Critical Alert
IP address 45.148.10.183 is a high-risk Dutch address assessed at threat level 10/10, linked predominantly to sustained SSH brute-force attacks and widespread exploitation of exposed SSH services. With 1,785 abuse reports generated over approximately three months in 2026 and a 96% confidence rating, this IP represents one of the most consistently malicious hosts observed by automated honeypot sensors in recent periods. Its activity frequency score of 8/10 confirms near-continuous offensive operations rather than isolated probing.
Detection data from 20 independent automated honeypot sensors document a clear pattern: repeated SSH brute-force attempts, multiple confirmed SSH sessions established on expected ports, and evidence that the attacking host has successfully exploited at least some targeted SSH services. Fail2ban logs on remote blocklist nodes recorded at least five failed authentication attempts attributable to this address, while Suricata intrusion-detection alerts repeatedly flagged the same SSH brute-force behaviour on standard ports. The AS48090 network operated by Techoff Srv Limited in the Netherlands hosts infrastructure that has generated report volumes far exceeding typical scanning activity, indicating deliberate, high-volume credential-attack campaigns rather than opportunistic sweeps.
SSH brute-force attacks systematically cycle through username and password combinations to gain unauthorized shell access to servers. When successful, an attacker obtains full command-line control, enabling data theft, lateral movement through internal networks, deployment of persistent backdoors, and integration of the compromised host into botnets for further attacks. The presence of confirmed "exploited host" events in the report data for 45.148.10.183 indicates that this IP has not merely attempted access but has achieved compromise of at least some target systems, amplifying its risk profile considerably beyond a simple scanning address.
Site operators running publicly accessible SSH services should treat any authentication activity from 45.148.10.183 as hostile. Immediate blocking at the firewall or network edge is strongly advised. Beyond blocking, operators should enforce key-based authentication and disable password-based SSH login entirely where feasible, change the default SSH port to reduce automated targeting, and implement fail2ban or equivalent rate-limiting rules to throttle repeated authentication failures. Multi-factor authentication adds a critical additional barrier that defeats credential-stuffing campaigns regardless of password strength. Keeping SSH daemons patched and monitoring for any unexpected SSH sessions from this address will further reduce exposure to this threat.
