Moving this to v5.25.0 since the TA missed out on this release. |

| description: The following analytic detects the creation of a new local user account on a MacOS system. It leverages osquery logs to identify this activity. Monitoring the creation of local accounts is crucial for a SOC as it can indicate unauthorized access or lateral movement within the network. If confirmed malicious, this activity could allow an attacker to establish persistence, escalate privileges, or gain unauthorized access to sensitive systems and data. | ||

@RavenTait - lets update the data source object to reflect the latest TA information and in the contentctl.yml file

Can we update the formatting all these SPL to make them pretty ? eg :
| - field: dest | ||
| type: system | ||
| score: 18 | ||
| threat_objects: [] |

Lets consider adding process/ process_name as threat objects for all detections in the PR where applicable

| how_to_implement: This detection uses osquery and endpoint security on MacOS. Follow the link in references, which describes how to setup process auditing in MacOS with endpoint security and osquery. Also the [TA-OSquery](https://github.com/d1vious/TA-osquery) must be deployed across your indexers and universal forwarders in order to have the osquery data populate the data models. |
