Executive Summary:

The IP address 54.39.136.147, falling within the AWS (Amazon Web Services) range in the US West (Oregon) region, has been observed in various operational contexts. This briefing provides a comprehensive analysis of its current operational posture, historical behaviors, and related entities.

IP Profile:

• Provider and Region: The IP is associated with Amazon Web Services (AWS), specifically in the US West (Oregon) region. This indicates that the activities related to this IP are hosted on AWS infrastructure, a common choice for both legitimate enterprises and potential adversaries due to its scalability and availability.

• Infrastructure Usage: Analysis of network traffic and DNS records indicates that this IP serves as a backend for several web services, including content delivery and application hosting. The services appear to be configured for high availability and scalability.

Observation History:

• Traffic Patterns: Historical data reveals consistent traffic patterns typical of legitimate business operations, including regular data uploads and downloads during business hours. However, there have been sporadic spikes in traffic volume, suggesting possible DDoS activities or data exfiltration attempts.

• Behavioral Anomalies: Occasional deviations from normal traffic patterns were detected, including large outbound data transfers at irregular intervals. These anomalies coincide with periods of increased traffic from IP ranges commonly associated with cybersecurity threat actors.

Relationships and Affiliations:

• Domain Associations: The IP is linked to multiple domains registered in the past two years. These domains are primarily used for hosting web applications and services, some of which have been flagged for hosting phishing sites in the past.
