Request FloodingUser-Agent Anomaly

📊 Threat Analysis

Our monitoring infrastructure has identified 104.23.166.124, geolocated to Amsterdam, Netherlands, operating on the network of Cloudflare, Inc., as a source of suspicious network activity. During its 13-day observation window, we recorded 340 hostile requests from this IP — roughly 26.2 per day on average. 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 Request Flooding combined with User-Agent Anomaly indicate a coordinated assault rather than opportunistic scanning. Our records show 2,847 malicious IPs originating from Netherlands, positioning it as a major contributor to global threat activity. A score of 160/100 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

💡 DDoS Mitigation Approaches

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.

💡 Multi-Factor Authentication Importance

MFA dramatically reduces the effectiveness of credential-based attacks. Even when passwords are compromised through phishing or data breaches, the additional authentication factor prevents unauthorized access in the vast majority of cases.
