High Risk
IP 20.102.40.205 is a critical-risk address operating from the Microsoft Azure cloud infrastructure (AS8075) that has been linked to widespread port-scanning and hacking activity, generating 299 abuse reports across 20 automated honeypot sensors since December 2025 with activity continuing through June 2026. The IP's threat level of 10/10 reflects sustained, high-confidence hostile behavior, making it a definitive candidate for immediate blocking at network perimeters.
Analysis of the 299 reports reveals that port-scanning operations dominate this IP's activity profile, accounting for a significant portion of detections alongside 16 hacking-category incidents, two exploited-host flags, and a single web application attack report. The detection data specifically identifies the Zmap network-scanning tool as the primary user-agent in inbound port-scanning traffic, with accompanying Suricata alerts flagging protocol-detection anomalies and one-direction application-layer communication patterns. The IP was first reported in late 2025 and remained active into mid-2026, indicating persistent rather than transient malicious behavior. Despite originating from a major US cloud provider, the infrastructure is clearly being used for systematic reconnaissance against external targets, a pattern consistent with pre-attack intelligence gathering.
Port scanning represents a serious threat vector because it systematically catalogs exposed services and potential entry points across target networks, effectively mapping the attack surface before more invasive exploitation attempts. The use of Zmap—a fast, efficient scanning utility—suggests the operator is conducting large-scale network surveys, likely to identify vulnerable systems for subsequent compromise. When combined with the confirmed hacking attempts and exploited-host indicators, this scanning activity indicates the IP is actively weaponizing cloud resources to probe and potentially exploit external services. The 69% confidence score reflects reasonable certainty based on honeypot sensor data, though attribution to a specific threat actor remains inconclusive.
Network defenders should immediately block IP 20.102.40.205 at the firewall level given its confirmed malicious profile and ongoing activity. Implementing fail2ban or equivalent dynamic blocking tools that automatically respond to scanning patterns will provide automated protection against repeated probing attempts. Exposed services should be audited regularly to minimize the attack surface, and strict firewall rules should restrict inbound traffic to essential ports only. Monitoring for the Zmap user-agent in inbound connections serves as an effective early-warning mechanism for identifying scanning reconnaissance. Organizations observing connections from this IP should treat them as hostile reconnaissance and log all contact for incident-response purposes.
