uncommon troubleshooting activity or due to a compromised account. A compromised account may be used by a threat actor
to engage in system network configuration discovery in order to increase their understanding of connected networks and
hosts. This information may be used to shape follow-up behaviors such as lateral movement or additional discovery.
