Extreme Threat
IP 117.176.131.211 is a critical-risk address linked to sustained SSH brute-force attacks, originating from China Mobile Communications Group Co., Ltd. operating AS9808 in China. With a threat level of 10/10, a 98% confidence score, and 252 total abuse reports logged by automated honeypot sensors, this IP represents an active, high-volume intrusion threat. The address was first reported in January 2026 and remained active through May 2026, indicating persistent malicious behavior over at least four months. The dominant threat category is SSH-based intrusion activity, supplemented by general hacking attempts, making this IP a clear candidate for immediate blocking by any organization running exposed SSH services.
Detection data from 20 independent honeypot sensors reveals concentrated attack activity focused on SSH services, with evidence of multiple concurrent brute-force campaigns. Analysis of sanitized attack-pattern logs shows 50 violations recorded through automated defensive tools, including repeated sshd authentication failures consistent with systematic password-guessing campaigns. Notably, detection systems also captured an SSH session in progress on an unexpected port, suggesting that either successful authentication may have occurred or the attacker was probing for vulnerable configurations. The eight out of ten activity-frequency rating confirms this is not an isolated incident but a sustained, automated campaign operating across multiple targets.
SSH brute-force attacks remain one of the most common initial-access vectors in network intrusion, where automated tools systematically attempt credential combinations until access is granted to a target server. The concentration of 252 reports specifically targeting SSH infrastructure indicates this IP participates in large-scale credential-stuffing operations, likely running wordlist-based or dictionary attacks against exposed endpoints. Real-world risk includes unauthorized server access, data exfiltration, lateral movement within networks, and deployment of secondary payloads such as backdoors or cryptocurrency miners. Organizations with internet-facing SSH services are the primary targets of this activity pattern.
Site operators should immediately block 117.176.131.211 at the firewall or network edge to eliminate this threat vector. Deploy key-based authentication exclusively and disable password-based SSH login to render brute-force attempts ineffective. Implementing fail2ban or equivalent automated banning tools will dynamically block IPs exhibiting brute-force behavior patterns. Additional hardening measures include changing the default SSH port to reduce automated scanning, disabling direct root login, and enforcing strong passphrase policies. Continuous monitoring of authentication logs combined with intrusion detection signatures for repeated failed-login patterns will provide early warning of similar threats.
