📊 Threat Analysis

Threat intelligence analysis has linked 89.117.104.21 to malicious activity originating from Frankfurt, Germany, operating on the network of Cyberzone S.A.. The address has been under observation since its initial detection. During its 1-day observation window, we recorded 12 hostile requests from this IP — roughly 12 per day on average. The address operates as a VPN/proxy exit node. Attackers route traffic through anonymizing services to obscure their real location and evade IP-based security controls. The dual attack vectors of Path Enumeration combined with Request Flooding indicate a coordinated assault rather than opportunistic scanning. With 110 flagged addresses, Germany represents a significant presence in our threat database. At 115/100, 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.

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.

💡 TLS Fingerprinting (JA3/JA4)

TLS fingerprinting creates unique identifiers based on how clients negotiate encrypted connections. The JA3 and JA4 methods generate hashes from TLS ClientHello parameters, enabling identification of specific tools and malware regardless of IP address changes.
