Severe Risk
IP 205.210.31.235 is a critical-risk address operated within Google's cloud infrastructure that has accumulated 165 abuse reports over approximately eleven months, making it one of the most persistently reported endpoints in recent threat intelligence feeds. The IP earned a perfect 10/10 threat level rating with an 84% confidence score, indicating a highly reliable assessment that this address is actively engaged in malicious scanning and intrusion activity rather than coincidental traffic. With an activity frequency rated 8/10, this is not an isolated incident but rather a sustained campaign targeting exposed services across the internet.
Detection data from 20 automated honeypot sensors across the security community confirms that this IP has been consistently active between August 2025 and June 2026, with the vast majority of recent reports categorizing the activity as general hacking attempts. The network ownership by Google-Cloud-Platform (ASN AS396982) is significant because cloud infrastructure IP addresses are frequently leveraged by threat actors to disguise their origin and benefit from the reputation of major technology providers. Suricata intrusion detection systems specifically flagged broken acknowledgment packets during probe attempts, suggesting the attacker uses sophisticated stateful scanning techniques designed to evade basic firewall rules and map live hosts for subsequent exploitation.
The dominance of hacking-category reports indicates that this IP is engaged in systematic reconnaissance and vulnerability probing rather than opportunistic noise. The "web app/probe" notation alongside Suricata alerts reveals that the operator is actively testing web-facing applications for exploitable conditions, including potential OWASP Top 10 vulnerabilities such as injection flaws, broken authentication, or sensitive data exposure. The broken ACK pattern observed is consistent with TCP fingerprinting techniques used to identify firewall rule sets or operating system characteristics before launching targeted attacks, meaning defenders should treat any traffic from this address as a precursor to more serious compromise attempts.
Site operators should immediately block IP 205.210.31.235 at the firewall or load balancer level, as allowing continued inbound communication provides attackers with an ongoing reconnaissance opportunity. Implementing rate-limiting rules on authentication endpoints and deploying fail2ban or equivalent log-analysis tools can automatically ban repeated suspicious requests. Web application firewalls should be configured to detect and block probing patterns associated with application scanning. Finally, maintaining strict logging of all inbound connections from this address will support incident response efforts if a related compromise is discovered on your infrastructure.
