📊 Threat Analysis

45.3.44.58 is registered in Madrid, Spain, operating on the network of 3xK Tech GmbH. This IP first appeared in our threat feeds after triggering multiple behavioral detection signatures. Over a period of 4 days, this IP generated 76 malicious requests, averaging approximately 19 requests per day. This IP is identified as a VPN or proxy endpoint, commonly used to mask the true origin of attack traffic and bypass geographic or reputation-based blocking. The dual attack vectors of Path Enumeration combined with User-Agent Anomaly indicate a coordinated assault rather than opportunistic scanning. A score of 110/100 places this address in the top tier of severity. Block and investigate any historical connections.

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

💡 Server-Side Request Forgery (SSRF)

SSRF attacks trick servers into making requests to internal resources that should not be publicly accessible. This can expose cloud metadata endpoints, internal APIs, and private network services, potentially leading to full infrastructure compromise.

💡 DNS Amplification Attack Mechanics

DNS amplification exploits open resolvers to reflect and amplify traffic toward victims. A small query triggers a large response directed at the spoofed source IP, achieving amplification factors of 50x or more, overwhelming target bandwidth.
