Severe Risk
IP 176.65.148.66 is a maximum-threat-level Dutch address with 167 confirmed abuse reports spanning August 2025 to May 2026, primarily linked to sustained hacking activity including intrusion attempts and exploitation of vulnerable services.
Automated honeypot sensors recorded 20 distinct hacking events associated with this IP over a nine-month observation window, yielding an 80% confidence score that the activity is malicious in nature. The address originates from Pfcloud UG's network infrastructure in the Netherlands, which has been flagged across multiple security monitoring feeds. Despite a moderate activity frequency rating of 4/10, the sustained reporting period combined with a 10/10 threat level indicates deliberate, persistent targeting rather than opportunistic scanning. The consistent detection across varied honeypot architectures suggests this IP represents an established threat rather than transient malicious traffic.
Hacking activity encompasses a broad spectrum of unauthorized access techniques including vulnerability exploitation, credential attacks, and attempts to compromise exposed services. A maximum threat severity rating typically indicates active exploitation attempts, often targeting known vulnerabilities in unpatched systems or brute-force campaigns against authentication entry points. Services such as SSH, RDP, web interfaces, or inadequately secured databases face the highest risk when targeted by an address with this report volume and threat profile.
Site operators should immediately block or heavily rate-limit connections from this address at the network perimeter. Deploying automated defensive tools such as fail2ban can dynamically respond to repeated connection attempts from this source. Enforcing strong, unique passwords alongside key-based authentication for any exposed services significantly reduces the effectiveness of credential-based attacks. Regular security patching cycles and continuous intrusion detection monitoring are essential to identify and neutralize exploitation attempts before they succeed.
