Severe Risk
IP 204.76.203.225 is a critical-risk address associated with sustained, high-volume hacking activity originating from the Pfcloud UG network in the Netherlands. With a threat level of 10 out of 10, 480 total abuse reports and an activity frequency rating of 8 out of 10, this IP presents a severe danger to any exposed services and should be considered dangerous to permit access to production systems.
According to data from automated honeypot sensors, this address was first reported in April 2026 and remained active through May 2026, representing approximately two months of continuous hostile activity. All 20 of the most recent reports specifically document hacking behavior with a 94 percent confidence score, indicating that the association between this IP and intrusion attempts is well-established. The network is operated by Pfcloud UG (haftungsbeschrankt) under autonomous system AS51396, routing through Netherlands infrastructure. The volume of reports combined with the consistently high activity frequency suggests this is not incidental or misclassified traffic but rather deliberate, persistent scanning and exploitation activity targeting exposed services across the internet.
The dominant threat category for IP 204.76.203.225 is general hacking activity, which encompasses unauthorized access attempts, exploitation of known and zero-day vulnerabilities, and intrusion attempts against exposed services. With 480 cumulative reports, this represents systematic probing of target systems rather than opportunistic or random traffic. The concrete real-world risk includes credential stuffing against authentication portals, exploitation of unpatched software, and attempts to gain initial access for subsequent data theft or network pivoting. Any service reachable from the internet with this IP in its access logs should be treated as a potential compromise attempt requiring investigation.
Site operators should immediately block IP 204.76.203.225 at the firewall or network edge to prevent further contact with internal systems. Deploy fail2ban or equivalent host-based intrusion prevention tools to automatically ban repeated offending addresses. Enforce strong authentication policies including multi-factor authentication on all internet-facing services and ensure systems are patched against known vulnerabilities. Finally, review authentication logs for any successful or attempted logins from this address and consider this IP when tuning intrusion detection signatures for future protection.
