Critical Threat
IP 185.11.61.226 is a critical-risk address associated with 903 reported incidents of SSH brute-force intrusion activity, originating from Hong Kong and operated by Chang Way Technologies Co. Limited under ASN AS57523, with automated honeypot sensors recording consistent malicious contact over a compressed January–February 2026 timeframe.
The IP accumulated 903 total abuse reports across 20 distinct honeypot detection points, with the vast majority categorised as general hacking activity alongside six explicit SSH-specific incidents. The aggregate confidence score of 63% reflects moderate attribution certainty typical of anonymised network infrastructure, yet the sheer volume of independent sensor detections creates a compelling threat profile. Geolocation places the source in Hong Kong, and routing through AS57523 identifies a dedicated hosting provider historically associated with transient attack infrastructure. The first reports emerged in January 2026, escalating through February, indicating sustained rather than opportunistic targeting.
SSH brute-force attacks represent a persistent and automated threat vector where adversaries systematically iterate authentication credentials against exposed SSH daemons until valid access is obtained. These attacks exploit weak or default passwords and target any publicly reachable server running SSH on standard or alternate ports. Successful compromise grants lateral movement potential, data exfiltration capability, and the ability to leverage the compromised host as a pivot for further network intrusion. The frequency of such probes across global honeypot networks reflects their effectiveness as a low-cost, high-reward initial access method.
Defenders should immediately block or rate-limit inbound connections from this address at the network perimeter firewall, and audit all SSH-facing services for unnecessary exposure. Implementing key-based authentication exclusively, disabling password-based authentication entirely, and relocating SSH to a non-standard port materially reduces attack surface. Deploying automated dynamic blocking tools such as fail2ban can detect repeated authentication failures and dynamically update firewall rules, while disabling direct root login ensures adversaries cannot escalate privileges with a single valid credential pair.
