Maximum Danger
IP 103.120.242.181, allocated to VNPT Corp under ASN AS45899 in Vietnam, presents a severe security risk with a threat level of 10 out of 10 based on 2917 abuse reports generated through automated honeypot sensors in November 2025. The dominant threat activity involves SSH brute-force attempts targeting exposed Secure Shell services.
The volume of malicious activity originating from this address is substantial, with 2917 distinct incident reports submitted to the security community. Detection occurred across 20 separate automated honeypot installations, confirming the IP's persistent engagement with SSH authentication mechanisms. All reported activity falls within November 2025, indicating a concentrated campaign rather than scattered opportunistic probing. While the activity frequency score of 0 out of 10 suggests periodic rather than continuous engagement, the sheer number of individual attempts demonstrates deliberate, sustained effort to compromise target systems.
SSH brute-force attacks represent a direct pathway to server compromise when successful. Attackers systematically iterate through username and password combinations to guess valid SSH credentials, exploiting weak or default passwords on internet-facing systems. Once authenticated, threat actors can establish persistent backdoor access, exfiltrate sensitive data, deploy cryptocurrency miners or pivot further into compromised infrastructure. The confidence score of 59 percent indicates a reliable correlation between this IP and the reported malicious behaviour, though some attribution uncertainty remains.
Operators maintaining publicly accessible SSH services should immediately implement defensive measures to mitigate this threat. Deploying fail2ban or equivalent authentication-failure monitoring tools enables automatic temporary IP blocking after repeated failed login attempts. Switching from password-based to public key authentication eliminates the primary attack vector entirely. Changing the default SSH port reduces exposure to automated scanning tools, and disabling direct root login forces attackers to compromise a standard user account first. Regular monitoring of authentication logs for this IP address and implementation of network-level rate limiting provide additional layers of defence against credential-guessing campaigns.
