Severe Risk
IP address 204.76.203.56 is a critical-risk Dutch cloud infrastructure address that generated 1,096 abuse reports between January and April 2026, with automated honeypot sensors flagging it for sustained hacking activity including intrusion attempts and exploitation of vulnerable services.
Operating from AS51396 under Pfcloud UG (haftungsbeschrankt), this address demonstrates an activity frequency of 8 out of 10 and a threat level of 10 out of 10, with a 90 percent confidence score across 20 independent automated honeypot detections. The four-month reporting window and consistent detection volume indicate persistent, deliberate targeting rather than opportunistic scanning, a pattern characteristic of either compromised cloud infrastructure or rented attack infrastructure commonly observed in abuse ecosystems.
Hacking activity encompasses a broad spectrum of intrusion techniques, including vulnerability exploitation, credential attacks, and unauthorized access attempts against exposed services. For any organization running accessible SSH, RDP, web applications, or database services, repeated connection attempts from this address represent a concrete operational risk. The sustained frequency and high report volume suggest the actor is actively probing for unpatched software, weak authentication configurations, or exploitable application flaws at scale, potentially preceding more targeted compromise if a vulnerability is identified.
Site operators should immediately block or rate-limit traffic from this address at the firewall or network edge, implement automated abuse-response tooling such as fail2ban to parse logs and update firewall rules dynamically, ensure all exposed services are fully patched and running current versions, and enforce strong multi-factor authentication on remote-access protocols. Ongoing monitoring of connection logs for patterns consistent with this IP's reported activity will help identify any successful reconnaissance before it escalates to a full breach.
