📊 Threat Analysis

42.113.129.65 is registered in Phụng Nghia, Vietnam, operating on the network of FPT Telecom Company. This IP first appeared in our threat feeds after triggering multiple behavioral detection signatures. Our sensors captured 162 malicious requests from this address across a 4-day span, reflecting a sustained attack cadence of ~40.5 requests per day. Classified as a VPN or proxy server, this IP serves as an anonymization layer. While VPNs have legitimate uses, this address has been observed routing clearly malicious traffic. The dual attack vectors of Path Enumeration combined with User-Agent Anomaly indicate a coordinated assault rather than opportunistic scanning. Vietnam currently accounts for 1,189 blocked IPs in our database, making it a major source of malicious traffic. At 130/100, this is an extremely high-risk address. All traffic should be considered hostile.

This IP is associated with a VPN or proxy service. Attackers frequently route their traffic through anonymizing services to obscure their true location. This makes attribution more challenging but the malicious behavior patterns remain detectable.

Security Intelligence

💡 Prototype Pollution Attacks

Prototype pollution manipulates JavaScript object prototypes to inject properties that affect all objects in an application. This can lead to denial of service, property injection, and in some cases remote code execution in Node.js applications.

💡 Deception Technology Beyond Honeypots

Modern deception technology deploys fake credentials, decoy files, and breadcrumbs throughout production environments. When attackers interact with these deceptions, high-fidelity alerts trigger with virtually zero false positives.
