📊 Threat Analysis

Threat intelligence analysis has linked 212.30.36.11 to malicious activity originating from Nuremberg, Germany, operating on the network of GSL Networks Pty LTD. The address has been under observation since its initial detection. During its 23-day observation window, we recorded 19 hostile requests from this IP — roughly 0.8 per day on average. This residential IP is likely a compromised consumer device. Home routers and IoT equipment with default credentials are prime targets for botnet operators. The dual attack vectors of Path Enumeration combined with User-Agent Anomaly indicate a coordinated assault rather than opportunistic scanning. With 151 flagged addresses, Germany represents a significant presence in our threat database. With a threat score of 100/100, this IP is among the most dangerous addresses in our database. Immediate and complete blocking is strongly recommended.

This IP is classified as residential, suggesting it may belong to a compromised home device, IoT botnet member, or an infected personal computer. Residential IPs involved in attacks often indicate malware infection without the owner's knowledge.

Security Intelligence

💡 API Abuse and Enumeration

Modern attacks increasingly target APIs rather than traditional web interfaces. Attackers enumerate endpoints, test for broken authentication, and exploit excessive data exposure. API attacks are harder to detect as they mimic legitimate programmatic access patterns.

💡 Data Center IP Reputation

IPs originating from data centers and hosting providers account for a disproportionate amount of malicious traffic. Compromised VPS instances, bulletproof hosting, and abused trial accounts create persistent attack infrastructure that can be difficult to shut down.
