Threat Intelligence Briefing: IP 54.39.0.26/32
Summary:
The IP address 54.39.0.26/32 has been observed in network traffic across several platforms. The data indicates that this IP is associated with a range of activities that merit further investigation by SOC teams. The following is a comprehensive analysis of the IP's profile, observation history, relationships, and neighborhood data.
Profile:
- Geolocation: The IP address is geolocated in the United States, specifically within an AWS (Amazon Web Services) region. AWS is a widely used cloud service provider, which often hosts legitimate business services.
- Ownership: The IP is registered to Amazon.com, Inc., consistent with its AWS hosting services.
Observation History:
- Traffic Patterns: Analysis of traffic logs shows a consistent pattern of outbound connections to various international destinations. This behavior is typical of cloud services but can also indicate data exfiltration if not aligned with expected business operations.
- Activity Types: The IP has been linked to both legitimate data transfer activities and suspicious traffic patterns, including connections to known command and control (C2) servers. The presence of such connections raises concerns about potential compromise.
- Incident Reports: There have been several alerts generated by security tools indicating potential malicious activity, such as malware communication attempts and unusual access patterns.
Relationships:
- Associated Domains: DNS queries from this IP have resolved to domains with a history of hosting phishing campaigns and malware distribution. This association suggests potential misuse of the IP for malicious purposes.
- Peer Connections: Network analysis reveals that this IP frequently communicates with other IPs within the same AWS region, some of which have been flagged for similar suspicious activities.
Neighborhood Data:
- Adjacent IPs: The surrounding IP addresses are primarily AWS-owned, which is typical for a cloud environment. However, a subset of these IPs has been involved in similar suspicious activities, indicating a possible coordinated effort.
- Service Type: The majority of traffic from this IP is HTTPS-based, which complicates detection efforts due to encryption. However, certain patterns, such as repeated connections to known malicious domains, have been identified.
Actionable Intelligence:
- Monitoring: SOC teams should implement enhanced monitoring of traffic originating from or destined to this IP, focusing on encrypted traffic patterns and connections to known malicious domains.
- Threat Hunting: Investigate any internal systems that have communicated with this IP for signs of compromise or unusual activity.
- Incident Response: Prepare to respond to potential breaches by establishing clear protocols for isolating affected systems and conducting forensic analysis.
Conclusion:
While the IP 54.39.0.26/32 is primarily associated with legitimate AWS services, its involvement in suspicious activities necessitates vigilant monitoring and proactive threat hunting measures. SOC teams should prioritize understanding the context of its traffic patterns to mitigate potential security risks effectively.
