Severe Risk
IP 204.76.203.30 is a maximum-threat address originating from the Netherlands that has been linked to 1,112 hacking reports through automated honeypot sensors over a seven-month period, indicating sustained and aggressive intrusion activity.
The address resolves to AS51396 under the network operator Pfcloud UG. With a threat level of 10 out of 10 and an activity frequency rating of 8 out of 10, this IP demonstrates consistent, high-volume hostile behavior. All 20 of the most recent reports categorize the activity as hacking, encompassing intrusion attempts, vulnerability exploitation, and unauthorized access probes. The sustained nature of the activity from October 2025 through May 2026, combined with detection across 20 separate honeypot sensors, indicates persistent and automated attack infrastructure rather than isolated scanning.
The dominant hacking classification represents a composite threat vector that includes automated vulnerability scanning, credential-based attacks, and targeted exploitation of unpatched services. The sheer volume of reports and extended operational window suggest the address is part of an organized campaign, likely operating from a commercial hosting environment that facilitates widespread scanning and attack operations. Organizations with internet-exposed services face direct exposure to compromise attempts originating from this address.
Immediate defensive measures should include blocking or rate-limiting connections from this IP at the network perimeter using standard firewall or access-control rules. Deploying automated response tools such as fail2ban provides dynamic protection against the repeated connection patterns characteristic of this threat. Strengthening authentication mechanisms through strong password policies, multi-factor authentication, and account lockout thresholds significantly reduces the effectiveness of credential-based attacks. Regular vulnerability assessments and timely patching of internet-facing services eliminate the exploitation vectors this address targets.
