Severe Risk
IP 94.154.35.215 is a maximum-threat-level address originating from the Netherlands, operated by Railnet LLC under ASN AS214943, that has been flagged 7,932 times across automated honeypot sensors since January 2026, with its activity peaking at an 8/10 frequency through July 2026. The dominant threat profile consists of SSH brute-force attacks and active SSH session exploitation attempts, supported by secondary hacking reconnaissance activity and evidence that the IP may itself function as an exploited host being weaponized without its operator's knowledge.
The report volume of 7,932 incidents across 20 independent honeypot sensors gives this address a confidence rating of 85%, indicating a highly consistent and sustained pattern of malicious behavior over a seven-month observation window. Suricata intrusion-detection signatures specifically captured ET INFO alerts documenting active SSH sessions established on expected ports, alongside repeated SSH brute-force attempt signatures, confirming the IP's systematic targeting of Secure Shell services. The "Exploited Host" classification in recent reports suggests this address may represent a compromised infrastructure node rather than a deliberately provisioned attack platform, though the operational intent remains identical regardless of ownership status.
SSH brute-force attacks pose a concrete threat to any internet-exposed server running default or weakly credentialed SSH daemons, as successful authentication grants attackers persistent command-line access, lateral movement capability and the ability to deploy secondary payloads. The detection of active SSH sessions indicates that brute-force attempts have progressed beyond the probing stage, implying either successful authentication or the presence of an established backdoor. When combined with the broader hacking activity profile, this IP represents a versatile intrusion tool capable of automated vulnerability scanning, credential stuffing and post-compromise exploitation phases.
Site operators should immediately block IP 94.154.35.215 at the network perimeter or firewall level and implement fail2ban or equivalent log-based authentication failure monitoring to auto-ban repeated SSH login attempts. All SSH services should enforce key-based authentication exclusively, disable root login and consider moving default port 22 to a non-standard alternative. Regular audit of authentication logs for source IPs in the AS214943 range, combined with automated alerting on unusual session behavior, will help detect any attempted reconnections or probing of other exposed services.
