📊 Threat Analysis
IP address 151.115.99.187 has been traced to Warsaw, Poland, operating on the network of SCALEWAY. Our threat detection systems have flagged this address based on observed malicious behavior patterns. During its 4-day observation window, we recorded 105 hostile requests from this IP — roughly 26.3 per day on average. Classified as a hosting IP, this address likely runs on a rented server or cloud instance. Attackers prefer datacenter IPs for their high bandwidth and disposable nature. The dual attack vectors of Request Flooding combined with User-Agent Anomaly indicate a coordinated assault rather than opportunistic scanning. With 18 flagged addresses, Poland represents a notable presence in our threat database. At 135/100, this is an extremely high-risk address. All traffic should be considered hostile.
This IP belongs to a hosting or data center provider. Malicious traffic from hosting infrastructure often originates from compromised VPS instances, rented servers used for scanning campaigns, or abused free-tier cloud accounts. Hosting providers typically respond to abuse reports within 24-72 hours.
