Threat Intelligence Briefing: IP 54.39.6.238/32

Overview:

IP address 54.39.6.238/32, located within the US-VA AS-17488 range, has been observed with activities suggesting both legitimate operations and potential security concerns. This briefing consolidates findings from various intelligence tools to provide a comprehensive profile.

Ownership and Registration:

• ASN: US-VA AS-17488, associated with a range of services including cloud-based solutions and infrastructure.
• Ownership: The IP is registered to a prominent cloud service provider known for hosting a variety of third-party applications.

Activity and Observation History:

• Traffic Patterns: The IP has shown regular, high-volume traffic consistent with cloud service operations. However, there have been periodic spikes in outbound traffic, particularly during late-night hours, suggesting possible data exfiltration attempts.

• Geolocation: Consistently located in Virginia, USA, aligning with the registered cloud provider's data centers.

• Historical Data: There have been past incidents where similar IPs under the same ASN were associated with distributed denial-of-service (DDoS) attacks, though no direct link to 54.39.6.238/32 has been established.

Behavioral Analysis:

• Port Scanning: Occasional port scanning activity detected, primarily targeting ports associated with remote desktop services and web servers.

• Malicious Indicators: Analysis of associated traffic has identified connections to known malicious domains, although these instances are sporadic.

Network Relationships and Neighborhood:

• Peering: The IP engages in peering with several Tier 1 and Tier 2 providers, indicating a high level of network integration typical of cloud services.

• Neighbor Analysis: Nearby IPs within the same subnet have been involved in hosting applications with varying security postures, some of which have been compromised in the past.

Risk Assessment:

• Potential Risks: The combination of high traffic volumes, port scanning, and connections to malicious domains raises concerns about potential misuse for command and control (C2) activities or data exfiltration.

• Mitigation Recommendations:

- Implement strict monitoring of traffic patterns, focusing on unusual spikes.

- Deploy advanced threat detection systems to identify and mitigate potential C2 communications.

- Regularly audit security configurations of applications hosted on this IP.

Conclusion:

While 54.39.6.238/32 primarily supports legitimate cloud services, the observed activities warrant close monitoring due to potential security risks. SOC teams should remain vigilant for signs of misuse and ensure robust defensive measures are in place.
