Extreme Threat
IP 125.163.139.181 is a critical-risk address originating from Indonesia that has been flagged as an exploited host by automated honeypot sensors, with a threat level of 10 out of 10 based on 3,148 total abuse reports. The IP operates within AS7713, managed by PT Telekomunikasi Indonesia, and was first and most recently reported in January 2026, indicating a concentrated period of malicious activity originating from this compromised infrastructure.
The volume of reports associated with IP 125.163.139.181 is substantial, placing it among the most frequently reported addresses in the threat intelligence corpus. All 3,148 reports were generated by automated honeypot sensors, lending consistency to the detection methodology, though the 62% confidence score suggests some uncertainty regarding the precise nature or attribution of the hostile activity. The reported category of "Exploited Host" indicates that this IP address belongs to a system that has been compromised and is now being weaponized by threat actors to conduct further attacks, likely without the knowledge or consent of the original owner. The network operator, PT Telekomunikasi Indonesia, operates one of Indonesia's largest telecommunications infrastructures, meaning this exploited host sits within a high-capacity network capable of amplifying attack traffic.
An exploited host represents a significant threat to internet security because the compromised machine serves as a proxy for malicious activity, obscuring the true source of attacks and potentially bypassing reputation-based filtering that would normally block known malicious sources. Attackers leverage such hosts to launch distributed attacks, scan for vulnerabilities, distribute malware payloads, or conduct reconnaissance, all while the legitimate operator bears the reputational and legal risk of having their infrastructure used for harmful purposes. The concentration of 3,148 reports on a single IP within a narrow timeframe underscores the aggressive nature of the compromise and the immediate danger this address poses to any exposed service.
Site operators should immediately block IP 125.163.139.181 at the network perimeter and monitor logs for any associated scanning or exploitation attempts. Deploying fail2ban or equivalent intrusion prevention tools can automate the blocking of repeated malicious connection attempts. Organizations should ensure all systems on their network are monitored for outbound connections to this address, as those within the same network segment may themselves be compromised. Finally, consider filing an abuse report with PT Telekomunikasi Indonesia using their standard routing contact procedures to alert the provider that one of their subscriber addresses is hosting malicious activity.
