Severe Risk
IP address 172.86.66.146 is a critical-risk address operating from German network infrastructure under AS14956 (ROUTERHOSTING), with 330 accumulated abuse reports and a maximum threat score of 10/10 indicating severe malicious activity. All recent detections consistently flag unauthorized hacking attempts, placing this IP squarely in the highest-risk category for any exposed service. The concentration of reports against automated honeypot sensors demonstrates sustained, deliberate targeting of internet-facing systems rather than incidental scanning.
Analysis of the available data reveals a substantial volume of hostile activity originating from this German-hosted address during November 2025. The 330 total reports correlate with confirmed detection across 20 separate honeypot sensors, suggesting the threat actor operates infrastructure capable of widespread scanning or distributes attack payloads across multiple sources. Despite a low activity-frequency metric of 0/10 in recent intervals, the historical report count signals persistent engagement with vulnerable targets over time. The AS14956 autonomous system assignment through ROUTERHOSTING indicates the source resides within a hosting or infrastructure provider environment, a common characteristic for IP addresses involved in automated exploitation campaigns.
The dominant threat classification of hacking encompasses systematic intrusion attempts, vulnerability probing, and unauthorized access campaigns against internet-connected services. This pattern poses concrete risk to any exposed SSH, Telnet, HTTP interfaces, or other network services operated by this IP's targeting scope. Attackers leveraging such infrastructure typically conduct credential stuffing, exploit enumeration, and payload delivery attempts at scale, exploiting unpatched software or misconfigured services to establish persistent footholds. The high confidence score of 74% grounds these assessments in substantial sensor and community reporting data rather than isolated alerts.
Network defenders should treat IP address 172.86.66.146 as definitively hostile and implement immediate blocking at perimeter firewalls or edge routers. Deploying fail2ban, similar log-analysis tools, or web-application firewalls can automatically detect and throttle repeated intrusion patterns from this source. Enforcing strong authentication on all externally accessible services, disabling unused protocols, and maintaining rigorous patch management substantially reduces the attack surface these hacking attempts seek to exploit. Continuous monitoring of authentication logs for sourcing from this address will reveal any successful breach attempts requiring incident response. Organizations operating publicly accessible services should consider reputation-based blocking feeds and threat-intelligence correlation to proactively deny traffic from known high-risk addresses like this one.
