Retrieve Tasks

Filtering Tasks

When retrieving Tasks from ThreatConnect, it is possible to filter the results. Results can be filtered on the following data points:

Filter	Data Type	Operator(s)
name	string	`=`, `^`
dateAdded	date	`<`, `>`
status	string	`=`, `!`
assignee	string	`=`
escalatee	string	`=`
overdue	boolean	`=`
escalated	boolean	`=`
dueDate	date	`<`, `>`
reminded	boolean	`=`

Hint

The “^” character means “starts with”. For example, this character would be used to find all URL Indicators that start with http://xn-- or all Groups whose name starts with APT.

Note

The =, <, >, and ^ operators in any filters must be URL encoded as follows:

Character	URL Encoded Form
=	`%3D`
<	`%3C`
>	`%3E`
^	`%5E`

The following query will return all Tasks that start with “Test” (name^Test):

GET /v2/tasks/?filters=name%5ETest

The following query will return all Tasks whose name is “Test” (name=Test):

GET /v2/tasks/?filters=name%3DTest

The following query will return all Tasks whose status is “Not Started” (status=Not Started):

GET /v2/tasks/?filters=status%3DNot%20Started

The following query will return all Tasks assigned to the user with the username “johndoe@example.com” (assignee=johndoe@example.com):

GET /v2/tasks/?filters=assignee%3Djohndoe%40example.com

The following query will return all Tasks that will be escalated to the user with the username “manager@example.com” (escalatee=manager@example.com):

GET /v2/tasks/?filters=escalatee%3Dmanager%40example.com

The following query will return all overdue Tasks (overdue=true):

GET /v2/tasks/?filters=overdue%3Dtrue

The following query will return all escalated Tasks (escalated=true):

GET /v2/tasks/?filters=escalated%3Dtrue

The following query will return all Tasks with a due date after 2017-07-25 (dueDate>2017-07-25):

GET /v2/tasks/?filters=dueDate%3E2017-07-25

The following query will return all Tasks for which a reminder has been sent (reminded=true):

GET /v2/tasks/?filters=reminded%3Dtrue

Retrieve Multiple Tasks

To retrieve all Tasks in the default Owner, use the following query:

GET /v2/tasks

JSON Response:

      },
      {
        "id": "54322",
        "name": "[email protected]",
        "type": "EmailAddress",
        "webLink": "https://app.threatconnect.com/auth/victim/victim.xhtml?victim=123"
      }
    ]
  }
}

You can also find associated Victim Assets of a given type using the following format:

GET /v2/tasks/{taskId}/victimAssets/{victimAssetType}

Create Tasks

The most basic format used for creating a Task is:

POST /v2/tasks/
Content-type: application/json; charset=utf-8

{
  "name": "Test Task"
}

Some Task types require additional fields when being created. Refer to the table below for the available fields for Tasks:

Valid Fields	Required	Example Value
name	TRUE	“New Task”
assignee	FALSE	[ {“userName” : “analyst@threatconnect.com”} ]
escalatee	FALSE	[ {“userName” : “manager@threatconnect.com”} ]
dueDate	FALSE	“2018-03-20T13:36:53-04:00”
escalationDate	FALSE	“2018-07-13T13:36:53-04:00”
description	FALSE	“Send to IR team for triage.”

For example, the query below will create a Task in the default Owner with the name Test Task that is due on 2017-07-13:

POST /v2/tasks/
Content-type: application/json; charset=utf-8

{
  "name": "Test Task",
  "dueDate": "2017-07-13T13:36:53-04:00"
}

JSON Response:

{
  "status": "Success",
  "data": {
    "task": {
      "id": "54321",
      "name": "Test Task",
      "owner": {
        "id": 1,
        "name": "Example Organization",
        "type": "Organization"
      },
      "dateAdded": "2017-07-13T17:50:17",
      "webLink": "https://app.threatconnect.com/auth/task/task.xhtml?task=54321",
      "status": "Not Started",
      "escalated": false,
      "reminded": false,
      "overdue": false,
      "dueDate": "2017-07-13T13:36:53-04:00"
    }
  }
}

The code below will function as the code above, but it will also assign the Task to the user with the username johndoe@example.com:

POST /v2/tasks/
Content-type: application/json; charset=utf-8

{
  "name": "Test Task",
  "dueDate": "2017-07-13T13:36:53-04:00",
  "assignee": [
    {
      "userName": "[email protected]"
    }
  ]
}

JSON Response:

{
  "status": "Success",
  "data": {
    "task": {
      "id": "54321",
      "name": "Test Task",
      "owner": {
        "id": 1,
        "name": "Example Organization",
        "type": "Organization"
      },
      "dateAdded": "2017-07-13T17:50:17",
      "webLink": "https://app.threatconnect.com/auth/task/task.xhtml?task=54321",
      "status": "Not Started",
      "escalated": false,
      "reminded": false,
      "overdue": false,
      "dueDate": "2017-07-13T13:36:53-04:00",
      "assignee": [
        {
          "userName": "[email protected]",
          "firstName": "John",
          "lastName": "Doe"
        }
      ]
    }
  }
}

The code below will function as the code above, but it will also assign the Task to the two users whose usernames are johndoe@example.com and janedoe@example.com:

POST /v2/tasks/
Content-type: application/json; charset=utf-8

{
  "name": "Test Task",
  "dueDate": "2017-07-13T13:36:53-04:00",
  "assignee": [
    {
      "userName": "[email protected]"
    },
    {
      "userName": "[email protected]"
    }
  ]
}

