Critical Alert
IP 185.246.128.133 is a high-risk address operated by w1n ltd (AS42237) in Sweden that presents a severe and active threat, scoring a maximum threat level of 10 out of 10 based on 7,085 community and automated honeypot reports recorded between March and July 2026. The IP demonstrates an activity frequency rating of 8 out of 10, indicating sustained and repeated malicious engagement against exposed network services over a four-month period.
Detection data from 20 separate automated honeypot sensors reveals that this address is primarily engaged in SSH brute-force intrusion attempts, with additional evidence of established SSH sessions on expected ports. Suricata alert signatures consistently identify the address as maintaining active SSH connections against honeypot targets, a pattern consistent with credential-guessing campaigns or the establishment of footholds on vulnerable servers. The reported categories include Hacking activity, SSH attacks, and Exploited Host indicators, suggesting the IP may itself be operating from a compromised infrastructure while conducting offensive operations against third parties.
SSH brute-force activity represents one of the most prevalent and effective attack vectors against publicly accessible servers, enabling threat actors to compromise systems through systematic credential guessing. A successful attack can grant unauthenticated access to sensitive data, internal network resources, or the ability to deploy further malicious payloads. The presence of established SSH sessions on this IP indicates that brute-force attempts are not merely automated scanning but have progressed to active session establishment, elevating the risk to any exposed SSH services listening on standard or non-standard ports.
Operators maintaining publicly accessible SSH services should immediately block IP 185.246.128.133 at the network perimeter and implement defensive controls such as fail2ban or similar rate-limiting tools to throttle repeated authentication attempts. Enforcing key-based authentication, disabling root login, and moving SSH to non-standard ports significantly reduces exposure to credential-based attacks. Regular monitoring of authentication logs for patterns associated with this address, combined with timely submission of abuse reports to the network operator, contributes to collective defense against persistent scanning infrastructure.
