Severe Risk
IP 205.210.31.103 is a critical-risk address operating from Google Cloud Platform infrastructure that has accumulated 194 abuse reports over a nine-month window between September 2025 and June 2026, with automated honeypot sensors flagging it exclusively for sustained hacking activity. This IP has been assessed a threat level of 10 out of 10, reflecting the volume and persistence of its hostile connections.
Analysis of the 194 reports reveals that all 20 recent threat-category attributions classify the activity as hacking, with honeypot detections consistently capturing attack connection attempts. The sensor data includes Suricata alerts identifying broken acknowledgment packets in TCP streams, suggesting the attacker employs packet manipulation techniques likely aimed at evading detection or exploiting stateful inspection weaknesses. All detections originated from automated honeypot infrastructure, yielding an 80 percent confidence rating. The nine-month reporting span from September 2025 through June 2026 indicates persistent, ongoing threat activity from this US-based address on Google's cloud network rather than opportunistic scanning.
The dominant hacking category encompasses intrusion attempts, vulnerability exploitation and unauthorized access vectors. Broken acknowledgment packets in TCP streams commonly indicate reconnaissance behaviour, firewall evasion attempts or exploitation of TCP protocol implementation flaws. These techniques can enable session hijacking, service disruption or initial access pathways for subsequent payload delivery. The sustained nature of reports over an extended period suggests this IP is controlled by a determined adversary rather than opportunistic scanning tooling.
Site operators should immediately block or heavily restrict traffic from 205.210.31.103 at the network perimeter, implement strict ingress filtering and employ fail2ban or similar tools to dynamically ban repeated offenders. Ensuring Suricata or equivalent intrusion detection systems have updated rulesets will improve detection of malformed packet patterns. Systems exposed to this address should be audited for unnecessary services, patched against known TCP stack vulnerabilities and monitored for anomalous session behaviour. Implementing TCP stateful inspection with strict sequence number validation can neutralise the broken-ack exploitation vector.
