📊 Threat Analysis
Threat intelligence analysis has linked 103.240.99.136 to malicious activity originating from Kolkata, India, operating on the network of Alliance Broadband Services. The address has been under observation since its initial detection. Our sensors captured 376 malicious requests from this address across a 18-day span, reflecting a sustained attack cadence of ~20.9 requests per day. 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. The diversity of 3 separate attack methods suggests a comprehensive attack toolkit — likely an automated scanner that tests for vulnerabilities across multiple categories. India currently accounts for 113 blocked IPs in our database, making it a significant source of malicious traffic. At 165/100, 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.
💡 Watering Hole Attack Strategy
Watering hole attacks compromise websites frequently visited by target organizations. Rather than attacking targets directly, adversaries infect trusted resources, exploiting the inherent trust users place in regularly visited sites.
