Substantial Risk
IP 205.210.31.168 is a critical-risk address associated with 189 reported incidents of malicious activity originating from Google Cloud Platform infrastructure in the United States, with a dominant threat profile centered on hacking intrusion attempts and reconnaissance scanning.
Over approximately eight months of reporting activity between October 2025 and June 2026, this IP generated abuse reports across 20 distinct automated honeypot sensors. The majority of recent reports catalogue hacking activity, alongside isolated port scan reconnaissance and exploited host indicators. Network analysis traces this traffic to AS396982, operated by Google Cloud Platform, suggesting the address may represent either a compromised cloud resource or infrastructure deliberately leveraged for offensive operations. The 76% confidence score reflects strong but not absolute attribution certainty given the shared nature of cloud IP ranges.
The hacking activity detected against this address reflects active intrusion attempts, exploitation of vulnerabilities targeting exposed services, and unauthorized access probing. Port scan indicators align with pre-attack reconnaissance designed to identify open entry points on target systems. Suricata sensor data notes malformed packet signatures consistent with port scan and exploit delivery patterns. The exploited host classification raises the possibility that this Google Cloud IP represents a compromised virtual machine being weaponized as an attack platform without the legitimate operator's knowledge, a common scenario in cloud environments where stolen or poorly secured credentials grant attackers operational infrastructure.
Network defenders should block 205.210.31.168 at firewall and IDS layers given its maximum threat rating. Implementing fail2ban or equivalent dynamic blocking tools on internet-facing services such as SSH and web applications automates hostile connection termination. Regular patching of exposed software eliminates vulnerabilities these attacks attempt to exploit. Monitoring inbound traffic from cloud infrastructure ranges helps identify systematic reconnaissance patterns before exploitation occurs. If connections to your services are observed, retaining firewall logs and considering a report to Google Cloud Platform's abuse team supports broader community defense.
