Threat Assessment
Reputation is rated Low Risk with a score of 25. No known threat indicators, campaigns, or specific attacker classifications were identified. Abuse confidence score remained null, and blacklisting count reported zero. Behavioral analysis showed no WAF violations, honeypot hits, or enumeration strikes. However, control plane data indicated one DNSBL listing within eight total lists.
Anomalies and Validation
Geolocation data indicated US/Washington/Seattle, but this contradicted RTT physics measurements (15ms average vs 157.7ms minimum possible for claimed distance of 7883.3km). The geolocation consensus was marked as plausible false. Neighborhood classification for the /24 subnet was mostly clean with an abuse density of 0.0769. Overall profile confidence was rated Very Low (0.1667).
Recommendation
