Threat intelligence analysis has linked 46.21.253.87 to malicious activity originating from Moscow, Russia, operating on the network of Start2 LLC. The address has been under observation since its initial detection. During its 2-day observation window, we recorded 100 hostile requests from this IP — roughly 50 per day on average. 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. Rate-based attacks from this IP aim to overwhelm server resources through high-volume request flooding. Our records show 101 malicious IPs originating from Russia, positioning it as a significant contributor to global threat activity. At 70/100, this IP warrants immediate defensive action.
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.
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.
WordPress sites face constant automated attacks targeting xmlrpc.php for brute force amplification, wp-login.php for credential theft, and vulnerable plugins for remote code execution. Over 90% of CMS-based attacks specifically target WordPress installations.
