Threat Intelligence Briefing: IP 54.38.147.123/32
Overview:
The IP address 54.38.147.123/32 was observed across various data sources, revealing several key characteristics and associations that are critical for a Security Operations Center (SOC) analyst to consider.
Observation History:
- Geolocation: The IP address is geolocated to the United States, specifically within a data center in Virginia. This aligns with common hosting patterns for cloud services and data centers.
- ASN (Autonomous System Number): The IP is associated with AS16509, which belongs to a major cloud service provider known for hosting a wide array of internet services and platforms.
- Domain Associations: Recent scans identified multiple domain names linked to this IP address, predominantly related to web hosting and cloud services. Some of these domains have a history of short-lived registration, indicative of potentially dynamic content management or temporary services.
- Past Activity: Historical data shows periodic spikes in traffic volume, often correlated with specific domain activity, suggesting episodic or event-driven usage. Notably, a subset of these spikes coincided with the registration of new domains, suggesting the IP could be involved in legitimate yet dynamic cloud service deployments.
Relationships:
- Peer IPs: Analysis of neighboring IP addresses within the same data center reveals a similar pattern of association with cloud service-related domains, suggesting a shared infrastructure environment typical of large-scale hosting facilities.
- Network Traffic Patterns: Traffic analysis indicates that the IP address is involved in both incoming and outgoing communications with a diverse set of external IPs, predominantly within the AS ranges of other cloud service providers and internet service providers. This suggests a high level of integration and interaction with other cloud environments.
Neighborhood Data:
- Infrastructure Context: The neighborhood analysis confirms that this IP is situated within a high-density area of data center infrastructure, surrounded by other IPs serving similar web and cloud-based services. This context supports the conclusion that the IP is part of a robust hosting environment.
Actionable Insights:
1. Monitoring: Given the dynamic nature of domain associations and traffic spikes, continuous monitoring for unusual activity patterns, such as unexpected domain registrations or anomalous traffic volumes, is recommended.
2. Behavioral Baselines: Establish behavioral baselines for traffic patterns associated with this IP to facilitate the detection of deviations that may indicate misuse or compromise.
3. Threat Intelligence Sharing: Engage in threat intelligence sharing with peers to cross-reference observed activities and domain registrations, enhancing the understanding of potential threats linked to this IP.
4. Access Controls: Review and enforce strict access controls and authentication measures for services hosted on this IP, particularly those involving new or frequently changing domains.
This intelligence briefing provides a comprehensive overview of the observed characteristics and behaviors associated with IP 54.38.147.123/32, enabling SOC analysts to make informed decisions regarding its monitoring and management within their security infrastructure.
