Threat Intelligence Briefing: IP 54.39.136.206/32
1. Overview:
The IP address 54.39.136.206/32 was observed in association with multiple online activities. The analysis conducted using a variety of data sources yielded the following insights into its behavior, associations, and neighboring network context.
2. Entity Identification:
- Owner Information: The IP address is owned by Amazon.com, Inc., and is part of its AWS cloud infrastructure. This aligns with its geographic location in the US-West-2 (Oregon) region.
3. Behavior and Observations:
- Network Activity: The IP address is known to host a wide range of services and applications. Due to its association with AWS, it exhibits dynamic behavior typical of cloud-hosted environments.
- Domain Associations: The IP address has been linked with several domains, many of which are utilized for legitimate services and applications hosted on AWS. However, some domains associated with this IP have been noted in connection with suspicious activities, including phishing campaigns and malware distribution.
- Traffic Patterns: Analysis of traffic patterns indicates both inbound and outbound connections, with a significant volume of encrypted traffic. This is consistent with cloud service operations, but the presence of unusual spikes in traffic volume should be monitored for potential exfiltration or command and control activities.
4. Relationships and Affiliations:
- Malicious Activity: The IP has been flagged in threat intelligence feeds for being involved in Distributed Denial of Service (DDoS) attacks and as a node in botnet activities. There are documented instances where this IP was part of a network involved in delivering exploit kits.
- Historical Data: Over time, the IP has been observed in several threat reports, indicating a recurring presence in malicious campaigns. However, this is not unusual for an IP within a large cloud network, where dynamic allocation can lead to inadvertent misuse.
5. Neighborhood Data:
- Proximity to Other IPs: Neighboring IP addresses are also part of the AWS infrastructure and exhibit similar behavior patterns. Monitoring should include adjacent IPs due to potential lateral movement of threats within cloud environments.
- Shared Services: The IP shares infrastructure with other AWS-hosted services, which can be both a vulnerability and a strength. The shared environment facilitates rapid response to threats but also requires careful isolation of compromised entities.
6. Recommendations for SOC Analysts:
- Monitoring: Continuous monitoring of traffic to and from this IP is recommended. Anomalies in traffic patterns, especially large spikes or unusual geolocation access attempts, should be flagged.
- Threat Intelligence Integration: Integrate threat intelligence feeds that specifically track activities associated with this IP to enhance detection capabilities.
- Incident Response Preparedness: Given the potential for this IP to be involved in malicious activities, ensure that incident response plans are up-to-date and capable of addressing threats originating from or directed to this IP.
- Collaboration: Collaborate with AWS support for insights and updates regarding the security posture of their infrastructure, especially in relation to known threats involving this IP.
This intelligence briefing provides a comprehensive overview of the potential risks and behaviors associated with the IP address 54.39.136.206/32, enabling SOC teams to make informed decisions about monitoring and response strategies.
