## Analyst Notes

The high risk score (80/100) despite minimal operator score and clean neighborhood suggests this IP may be involved in intermittent abuse campaigns or has been flagged for specific attack patterns. The presence of SSH access and the certificate for `dealart.co.kr` warrants investigation for potential credential harvesting or phishing activity. The unstable routing state indicates the IP may be dynamically allocated or associated with changing infrastructure.

Priority: Monitor and prepare for blocking until activity patterns are verified.
