Threat Intelligence Briefing: IP 209.173.10.75/32

Overview:

The IP address 209.173.10.75/32 was observed across multiple data sources and tools, revealing its association with certain online activities and hosting characteristics. The analysis aimed to determine its profile, historical activities, and potential security implications.

Ownership and Hosting Details:

• The IP address 209.173.10.75/32 was associated with Amazon Web Services (AWS). Specifically, it was linked to an AWS EC2 instance, indicating that the server was likely provisioned under a cloud hosting environment.
• The server was hosted under a customer account managed by AWS, which suggests that the entity controlling this IP could have access to AWS's extensive cloud computing resources.

Domain and Subdomain Associations:

• Historical DNS records and WHOIS data identified multiple domains and subdomains linked to this IP address. These domains were primarily involved in web hosting and content delivery services.
• The domains associated with this IP showed a pattern of short-lived registrations, a common characteristic of domains used for temporary services, potentially indicating a transient nature of hosted content.

Network Activity and Behavior:

• Traffic analysis indicated that the IP engaged in both inbound and outbound communications, with a notable volume of data transfer during specific time windows, suggesting scheduled or automated operations.
• The IP was involved in connections with other cloud-based IPs, consistent with cloud services' typical interaction patterns, but also had connections to known malicious IPs in past observations, raising potential security concerns.

Historical Observations:

• Past data logs revealed intermittent spikes in traffic volume, often correlating with periods of increased activity on the associated domains. These spikes were occasionally linked to distributed denial-of-service (DDoS) mitigation attempts.
• The IP address had been flagged in past security reports for hosting phishing campaigns, with associated domains used to distribute malicious links or content.

Relationships and Neighborhood Data:

• The IP address was part of a cluster of IPs also hosted on AWS, many of which had similar hosting and activity profiles, including associations with temporary domains and dynamic content delivery.
• Neighboring IPs showed similar patterns of activity, with some being identified in past threat intelligence feeds as sources of spam or malware distribution.

Security Implications:

• Given the transient nature of the domains and the historical involvement in phishing and DDoS activities, there is a potential risk that this IP could be leveraged for malicious purposes in the future.
• Continuous monitoring of traffic patterns and domain associations is recommended to detect any shifts towards more overtly malicious behavior.

Actionable Recommendations:

• Implement network monitoring to detect unusual traffic patterns or connections to known malicious IPs originating from or targeting this IP address.
• Block or filter traffic from domains historically associated with this IP if they exhibit suspicious behavior or are flagged by threat intelligence feeds.
• Regularly update threat intelligence feeds to capture any new associations or activities linked to this IP address.

This intelligence briefing provides a comprehensive view of the activities and potential risks associated with IP 209.173.10.75/32, aiding SOC teams in proactive defense measures.
