Maximum Danger
IP 176.65.149.67 is a maximum-threat-level address operated by Pfcloud UG under AS51396 in the Netherlands that has generated 5,089 abuse reports across automated honeypot sensors over approximately eleven months, making it one of the most persistently hostile IPs documented in recent community threat feeds. With a threat score of 10 out of 10 and an activity frequency rating of 8 out of 10, this address represents a sustained, high-volume intrusion threat targeting exposed network services.
Detection data spanning August 2025 through July 2026 reveals consistent offensive behavior, with all 5,089 reports categorizing the activity under general hacking attempts including unauthorized access attempts and exploitation of vulnerabilities. Honeypot sensors detected the address repeatedly, with alert signatures matching established threat indicators such as SSH sessions initiated on non-standard ports — a technique frequently employed to evade basic port-based filtering and conceal credential brute-forcing or session hijacking attempts. The 87% confidence score indicates high certainty that this activity originates from deliberate malicious intent rather than misconfiguration or benign scanning.
The dominance of hacking-category activity suggests systematic probing for vulnerabilities in publicly accessible services, particularly Secure Shell implementations that may be running on atypical ports to avoid casual reconnaissance. Such activity elevates risk for any exposed SSH, Telnet, or administrative interfaces, as sustained brute-force campaigns can eventually compromise weak credentials, while unusual-port SSH traffic may indicate use of custom attack tooling designed to bypass standard network monitoring. Organizations with internet-facing management interfaces face elevated exposure when this address is not blocked at the network perimeter.
Defensive measures should include immediate blocking of this IP address at the firewall or network edge, implementation of fail2ban or similar dynamic blocking tools to respond to repeated authentication failures, and migration of administrative services to non-standard ports with strong multi-factor authentication enforcement. Regular monitoring of authentication logs for source IPs matching this address range and implementation of strict allowlisting for inbound management traffic will further reduce exposure to similar threats in the future.
