Substantial Risk
IP 204.76.203.215 is a high-risk Dutch address that has generated 1086 abuse reports for hacking activity detected by automated honeypot sensors over approximately five months, with a threat level of 8/10 and a 90% confidence score indicating reliable attribution of malicious behavior.
Operating from the Pfcloud UG network (ASN AS51396) in the Netherlands, this address was first reported in December 2025 with continued activity logged through April 2026, representing a persistent threat rather than an isolated incident. The volume of reports significantly exceeds typical opportunistic scanning, suggesting sustained automated or semi-automated intrusion activity directed at exposed services. All 1086 reports were generated by automated honeypot sensors, which are designed specifically to capture and document unauthorized connection attempts and exploit probes without requiring manual intervention from network defenders.
The dominant threat category for IP 204.76.203.215 is general hacking activity, encompassing unauthorized access attempts and exploitation probes against target systems. Observed attack patterns include generic connection attempts and Suricata alerts documenting protocol mismatches between the attacking client and expected service responses, a technique sometimes used to fingerprint vulnerable configurations or trigger unexpected application behavior. This category of activity poses a concrete risk to any exposed service, particularly those with outdated software, weak authentication mechanisms, or known vulnerabilities that have not been patched. The sustained activity frequency and high report volume indicate this address is actively cycling through targets rather than conducting a single opportunistic scan.
Network administrators should implement immediate defensive measures including rate-limiting and automatic blocking of this IP address at the firewall or intrusion prevention system level. Deploying tools such as fail2ban or equivalent log-based auth failure monitoring can automate the identification and temporary suspension of repeated connection attempts from this source. Ensuring all exposed services run current security patches, enforcing strong authentication policies, and maintaining active intrusion detection monitoring will reduce the attack surface available to this and similar hostile addresses. Regular review of honeypot and firewall logs will help identify whether the activity from this address coincides with successful reconnaissance against your specific infrastructure.
