWAREBUNDLER'
= 'STEALTHNOTIFIER'
= 'SETTINGSMODIFIER'
= 'TOOLBAR'
= 'REMOTECONTROLSOFTWARE'
= 'TROJANFTP'
= 'POTENTIALUNWANTEDSOFTWARE'
= 'ICQEXPLOIT'
= 'TROJANTELNET'
= 'FILESHARINGPROGRAM'
= 'MALWARE_CREATION_TOOL'
= 'REMOTE_CONTROL_SOFTWARE'

= 'TROJAN_PROXYSERVER'
= 'VIRUS'
= 'KNOWN'
= 'UNKNOWN'
= 'SPP'
= 'BEHAVIOR'
= 'VULNERABILTIY'
= 'POLICY'
}

Use a switch statement

switch([int]$value)
{
        {'INVALID'}
        {'ADWARE'}
        {'SPYWARE'}
        {'PASSWORDSTEALER'}

       {'DIALER'}
       {'MONITORINGSOFTWARE'}
       {'BROWSERMODIFIER'}
       {'COOKIE'}
       {'BROWSERPLUGIN'}
       {'AOLEXPLOIT'}
       {'NUKER'}
       {'SECURITYDISABLER'}

       {'ICQEXPLOIT'}
       {'TROJANTELNET'}
       {'FILESHARINGPROGRAM'}
       {'MALWARE_CREATION_TOOL'}
       {'REMOTE_CONTROL_SOFTWARE'}
       {'TOOL'}

       {'SPP'}
       {'BEHAVIOR'}
       {'VULNERABILTIY'}

#endregion define hashtable

<#
  a calculated property is defined by a hashtable with keys "Name" and "Expression"
  "Name" defines the name of the property (in this example, it is "CategoryID", but you can rename it to anything else)
  "Expression" defines a scriptblock that calculates the content of this property
  in this example, the scriptblock uses the hashtable defined earlier to translate each numeric
  value to its friendly text counterpart:

# is defined by the hashtable in $CategoryID:

# ...or dump content of property CategoryID:
$friendlyValues = Get-CimInstance -Class MSFT_MpThreat | 
    Select-Object -Property $CategoryID |
    Select-Object -ExpandProperty CategoryID

# output values

Use $CategoryID_map to directly translate raw values from an instance

<# 
  this example uses a hashtable to manually translate raw numeric values 
  for property "MSFT_MpThreat" to friendly text. This approach is ideal when
  there is just one instance to work with.

  Note: to use other properties than "MSFT_MpThreat", look up the appropriate 
  translation hashtable for the property you would like to use instead.

SeverityID

UINT8

Severity ID - Enumeration

SeverityID returns a numeric value. To translate it into a meaningful text, use any of the following approaches:

Use a PowerShell Hashtable

$SeverityID_map = @{
= 'Unknown'
= 'Low'
= 'Moderate'
= 'High'
= 'Severe'
}

Use a switch statement

switch([int]$value)
{
  0          {'Unknown'}
  1          {'Low'}
  2          {'Moderate'}
  3          {'High'}
  4          {'Severe'}
  default    {"$value"}
}

Use Enum structure

Enum EnumSeverityID
{
  Unknown    = 0
  Low        = 1
  Moderate   = 2
  High       = 3
  Severe     = 4
}

Examples

Use $SeverityID_map in a calculated property for Select-Object

<# 
  this example uses a hashtable to translate raw numeric values for 
  property "SeverityID" to friendly text

  Note: to use other properties than "SeverityID", look up the appropriate 
  translation hashtable for the property you would like to use instead.

List all instances of MSFT_MpThreat

Get-CimInstance -ClassName MSFT_MpThreat -Namespace root/microsoft/windows/defender

Learn more about Get-CimInstance and the deprecated Get-WmiObject.

View all properties

Get-CimInstance -ClassName MSFT_MpThreat -Namespace root/microsoft/windows/defender -Property *

Get-CimInstance -ClassName MSFT_MpThreat -Namespace root/microsoft/windows/defender -KeyOnly

Selecting Properties

To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.

Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.

Selecting Properties

The code below lists all available properties. Remove the ones you do not need:

$properties = 'CategoryID',
              'DidThreatExecute',
              'IsActive',
              'Resources',
              'RollupStatus',
              'SchemaVersion',
              'SeverityID',
              'ThreatID',
              'ThreatName',
              'TypeID'
Get-CimInstance -ClassName MSFT_MpThreat -Namespace root/microsoft/windows/defender | Select-Object -Property $properties

Limiting Network Bandwidth

If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:

Get-CimInstance -Class MSFT_MpThreat -Namespace root/microsoft/windows/defender -Property $property | 
Select-Object -Property $property

Selecting Instances

To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).

The parameter -Filter runs a simple query.

Listing all instances where the property Caption starts with “A”

Get-CimInstance -Class MSFT_MpThreat -Namespace root/microsoft/windows/defender -Filter 'Caption LIKE "a%"' 

Using a WQL Query

The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:

Get-CimInstance -Query "SELECT Resources, ThreatName, CategoryID, IsActive FROM MSFT_MpThreat WHERE Caption LIKE 'a%'" -Namespace root/microsoft/windows/defender

Any property you did not specify is still present but empty. You might need to use Select-Object to remove all unwanted properties:
Get-CimInstance -Query "SELECT Resources, ThreatName, CategoryID, IsActive FROM MSFT_MpThreat WHERE Caption LIKE 'a%'" -Namespace root/microsoft/windows/defender | Select-Object -Property Resources, ThreatName, CategoryID, IsActive

Accessing Remote Computers

To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.

Authenticating as Current User

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with your current identity:
$result = Get-CimInstance -ClassName MSFT_MpThreat -Namespace root/microsoft/windows/defender -ComputerName $list 
$result

Authenticating as Different User

Use a CIMSession object to authenticate with a new identity:

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred

$result = Get-CimInstance MSFT_MpThreat -Namespace root/microsoft/windows/defender -CimSession $session

# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session

$result

Requirements

To use MSFT_MpThreat, the following requirements apply:

PowerShell

Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.

If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.

Operating System

MSFT_MpThreat was introduced on clients with Windows 8.1 [desktop apps only] and on servers with Windows Server 2012 R2 [desktop apps only].

Namespace

MSFT_MpThreat lives in the Namespace Root/Microsoft/Windows/Defender. This is not the default namespace. Use parameter -Namespace root/microsoft/windows/defender with all CIM cmdlets..

Implementation

MSFT_MpThreat is implemented in ProtectionManagement.dll and defined in ProtectionManagement.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\ProtectionManagement.mof
