Extreme Threat
IP address 115.190.188.197 is a high-risk address operating from Beijing Volcano Engine Technology Co., Ltd. in China, AS137718, that has accumulated 409 abuse reports across automated honeypot sensors between December 2025 and April 2026, with the dominant threat pattern involving SSH brute-force intrusion attempts against exposed servers worldwide.
The IP received a maximum threat score of 10 out of 10 based on 409 total reports submitted by 20 distinct automated honeypot sensors over approximately five months. Detection systems recorded multiple Suricata alerts flagging TCPv4 invalid checksum anomalies alongside numerous Fail2ban log entries documenting sshd violations, with at least one honeypot event capturing the IP engaged in active SSH credential guessing activity. The combination of high report volume and consistent detection across multiple independent sensor sources yields a 63% confidence score, indicating a moderately reliable assessment that this address is operated by an automated attack tool rather than a misconfigured legitimate endpoint.
SSH brute-force attacks represent one of the most common pathways attackers use to gain unauthorized shell access to Linux and Unix servers. Automated attack scripts systematically cycle through username and password combinations, exploiting weak or default credentials to establish persistent backdoor access. Once inside a target environment, threat actors typically deploy cryptocurrency miners, pivot to internal network assets, or exfiltrate sensitive data. The detection of invalid TCP checksums alongside brute-force activity may indicate packet fragmentation techniques designed to evade basic firewall filtering rules.
Administrators should block IP 115.190.188.197 at the network perimeter firewall and implement Fail2ban or similar intrusion prevention tools to automatically ban repeated SSH authentication failures. Enforcing key-based authentication exclusively, disabling root login over SSH, and changing the default port from 22 to a non-standard value substantially reduces exposure to credential-based attacks. Continuous monitoring of authentication logs and deploying intrusion detection signatures for anomalous SSH handshake patterns will further strengthen defensive posture against this threat vector.
