📊 Threat Analysis

Threat intelligence analysis has linked 18.228.155.148 to malicious activity originating from São Paulo, Brazil, operating on the network of Amazon Technologies Inc.. The address has been under observation since its initial detection. During its 1-day observation window, we recorded 37 hostile requests from this IP — roughly 37 per day on average. Classified as a hosting IP, this address likely runs on a rented server or cloud instance. Attackers prefer datacenter IPs for their high bandwidth and disposable nature. The dual attack vectors of Request Flooding combined with User-Agent Anomaly indicate a coordinated assault rather than opportunistic scanning. Brazil currently accounts for 102 blocked IPs in our database, making it a significant source of malicious traffic. At 263/100, this is an extremely high-risk address. All traffic should be considered hostile.

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.

💡 Subdomain Takeover Vulnerabilities

Subdomain takeover occurs when DNS records point to decommissioned services. Attackers claim the abandoned resource and serve content under the trusted domain, enabling cookie theft, phishing, and reputation damage.
