Maximum Danger
IP 176.65.149.27 is a critical-risk address associated with sustained, high-volume SSH intrusion activity originating from Netherlands-based infrastructure operated by Pfcloud UG, with 3,935 abuse reports generated across automated honeypot sensors over a six-month observation window between January and June 2026.
Analysis of the aggregated telemetry from community reports and automated honeypot sensors reveals this address operates with remarkable persistence and volume. The IP scored 8 out of 10 on activity frequency, indicating near-continuous scanning and connection attempts against target systems. The 3,935 total reports concentrated exclusively within the Hacking category demonstrates a singular, focused threat profile rather than opportunistic noise. The 92% confidence score reflects consistent detection patterns across multiple independent sensor types. Network attribution places the hostile traffic within AS51396 operated by Pfcloud UG, a Netherlands-registered hosting provider whose infrastructure has been leveraged for automated intrusion activity during the first half of 2026.
The dominant attack pattern involves Suricata alerts flagging SSH session establishment attempts on non-standard ports, a technique designed to evade detection by targeting servers running Secure Shell services on unconventional ports rather than the default TCP 22. Such probing represents a precursor to credential brute-forcing, private key theft, or exploitation of unpatched SSH daemon vulnerabilities. Servers exposing SSH to the internet face significant risk from this address because the traffic indicates active reconnaissance and repeated authentication attempts that could compromise weak or default credentials.
Site operators should implement automated connection throttling using tools such as fail2ban to block source IPs after repeated authentication failures, enforce key-based authentication exclusively while disabling password-based SSH access entirely, restrict SSH access to known trusted IP ranges through firewall rules, and maintain continuous monitoring of authentication logs for patterns indicative of brute-force activity.
