The endpoint hosted the fe2.update.microsoft.com certificate and resided within a subnet containing one threat sibling among five active neighbors. Despite the cloud infrastructure classification, the address received a moderate risk score of 60 and high severity recommendations to block traffic. Data coherence scored 48 due to contradictions between claimed United Kingdom geolocation and United States TLS certificate origins, alongside RTT physics violations.
