📊 Threat Analysis
Our monitoring infrastructure has identified 104.28.227.191, geolocated to Los Angeles, United States, operating on the network of Cloudflare, Inc., as a source of suspicious network activity. Our sensors captured 126 malicious requests from this address across a 5-day span, reflecting a sustained attack cadence of ~25.2 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. With 3 different attack patterns detected, this IP exhibits behavior characteristic of advanced automated scanning frameworks. With 50 flagged addresses, United States represents a notable presence in our threat database. At 280/100, 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.

💡 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.
💡 Hacktivism and Ideological Attacks
Hacktivism combines hacking skills with political or social motivations. DDoS campaigns, website defacements, and data leaks target organizations based on ideological disagreements, adding unpredictable threat actors to the landscape.
