## INTELLIGENCE NARRATIVE

The IP address 52.203.233.37 is an AWS EC2 instance operating within the 52.200.0.0/13 BGP prefix. Current analysis shows no active malicious behavior, with no open ports, services, or attack signatures detected. However, the moderate risk score of 50 and presence on two DNS blacklists suggest historical abuse or reputation concerns. The IP's route stability flag is set to false, which is atypical for AWS infrastructure and may indicate routing anomalies or configuration issues.

The subnet 52.203.233.0/24 shows zero abuse density and no neighboring IPs flagged as threats, suggesting this IP operates in isolation. No related entities, campaigns, or correlated IPs were identified in the relationship graph.

SOC analysts should monitor this IP for any changes in behavior, particularly given the route stability anomaly and DNSBL presence. While no immediate blocking is mandated, the provided firewall rules can be applied if the organization requires conservative posture. Continued observation is recommended to track any emergence of malicious activity.
