Severe Risk
IP 66.132.153.61 is flagged as a critical-risk address with a threat level of 10 out of 10, linked to sustained hacking activity including intrusion attempts and exploitation of vulnerabilities against exposed services. This United States-based IP has accumulated 1,298 abuse reports through automated honeypot sensors, making it one of the most reported addresses in recent threat-intelligence feeds. The IP operates within AS398324 under CENSYS-ARIN-01, and the sustained volume of reports spanning August 2025 through March 2026 indicates persistent scanning and attack behaviour over a multi-month period.
Automated honeypot sensors across multiple networks logged all 20 most recent threat-category reports categorizing the activity as general hacking attempts. With a confidence score of 68%, the attribution to malicious intent is substantial though not absolute, allowing for the possibility that some connections may originate from misconfigured scanners or transit traffic passing through this address. The network operator CENSYS-ARIN-01 is associated with internet scanning infrastructure, which can sometimes produce overlapping detection signatures that inflate report counts for adjacent addresses.
The dominant hacking classification encompasses a broad spectrum of intrusion techniques, including attempts to exploit unpatched services, brute-force authentication attacks, and reconnaissance probes designed to map vulnerable entry points. For any organisation exposing SSH, Telnet, HTTP interfaces, or database services to the internet, an address with this many reported connections represents a concrete risk of credential compromise or exploitation of known vulnerabilities. Even a small success rate across thousands of attempts can yield significant unauthorized access.
Site operators should block or rate-limit this IP at the network edge firewall and implement fail2ban or similar dynamic blocking tools to automate defensive responses. Enforcing key-based authentication for remote access services, disabling unused administrative interfaces, and maintaining strict patch cycles for exposed software drastically reduces the effectiveness of such intrusion attempts. Continuous monitoring of authentication logs for repeated failed login patterns from this address and similar sources will help identify ongoing targeting campaigns.
