Severe Risk
IP 66.132.153.55 is a critical-risk address with a 10/10 threat level and 1191 abuse reports spanning August 2025 to March 2026, predominantly linked to active hacking activity including intrusion attempts and exploitation of vulnerabilities against exposed services.
Automated honeypot sensors recorded 20 recent hacking-category reports against this US-based IP operating within AS398324 (CENSYS-ARIN-01), yielding a 69% confidence score in the attribution. Despite the extremely high threat rating and substantial report volume, the activity frequency metric registers at 0/10, suggesting either episodic targeting patterns or that the bulk of historical reports stem from legacy encounters rather than sustained current operations. The IP's registration under a US-based ASN operator places its origin within North American network infrastructure, though this geographic context offers limited predictive value regarding the actor's true location or intent.
The dominant hacking classification encompasses general intrusion activity such as vulnerability probing, brute-force authentication attempts, and exploitation of misconfigured services left accessible on the internet. While activity frequency may appear low at present, the accumulated report history demonstrates persistent targeting of internet-facing systems, and each new report signals renewed interest from automated attack tooling. Real-world risk manifests when organizations expose services with weak credentials, unpatched software, or default configurations that these scanning campaigns systematically catalogue and exploit.
Site operators should treat this IP as high-risk and implement defensive controls accordingly: enforce strong, unique credentials on all internet-facing services, apply security patches promptly, and deploy rate-limiting mechanisms such as fail2ban to disrupt automated attack patterns. Blocking or severely restricting inbound access from untrusted networks, monitoring authentication logs for unusual source patterns, and leveraging network-level threat intelligence feeds can further reduce exposure to probing activity from this address.
