Path EnumerationRequest Flooding

📊 Threat Analysis

36.106.166.13 is registered in Tianjin, China, operating on the network of ASN for TIANJIN Provincial Net of CT. This IP first appeared in our threat feeds after triggering multiple behavioral detection signatures. Our sensors captured 53 malicious requests from this address across a 2-day span, reflecting a sustained attack cadence of ~26.5 requests per day. The address is classified as residential, meaning it likely belongs to an end-user ISP connection. Malicious activity from residential IPs typically indicates device compromise or botnet membership. The dual attack vectors of Path Enumeration combined with Request Flooding indicate a coordinated assault rather than opportunistic scanning. China currently accounts for 2,899 blocked IPs in our database, making it a major source of malicious traffic. At 85/100, this IP warrants immediate defensive action.

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

💡 DDoS Mitigation Approaches

Distributed denial of service attacks overwhelm infrastructure with traffic volume. Effective mitigation combines always-on traffic scrubbing, anycast network distribution, rate limiting, and the ability to quickly scale absorption capacity during attacks.

💡 IPv6 Scanning Challenges

The vast IPv6 address space makes traditional sequential scanning impractical. However, attackers use DNS records, certificate transparency logs, and predictable address patterns to identify active IPv6 hosts, adapting their techniques to the expanded address space.
