Severe Risk
IP 103.154.216.188 is a maximum-threat-level address originating from Indonesia that has been linked to 176 abuse reports, predominantly involving SSH brute-force attempts and general hacking activity targeting vulnerable server infrastructure. Despite the low recent activity frequency score, the volume of historical reports and the confirmed hostile intent recorded by automated honeypot sensors establish this address as a serious and persistent threat to any exposed services on the public internet.
The 176 reports attributed to 103.154.216.188 were generated across 20 automated honeypot sensors, with the dominant threat categories being Hacking attempts (16 reports) and SSH brute-force operations (4 reports). The IP traces to AS131111, operated by PT Mora Telematika Indonesia, an Indonesian network provider, and was first and most recently reported during September 2025. The 61% confidence score reflects some uncertainty in attribution, likely due to the shared infrastructure patterns common among automated scanning operations, though the pattern of activity recorded across multiple independent sensors consistently indicates malicious credential-guessing and intrusion attempts rather than legitimate traffic.
SSH brute-force attacks represent one of the most common initial-access vectors used by threat actors to compromise Linux-based servers and network appliances. By rapidly cycling through username and password combinations, attackers operating from addresses like 103.154.216.188 attempt to guess weak or default credentials and gain unauthenticated shell access. Once inside a system, adversaries typically establish persistence, deploy secondary payloads, and move laterally through connected networks. The general hacking category further indicates attempts to probe for additional vulnerabilities beyond SSH, suggesting a broad exploitation strategy rather than a single-targeted approach.
Site operators should treat connections from 103.154.216.188 as definitively hostile and implement immediate blocking at the network perimeter firewall. Deploying fail2ban or equivalent log-based intrusion-prevention tools to automatically ban source IPs after a small number of failed SSH authentication attempts will disrupt brute-force campaigns. Organizations should enforce key-based authentication for all SSH access, disable root login over SSH, and consider moving SSH to a non-standard port to reduce scan surface. Regular auditing of authentication logs and implementation of account lockout policies add additional layers of defense against the credential-guessing tactics observed from this address.
