THIS IS A EXPERIMENTAL DETECTION
This detection has been marked experimental by the Splunk Threat Research team. This means we have not been able to test, simulate, or build datasets for this detection. Use at your own risk. This analytic is NOT supported.
The following analytic identifies when a new API token is created. Adversaries who have gained access to a privileged account may add a new token for persistence. This analytic uses the eventType system.api_token.create.

The SPL above uses the following Macros:
okta_new_api_token_created_filter is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.

How To Implement
This analytic is specific to Okta and requires Okta logs to be ingested.
Known False Positives
False positives may be present. Tune Okta and tune the analytic to ensure proper fidelity. Modify risk score as needed.
Associated Analytic Story
|64.0||80||80||$src_user$ has created a new API token within Okta.|
The Risk Score is calculated by the following formula: Risk Score = (Impact * Confidence/100). Initial Confidence and Impact is set by the analytic author.
