## Threat Assessment

The IP demonstrates elevated risk characteristics with active blacklist listings but lacks current service indicators. The geolocation discrepancy between reported US location and Cambodian ASN origin warrants further investigation. The IP may be employed for covert reconnaissance or C2 communications. While no immediate attack activity is observable, the high risk score and blacklist presence justify defensive blocking and enhanced monitoring.

Confidence Level: 12.5%

Status: Recommended for blocking with monitoring