The code below will function as the code above, but instead of assigning the Task to the users johndoe@example.com and janedoe@example.com, it will assign the Task to johndoe@example.com and set janedoe@example.com as the escalatee:

POST /v2/tasks/
Content-type: application/json; charset=utf-8

{
  "name": "Test Task",
  "dueDate": "2017-07-13T13:36:53-04:00",
  "assignee": [
    {
      "userName": "[email protected]"
    }
  ],
  "escalatee": [
    {
      "userName": "[email protected]"
    }
  ]
}

Create Task Metadata

Create Task Attributes

To add an attribute to a Task, use the following format:

POST /v2/tasks/{taskId}/attributes
Content-type: application/json; charset=utf-8

{
  "type" : {attributeType},
  "value" : "Test Attribute",
  "displayed" : true
}

For example, if you wanted to add a Description Attribute to the Task with ID 12345, you would use the following query:

POST /v2/tasks/12345/attributes
Content-type: application/json; charset=utf-8

{
  "type" : "Description",
  "value" : "Test Description",
  "displayed" : true

      "type": "Description",
      "dateAdded": "2017-07-13T17:50:17",
      "lastModified": "2017-07-13T17:50:17",
      "displayed": true,
      "value": "Test Description"
    }
  }
}

To add a Security Label to an Attribute, use the following format, where {securityLabel} is replaced with the name of a Security Label that already exists in the Owner:

POST /v2/tasks/{taskId}/attributes/{attributeId}/securityLabels/{securityLabel}

For example, the query below will add a TLP:AMBER Security Label to the Attribute on the Task:

POST /v2/tasks/12345/attributes/54321/securityLabels/TLP%3AAMBER

Note

In order to add a Security Label to an Attribute, the Security Label must already exist. The query above will not create a new Security Label. If you specify a Security Label that does not exist, it will return an error.

Create Task Security Labels

To add a Security Label to a Task, use the following format, where {securityLabel} is replaced with the name of a Security Label that already exists in the Owner:

POST /v2/tasks/{taskId}/securityLabels/{securityLabel}

For example, the query below will add a TLP:AMBER Security Label to the Task with ID 12345:

POST /v2/tasks/12345/securityLabels/TLP%3AAMBER

JSON Response:

{
  "status": "Success"
}

Note

In order to add a Security Label to a Task, the Security Label must already exist. The query above will not create a new Security Label. If you specify a Security Label that does not exist, it will return an error.

Create Task Tags

To add a Tag to a Task, use the following format, where {tagName} is replaced with the name of the Tag you want to add to the Task:

POST /v2/tasks/{taskId}/tags/{tagName}

For example, the query below will add the Nation State Tag to the Task whose ID is 12345:

POST /v2/tasks/12345/tags/Nation%20State

JSON Response:

{
  "status": "Success"
}

Note

The length of a Tag is limited to 128 characters.

Attention

When applying ATT&CK Tags to an object, do not include the corresponding technique/sub-technique ID in the Tag’s name. For example, to apply the T1566 - Phishing ATT&CK Tag to an object, use Phishing as the Tag name.

Also, if you applied a new Tag to an object and that Tag matches a synonymous Tag listed in a Tag normalization rule, it will be converted to the main Tag listed in the rule. Similarly, if you applied a new Tag to an object and that Tag matches an ATT&CK Tag, it will be converted to that ATT&CK Tag.

Create Task Associations

Associate Group to Task

To associate a Task with a Group, use a query in the following format:

POST /v2/tasks/{taskId}/groups/{associatedGroupType}/{associatedGroupId}

Replace {associatedGroupType} with one of the following Group types:

adversaries
attackPatterns
campaigns
coursesOfAction
documents
emails
events
incidents
intrusionSets
malware
reports
signatures
tactics
threats
tools
vulnerabilities

For example, the query below will associate a Task with ID 12345 with an Incident with the ID 54321:

POST /v2/tasks/12345/groups/incidents/54321

JSON Response:

{
  "status": "Success"
}

Associate Indicator to Task

To associate a Task with an Indicator, use a query in the following format:

POST /v2/tasks/{taskId}/indicators/{associatedIndicatorType}/{associatedIndicator}

For example, the query below will associate the Task with ID 12345 with the IP Address 0.0.0.0:

POST /v2/tasks/12345/indicators/addresses/0.0.0.0

JSON Response:

{
  "status": "Success"
}

Associate Victim to Task

To associate a Task with a Victim, use a query in the following format:

POST /v2/tasks/{taskId}/victims/{victimId}

For example, the query below will associate the Task with ID 12345 with the Victim with ID 54321:

POST /v2/tasks/12345/victims/54321

JSON Response:

{
  "status": "Success"
}

Warning

In order to associate a Victim with any item, that Victim must have at least one Victim Asset.

Update Tasks

The basic format used to update a Task is:

PUT /v2/tasks/{taskId}
{
  {updatedField}: {updatedValue}
}

When updating the fields on a Task, you can change any of the following fields:

Valid Fields	Example Value
name	“New Task”
assignee	{ “userName” : [”analyst@threatconnect.com”] }
escalatee	{ “userName” : [”manager@threatconnect.com”] }
dueDate	“2016-03-20T13:36:53-04:00”
description	“Send to IR team for triage.”
status	“Not Started”

}

JSON Response:

{
  "status": "Success",
  "data": {
    "task": {
      "id": "12345",
      "name": "New Task Name",
