Path EnumerationUser-Agent Anomaly

📊 Threat Analysis

The address 58.187.136.64 originates from Hanoi, Vietnam, operating on the network of FPT Telecom Company. It was identified through automated analysis of incoming network traffic across monitored endpoints. Our sensors captured 165 malicious requests from this address across a 14-day span, reflecting a sustained attack cadence of ~11.8 requests per day. 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 1,189 flagged addresses, Vietnam represents a major presence in our threat database. A score of 130/100 places this address in the top tier of severity. Block and investigate any historical connections.

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

💡 Command Injection Techniques

Command injection occurs when attackers insert operating system commands through application inputs. Successful exploitation grants direct server access, enabling data theft, malware installation, and lateral movement across networks.

💡 Network Telescope and Darknet Monitoring

Network telescopes monitor large blocks of unused IP address space. Since no legitimate traffic should reach these addresses, all observed traffic represents scanning, backscatter from spoofed attacks, or misconfiguration — providing pure signal for threat analysis.
