tiIndicator resource type (deprecated)

Namespace: microsoft.graph

Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Note

The tiIndicator entity is deprecated and will be removed by April 2026.

Represents data used to identify malicious activities.

If your organization works with threat indicators, either by generating your own, obtaining them from open source feeds, sharing with partner organizations or communities, or by purchasing feeds of data, you might want to use these indicators in various security tools for matching with log data. The tiIndicators entity allows you to upload your threat indicators to Microsoft security tools for the actions of allow, block, or alert.

Threat indicators uploaded via tiIndicator are used with Microsoft threat intelligence to provide a customized security solution for your organization. When using the tiIndicator entity, specify the Microsoft security solution you want to utilize the indicators via the targetProduct property, and specify the action (allow, block, or alert) to which the security solution should apply the indicators via the action property.

Currently, targetProduct supports the following products:

• Microsoft Defender for Endpoint – Supports the following tiIndicators methods:

  • Get tiIndicator
  • Create tiIndicator
  • List tiIndicators
  • Update
  • Delete

  Note

  The following indicator types are supported by Microsoft Defender for Endpoint targetProduct:

  • Files
  • IP addresses: Microsoft Defender for Endpoint supports destination IPv4/IPv6 only – set property in networkDestinationIPv4 or networkDestinationIPv6 properties in Microsoft Graph Security API tiIndicator.
  • URLs/domains

  There's a limit of 15,000 indicators per tenant for Microsoft Defender for Endpoint.

• Microsoft Sentinel – Only existing customers can use the tiIndicator API to send threat intelligence indicators to Microsoft Sentinel. For the most up-to-date, detailed instructions on how to send threat intelligent indicators to Microsoft Sentinel, see Connect your threat intelligence platform to Microsoft Sentinel.

For details about the types of indicators supported and limits on indicator counts per tenant, see Manage indicators.

activityGroupNames	String collection	The cyber threat intelligence name(s) for the parties responsible for the malicious activity covered by the threat indicator.
additionalInformation	String	A catchall area for extra data from the indicator that is not specifically covered by other tiIndicator properties. The security tool specified by targetProduct typically does not utilize this data.

diamondModel	diamondModel	The area of the Diamond Model in which this indicator exists. Possible values are: unknown, adversary, capability, infrastructure, victim.
expirationDateTime	DateTimeOffset	DateTime string indicating when the Indicator expires. All indicators must have an expiration date to avoid stale indicators persisting in the system. The Timestamp type represents date and time information using ISO 8601 format and is always in UTC time. For example, midnight UTC on Jan 1, 2014 is 2014-01-01T00:00:00Z. Required.
externalId	String	An identification number that ties the indicator back to the indicator provider’s system (for example, a foreign key).
id	String	Created by the system when the indicator is ingested. Generated GUID/unique identifier. Read-only.
ingestedDateTime	DateTimeOffset	Stamped by the system when the indicator is ingested. The Timestamp type represents date and time information using ISO 8601 format and is always in UTC time. For example, midnight UTC on Jan 1, 2014 is 2014-01-01T00:00:00Z
isActive	Boolean	Used to deactivate indicators within system. By default, any indicator submitted is set as active. However, providers may submit existing indicators with this set to ‘False’ to deactivate indicators in the system.
killChain	killChain collection	A JSON array of strings that describes which point or points on the Kill Chain this indicator targets. See ‘killChain values’ below for exact values.
knownFalsePositives	String	Scenarios in which the indicator may cause false positives. This should be human-readable text.

passiveOnly	Boolean	Determines if the indicator should trigger an event that is visible to an end-user. When set to ‘true,’ security tools won't notify the end user that a ‘hit’ has occurred. This is most often treated as audit or silent mode by security products where they'll simply log that a match occurred but won't perform the action. Default value is false.
severity	Int32	An integer representing the severity of the malicious behavior identified by the data within the indicator. Acceptable values are 0 – 5 where 5 is the most severe and zero isn't severe at all. Default value is 3.
