Elevated Risk
IP 46.151.182.220, registered to OPTIBOUNCE and operating within Netherlands network AS214967, presents a high-risk threat profile with a threat level of 8/10 and a confidence score of 94%, according to automated honeypot sensors that logged 205 total abuse reports over a four-month observation window from February through May 2026. The address demonstrates a concentrated focus on SSH-based intrusion activity, with hacking and SSH attack categories each accounting for the full volume of recent reports, indicating a persistent but targeted automated assault campaign against exposed SSH services.
The detection data reveals that automated honeypot sensors across multiple vantage points identified this IP as the source of repeated SSH brute-force attempts, recording 25 and 50 violations respectively in separate enforcement events, alongside alerts for SSH sessions established on unusual non-standard ports. With 20 separate honeypot sensor sources contributing reports, the activity pattern spans the full February-to-May 2026 timeframe, suggesting sustained rather than opportunistic engagement. Despite the moderate activity frequency rating of 2/10, the consistent volume of abuse reports and the high confidence attribution indicate that this IP represents a known, persistent threat actor within the Dutch hosting infrastructure represented by OPTIBOUNCE's ASN.
SSH brute-force attacks represent one of the most common initial-access vectors deployed against internet-exposed servers, where automated tools systematically attempt credential combinations to compromise accounts with weak or default passwords. The detection of sessions on unusual ports suggests the operator may be attempting to evade standard security monitoring by running SSH services on non-standard ports, a technique often used to bypass naive firewall rules while maintaining the protocol's encrypted tunnel for subsequent lateral movement. For any organization exposing SSH to the internet, this activity poses a concrete risk of unauthorized server access, data exfiltration, or use of compromised infrastructure as a pivot point for further attacks.
Site operators should implement immediate defensive measures including SSH key-based authentication to eliminate password-based credential guessing, relocating the SSH service to a non-standard port to reduce automated scanning exposure, and deploying fail2ban or similar intrusion-prevention tools to automatically block IPs exhibiting brute-force patterns. Network-level blocking of this IP address based on its established abuse reputation provides an additional layer of protection, while monitoring for any successful authentication anomalies remains critical given the sustained nature of the observed threat activity against SSH targets.
