Substantial Risk
IP 165.154.120.13 is a high-risk address assessed at a maximum threat level of 10/10, linked to sustained hacking activity including unauthorized access attempts and intrusion operations. With 170 abuse reports filed against this single IP over an eight-month window spanning November 2025 through June 2026, the address has demonstrated persistent malicious behavior that warrants immediate blocking by exposed network operators.
Analysis of the available intelligence reveals that all 170 reports originated from automated honeypot sensors, with a consistent volume of hacking-category threat reports filed throughout the observation period. The activity frequency rating of 6/10 indicates regular, recurring attack patterns rather than isolated probing. Geographically, the IP routes through Thailand via AS135377, operated by UCLOUD INFORMATION TECHNOLOGY HK LIMITED, an infrastructure provider whose network appears to be actively abused for hostile reconnaissance and exploitation attempts. The confidence score of 79% reflects strong evidentiary support for the assessed threat classification, though operators should note that this figure leaves room for limited legitimate traffic ambiguity.
The dominant threat category, hacking, encompasses a broad spectrum of intrusion methodologies including vulnerability exploitation, credential attacks, and unauthorized system access attempts. The specific attack pattern noted, repeated connection attempts from this source, suggests automated tooling designed to identify and compromise exposed services. Real-world risk manifests as potential account compromise, data exfiltration, or pivoting from compromised endpoints into broader network infrastructure. Any service with exposed authentication interfaces or unpatched vulnerabilities faces elevated risk when accessible to this address.
Site operators should implement immediate defensive measures including IP-based blocking at the firewall or WAF layer, supplemented by rate-limiting on authentication endpoints to mitigate brute-force attempts. Deploying intrusion detection systems and implementing strict authentication policies such as key-based authentication and multi-factor authentication substantially reduces exploitability. Regularly reviewing access logs for connection attempts from this address and similar high-threat sources helps maintain situational awareness. Proactive threat intelligence consumption and automated blocking based on reputation feeds provides ongoing protection without manual intervention.
