Critical Alert
IP 185.243.5.171 is a critical-risk address based in Hong Kong that has generated 427 abuse reports for hacking activity between September and December 2025, with automated honeypot sensors flagging the host as a significant and ongoing threat to exposed network infrastructure worldwide.
The IP operates through AS23470, administered by RELIABLESITE, and has been actively engaged in unauthorized access attempts and intrusion activities according to community and honeypot sources. With a threat level of 10/10 and a 73% confidence score in the assessment, the 427 reports represent sustained malicious behavior observed across a three-month period. The geographic concentration in Hong Kong and the autonomous system operator provide context for the network infrastructure being leveraged to conduct these operations at scale.
Hacking activity encompasses a broad range of intrusion attempts, vulnerability exploitation and unauthorized access vectors that pose concrete risks to exposed services. For organizations with accessible network resources, this IP represents a direct threat of credential compromise, data breach or system infiltration through automated scanning and targeted exploit delivery. The persistent volume of reports indicates the address is actively used within attack infrastructure designed to identify and compromise vulnerable systems globally.
Site operators should block this IP at the firewall or network perimeter level and deploy automated defense tools such as fail2ban to dynamically mitigate repeated intrusion attempts. Enforcing strong, unique credentials alongside multi-factor authentication, maintaining current system patches and deploying intrusion detection systems will substantially reduce exposure to this and similar threat vectors. Continuous monitoring of IP reputation feeds and implementing rate-limiting on exposed authentication endpoints adds further protective depth against automated attack campaigns.
