Observed Attack Techniques (OAT)

Overview

Get a list of observed attack techniques. This endpoint is used to retrieve detailed attack activity observed across the environment and map it to the MITRE ATT&CK framework.

• The response contains an array of activities under the items field.

Trendmicro uses nextLink-based pagination for the /oat endpoint. NextLink-based pagination relies on a link (nextLink) that gives the link for the next call. Each API response contains a nextLink field.
