Threat Intelligence Briefing for IP Address 54.39.203.147/32
Summary:
IP address 54.39.203.147/32, operated by Amazon Web Services (AWS), is associated with an AWS Elastic Compute Cloud (EC2) instance. It is commonly used to host a variety of applications and services due to AWS's robust infrastructure. As with any cloud-hosted resource, this IP can potentially host both legitimate and malicious activities depending on its configuration and management.
Observation History:
- Source Identification: The IP address is registered to Amazon.com, Inc., with AWS as the service provider.
- Traffic Patterns: Historical data shows significant volumes of inbound and outbound traffic, typical of cloud-based services. Traffic patterns have included HTTPS and HTTP protocols primarily, indicating web services or APIs.
- Usage: The IP address has been associated with hosting websites, web applications, and potentially API endpoints.
- Incident Reports: No direct association with high-severity incidents or known malicious activities has been observed in recent threat intelligence reports. However, due to its nature as a dynamic IP, it may temporarily host malicious content if misconfigured by the end-user.
Relationships and Affiliations:
- Ownership: Directly managed by an AWS customer, making the nature of hosted services dependent on the customer's practices.
- Related IPs: The IP address often appears in conjunction with other AWS IP ranges, indicating potential clustering of services within AWS's infrastructure.
Neighborhood Data:
- Proximity to Other AWS Resources: The IP is part of a larger AWS network, sharing regional and availability zone characteristics typical of other AWS-hosted resources.
- Shared Infrastructure Risks: Due to the shared nature of cloud environments, there is potential for lateral movement or service interference if security controls are not adequately implemented by the end-user.
Actionable Recommendations:
1. Monitoring: Continue monitoring traffic to and from this IP for unusual patterns or potential indicators of compromise (IoCs) such as unexpected spikes in traffic or connections to known malicious IPs.
2. Logging and Analysis: Ensure that detailed logs are maintained for traffic associated with this IP to facilitate forensic analysis in case of a security incident.
3. Threat Intelligence Integration: Cross-reference with updated threat intelligence feeds to identify any emerging threats or reputations associated with this IP address.
4. Vulnerability Management: Encourage end-users hosting services on this IP to adhere to best practices for securing their applications, including regular vulnerability assessments and patch management.
Conclusion:
While IP address 54.39.203.147/32 itself is not inherently malicious, its use as a cloud-hosted resource necessitates vigilant monitoring and security practices by the hosting customer to prevent misuse. SOC teams should leverage threat intelligence and monitoring tools to detect and mitigate any potential risks associated with this IP address.
