Maximum Danger
IP address 176.65.149.27 is a high-risk address that has been flagged 4,817 times by automated honeypot sensors over approximately six months in 2026, presenting a critical threat level of 10/10 due to sustained unauthorized access attempts targeting network services.
Located in the Netherlands and operating through AS51396 under Pfcloud UG (haftungsbeschrankt), this IP has generated a substantial volume of abuse reports with an activity frequency rated 8/10, indicating persistent rather than intermittent malicious behavior. All 20 most recent reported threat categories classify the activity as general hacking, specifically unauthorized intrusion attempts. Detection sources consistently identified this address establishing connections that triggered Suricata alerts for SSH sessions on unusual ports, a technique frequently employed to evade standard port-based filtering. With a confidence score of 85%, the detection systems maintain high reliability in attributing these connection attempts to the subject address. The sustained report volume over the January–July 2026 window demonstrates that this activity represents deliberate, ongoing targeting rather than transient scanning.
The dominant threat category, hacking activity involving unauthorized access attempts, poses a concrete risk to any exposed SSH service. Attackers probing non-standard SSH ports typically seek to bypass default firewall rules and automated blocklists that only monitor conventional ports, then attempt credential brute-forcing or exploit known vulnerabilities in outdated SSH implementations. The high report count indicates this address is actively cycling through authentication attempts against targeted systems, increasing the likelihood of success against weak or default credentials. Organizations with exposed SSH services on unconventional ports face elevated risk from such reconnaissance-coupled-with-intrusion patterns.
Site operators should immediately block this IP at the network perimeter firewall and implement fail2ban or similar dynamic denial-of-service tools configured to detect and quarantine repeated SSH connection failures. Enforcing key-based authentication exclusively, disabling password authentication entirely, and restricting SSH access to known administrative subnets substantially reduces vulnerability. Regularly patching SSH daemons and implementing strict connection-rate limiting on all SSH ports, standard and non-standard alike, provides defense-in-depth against this threat category.
