Threat Intelligence Briefing: IP 13.62.230.208/32

Summary:

IP address 13.62.230.208/32 was observed engaging in a series of network activities that could be indicative of potential cybersecurity concerns. Analysis was conducted using a comprehensive suite of network intelligence tools to determine its profile, activity history, relationship with other IP addresses, and its surrounding network environment.

Profile Information:

• Geolocation: The IP address 13.62.230.208/32 is geolocated in the United States. This location was consistently verified across multiple geolocation databases.
• ASN: The IP is associated with Amazon AWS, as indicated by its allocation within a known range of Amazon's Autonomous System Numbers (ASNs).

Observation History:

• Activity Patterns: Historical data showed a high volume of outbound traffic primarily targeting various domains associated with cloud services and data centers, typical of legitimate cloud-hosted operations. However, periodic spikes in traffic volume were noted, which were concentrated towards specific destination IPs not commonly associated with standard AWS operations.
• Port Usage: Predominant use of port 443 (HTTPS) was observed, which is consistent with encrypted data transfer. Intermittent connections via port 22 (SSH) were also detected, suggesting potential server management or data exfiltration activities.

Relationships:

• Associated Domains: DNS records indicated that this IP was used to access multiple subdomains related to a larger corporate domain, which has legitimate business operations. However, some of the accessed subdomains were not widely recognized in public DNS records, suggesting potential internal or private usage.
• Traffic Correlation: Traffic analysis showed correlation with several other IP addresses within the same AWS range, indicating possible network segmentation or shared infrastructure use. This was typical for AWS-hosted environments but required further scrutiny due to the volume and nature of the traffic patterns observed.

Neighborhood Data:

• Network Environment: The IP resides within a densely populated cloud infrastructure environment, with neighboring IP addresses also managed by AWS. This environment is characteristic of high-volume data operations, typical for cloud service providers.
• Threat Landscape: No direct associations with known malicious IP addresses were found in threat intelligence databases. However, the sporadic traffic spikes towards certain external IPs warranted further investigation to rule out potential command-and-control (C2) communication or data exfiltration.

Conclusion:

While IP 13.62.230.208/32 is primarily associated with legitimate AWS operations, its activity patterns and traffic spikes towards non-standard destination IPs necessitate further investigation. SOC teams should monitor for unusual activity, especially focusing on the times of traffic surges and the destinations involved. Implementing additional logging and anomaly detection for SSH and non-standard HTTPS connections could provide further insights into the nature of these activities.

Actionable Recommendations:

1. Continuous Monitoring: Implement enhanced monitoring on traffic patterns, especially during identified spike periods.

2. Traffic Analysis: Conduct a deeper analysis of traffic to the anomalous external IPs to determine the nature of the communications.

3. Network Segmentation: Consider isolating traffic from this IP within internal networks to mitigate potential risks.

4. Incident Response Planning: Prepare an incident response strategy in case further investigation uncovers malicious activity.

This briefing provides a comprehensive overview of the observed activities and potential risks associated with IP 13.62.230.208/32, enabling SOC analysts to take informed actions based on the gathered intelligence.
