Elevated Risk
IP 118.194.251.145 is a high-risk address originating from Thailand that has been flagged 552 times for malicious activity, with automated honeypot sensors recording sustained hacking probes and SMTP abuse over approximately nine months of observation.
Public abuse reports and automated honeypot detection systems logged this IP across 20 distinct sensor sources, generating 552 total reports between September 2025 and June 2026. The dominant threat category is general hacking activity, accounting for 19 of the most recent logged incidents, while a single report noted email spam behavior involving SMTP abuse. With a threat level rated at 8 out of 10 and a confidence score of 71 percent, this address exhibits a moderate-to-high activity frequency of 5 out of 10. The IP is routed through AS135377, operated by UCLOUD INFORMATION TECHNOLOGY HK LIMITED, a network provider whose infrastructure may be shared with other cloud-based services, complicating reputation-based filtering alone.
The prevalent hacking classification for IP 118.194.251.145 encompasses unauthorized access attempts, vulnerability probing, and intrusion activity that automated honeypot sensors classify as attack connection events. These probes represent real-world exploitation attempts against exposed services, potentially targeting weak authentication mechanisms or unpatched software. The secondary SMTP spam activity observed indicates the IP may also be involved in mass email distribution, whether for advertising, credential phishing, or malware delivery campaigns. Together, these threat patterns suggest a compromised endpoint or a deliberately provisioned scanning and spamming asset operating from this Thai IP address.
Site operators should treat connections from IP 118.194.251.145 as hostile and implement immediate defensive measures. Block or rate-limit access from this address at the firewall level, paying particular attention to exposed services on common attack vectors such as SSH, RDP, HTTP admin panels, and mail submission ports. Enforce strong, unique credentials and consider deploying automated defensive tools such as fail2ban to dynamically ban IPs exhibiting brute-force behavior. Ensure all systems remain current with security patches and employ intrusion detection monitoring to log and alert on any follow-on activity from this source. Email infrastructure administrators should verify SPF, DKIM, and DMARC policies are correctly configured to mitigate any SMTP abuse risk associated with this address.
