# Observed Attack Techniques (OAT)

## Overview

Get a list of observed attack techniques through the [TrendAI Vision One API](https://automation.trendmicro.com/xdr/api-v3/#tag/Observed-Attack-Techniques/paths/~1v3.0~1oat~1detections/get) using the **HTTP Pull** Listener.

## HTTP Pull Listener configuration

In Falcon Onum, go to the **Listeners** area and click **New Listener > HTTP Pull**. Give a name to your new Listener and enter the following data:

### Parameters

Add the following parameter:

* **Name** - `trendMicroDomain`
* **Value** - Enter your Trend Micro domain.

### Secrets

You must define these credentials in Onum:

* `trendMicroBearerToken` will reference your Trend Micro token.

To do it, click **Add element** and enter a **Name** for the secret (in this case, `trendMicroBearerToken`). Then, click the **Value** field and select **New secret** to create a new one:

* Give the secret a **Name**.
* Turn off the **Expiration date** option.
* Click **Add new value** and paste the secret corresponding to the value.
* Click **Save**.

You can now select the secret you just created in the **Value** field list.

### Setup

After entering the required parameters and secrets, you can choose to manually enter the rest of configuration fields, or simply paste the given YAML:

{% tabs %}
{% tab title="Config as YAML" %}
Toggle **ON** the **Config as YAML** option to enable a free text field where you can paste the following YAML:

```yaml
withTemporalWindow: true
temporalWindow:
  duration: 5m
  offset: 5m
  tz: UTC
  format: RFC3339
withAuthentication: false
withEnumerationPhase: false
collectionPhase:
  paginationType: "responseBodyLink"
  responseBodyLinkSelector: ".nextLink"
  limit: 100
  request:
    method: GET
    url: "https://${parameters.trendMicroDomain}/v3.0/oat/detections"
    headers:
      - name: Accept
        value: application/json
      - name: Authorization
        value: "Bearer ${secrets.trendMicroBearerToken}"
    queryParams:
      - name: detectedStartDateTime
        value: "${temporalWindow.from}"
      - name: detectedEndDateTime
        value: "${temporalWindow.to}"
  output:
    select: ".items"
    map: "."
    outputMode: element
```

{% endtab %}

{% tab title="Manually configure" %}
**Temporal Window**

Toggle **ON** to add a temporal window for events. This repeatedly shifts the time window over which data is collected.

* **Duration** - `5m`
* **Offset** - `5m`
* **Format** - `RFC3339`

**Collection Phase**

* **Pagination Type** - `Next Link at Response Body`
* **Selector** - `.nextLink`
* **Request** 
  * **Response Type** - `JSON`
  * **Method** - `GET`
  * **URL** - `https://${parameters.trendMicroDomain}/v3.0/oat/detections`
* **Headers**
  * **Name** - `Accept`
  * **Value** - `application/json`
  * **Name** - `Authorization`
  * **Value** - `Bearer ${secrets.trendMicroBearerToken}`
* **Query Params**
  * **Name** - `detectedStartDateTime`
  * **Value** - `${temporalWindow.from}`
  * **Name** - `detectedEndDateTime`
  * **Value** - `${temporalWindow.to}`
* **Output** 
  * **Select** - `.items`
  * **Map** - `.`
  * **Output Mode** - `element`
    {% endtab %}
    {% endtabs %}

When you're done, click **Create labels** to move on to the next step and define the required [Labels](https://app.gitbook.com/o/9sm794iTBacZSmhxRER6/s/kxZeV4nlXcIAjMGZxzLI/the-workspace/listeners/labels) if needed.
