High Risk
IP address 45.183.247.34 is a high-risk address associated with SSH brute-force attack activity, with a threat level rated at 8 out of 10 and 323 total abuse reports filed against it through automated honeypot sensors between August and November 2025.
The address, registered to GRUPO LUMA SAS in Colombia under autonomous system number AS269777, has generated a substantial volume of incident reports during its active window of approximately four months. The 323 total reports indicate persistent threatening behaviour directed at network infrastructure, with 20 recent reports specifically categorising the activity as SSH-related attack attempts. A confidence score of 68 percent suggests the assessment is well-supported by evidence but allows for the possibility that some benign traffic may have been misclassified. The activity frequency metric of 0 out of 10 likely reflects the temporal distribution of the reports across the four-month period, indicating sustained rather than burst-style engagement with target systems.
SSH brute-force attacks represent a direct pathway to server compromise when organisations rely on password-based authentication. Attackers systematically cycle through credential combinations to guess weak or commonly used passwords, exploiting any exposed SSH service listening on port 22 or alternative ports. Successful authentication grants remote command execution capabilities, enabling data exfiltration, malware deployment or use of the compromised host as a pivot point for deeper network intrusion.
Defensive measures should include immediately deploying key-based authentication and disabling password-based SSH access entirely where feasible. Operators should confirm that fail2ban or equivalent intrusion-prevention tools are actively monitoring authentication logs and auto-banning repeat offenders. Changing the default SSH listening port reduces opportunistic scanning volume, and disabling root login over SSH forces adversaries to compromise an intermediate unprivileged account before attempting privilege escalation. Regular auditing of authentication logs and enforcement of strong password policies on any remaining password-authenticated services will further reduce exposure to this threat category.
