Maximum Danger
IP 45.156.87.127 is a critical-risk address associated with sustained hacking activity, having accumulated 407 abuse reports from automated honeypot sensors over a four-month observation window with a threat level rating of 10/10 and a 94% confidence score that this IP poses a genuine security threat.
The activity was first reported in March 2026 and continued through June 2026, indicating persistent hostile scanning behaviour rather than an isolated incident. All 407 reports cite hacking as the primary threat category, with detection exclusively attributed to automated honeypot sensors. The geographic origin traces to the Netherlands operating through AS51396 under the network operator Pfcloud UG (haftungsbeschrankt). The Suricata intrusion detection system flagged the address specifically for ICMP Destination Unreachable communications, a pattern consistent with network reconnaissance and port-scanning operations where blocked or filtered ports return administrative prohibition responses. With an activity frequency rating of 8/10, this IP demonstrates near-continuous hostile engagement against exposed honeypot infrastructure.
The dominant hacking classification encompasses unauthorized access attempts, vulnerability exploitation probing, and reconnaissance scanning activities. The ICMP communication pattern observed indicates the address is actively mapping network defences and identifying accessible attack surfaces by sending packets to determine which ports and services are reachable. This reconnaissance phase typically precedes more targeted exploitation attempts against discovered vulnerabilities. The sustained volume of reports over four months confirms this is not opportunistic scanning but organized, repeated hostile activity against internet-facing systems.
Site operators with publicly accessible services should block this address at the network perimeter firewall level and implement rate-limiting on inbound connections. Deploying fail2ban or similar dynamic blocking tools that automatically respond to repeated hostile patterns provides automated protection. Enforcing strong authentication on all exposed services, maintaining current security patches, and monitoring logs for reconnaissance activity from this address and adjacent ranges will reduce exposure to the probing behaviour this IP demonstrates.
