📊 Threat Analysis

Threat intelligence analysis has linked 45.3.33.78 to malicious activity originating from Ashburn, United States, operating on the network of 3xK Tech GmbH. The address has been under observation since its initial detection. The address has been active for 19 days in our monitoring system, producing 289 flagged requests at a rate of ~15.2/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. Detected suspicious User-Agent anomalies including empty, forged, or rapidly rotating UA strings — characteristic of automated scanning tools. United States currently accounts for 151 blocked IPs in our database, making it a significant source of malicious traffic. At 130/100, this is an extremely high-risk address.

Security Intelligence

💡 File Upload Vulnerabilities

Insecure file upload functionality allows attackers to upload web shells, malware, or scripts that execute on the server. Proper validation must check file content, not just extensions, and uploaded files should be stored outside the web root.

💡 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.
