📊 Threat Analysis

IP address 176.52.25.87 has been traced to Kazan', Russia, operating on the network of "MTS" OJSC. Our threat detection systems have flagged this address based on observed malicious behavior patterns. Our sensors captured 315 malicious requests from this address across a 4-day span, reflecting a sustained attack cadence of ~78.8 requests per day. The address is classified as residential, meaning it likely belongs to an end-user ISP connection. Malicious activity from residential IPs typically indicates device compromise or botnet membership.

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.

💡 Behavioral Analysis vs Signature Detection

Signature-based detection matches known attack patterns but misses novel threats. Behavioral analysis identifies anomalies in request patterns, timing, and volume, catching zero-day attacks that signatures cannot recognize.
