Maximum Danger
IP 176.65.149.251 is a critical-risk address that automated honeypot sensors have flagged 530 times for hacking activity since its first detection in August 2025, with a threat-level score of 10 out of 10 and an 81 percent confidence rating that this traffic represents malicious intent. The Netherlands-based IP, registered to Pfcloud UG under autonomous system AS51396, has generated consistent abuse reports through at least 20 distinct honeypot sensors, indicating persistent and widespread automated scanning behaviour across the threat-intelligence community.
Analysis of the reported data reveals sustained hostile activity spanning approximately five months, from August through December 2025, with the dominant threat category classified as general hacking attempts. The volume of 530 independent reports is notable given the short observation window, and the involvement of 20 separate detection sensors suggests this address participates in large-scale, distributed scanning campaigns rather than isolated opportunistic probes. Pfcloud UG, the network operator, hosts this address in a Netherlands jurisdiction, which is frequently leveraged by threat actors seeking jurisdictions with moderate enforcement cooperation.
Hacking activity, as logged by these sensors, encompasses intrusion attempts, vulnerability probing and unauthorized-access enumeration against exposed services. For an organisation with directly internet-facing systems, traffic from this address poses a concrete risk of initial compromise, lateral movement and data exfiltration if vulnerabilities exist in publicly accessible software. The automated nature of these attacks means they operate continuously across thousands of potential targets, making any unhardened service a candidate for exploitation.
Site operators should immediately block or rate-limit traffic originating from this address at the network perimeter, using standard defensive tools such as fail2ban or equivalent firewall rules to prevent repeated connection attempts. Ensuring all internet-facing applications and operating systems are patched against known vulnerabilities significantly reduces the attack surface available to this scanner. Deploying intrusion-detection signatures tuned to the specific probing patterns associated with automated honeypot reports will enhance situational awareness. Finally, enforcing strong authentication mechanisms, including key-based authentication for administrative services and multi-factor verification for remote-access portals, will harden exposed entry points against the credential-guessing and privilege-escalation techniques typical of this hacking category.
