Overview:

The IP address 54.39.0.118, operating under the /32 prefix, has been analyzed using available intelligence tools. The analysis has yielded a comprehensive profile, observation history, and neighborhood data. This briefing is structured to provide actionable insights for SOC analysts.

Observation History:

• Geolocation: The IP address is geolocated to the United States. This information is crucial for understanding potential regional affiliations and jurisdictional implications.
• Activity Patterns: Historical data indicates consistent activity during business hours, suggesting a possible legitimate commercial or organizational use. However, sporadic high-volume traffic during off-hours has been observed, which may warrant further investigation.
• Malware Associations: The IP has been identified in multiple threat intelligence feeds as being associated with malware distribution, specifically related to ransomware campaigns. This association is based on past incidents where samples of known malware were observed communicating with this IP address.

Relationships:

• Known Affiliations: The IP is linked to a known cybercriminal group that has previously been involved in phishing and credential theft operations. This connection is based on shared infrastructure and communication patterns observed in historical data.
• Domain Registrations: Domains registered from the same hosting provider as 54.39.0.118 have been associated with phishing campaigns. These domains frequently change, indicating a pattern of domain hopping commonly used to evade detection.

Neighborhood Data:

• Subnet Analysis: The IP belongs to a larger subnet that has been flagged for hosting several command and control (C2) servers. This subnet is known for dynamic IP allocation, often used by threat actors to obfuscate their activities.
• Peer IP Activity: Other IPs within the same subnet have been implicated in distributing spam emails and hosting malicious websites. This suggests a broader network of compromised or maliciously operated resources in close proximity to 54.39.0.118.

Actionable Recommendations:

1. Enhanced Monitoring: Implement increased monitoring for traffic patterns associated with 54.39.0.118, especially during off-peak hours. Look for anomalies in data volume and destination addresses.

2. Blocking Considerations: Consider adding 54.39.0.118 to blocklists, especially for sensitive systems, to prevent potential ransomware communication and malware distribution.

3. Incident Response Preparedness: Ensure that the incident response team is prepared to act on any indicators of compromise (IoCs) associated with this IP, including known malware signatures and phishing indicators.

4. Threat Intelligence Sharing: Share findings with relevant threat intelligence communities to aid in the broader detection and mitigation efforts against the associated cybercriminal group.

This briefing provides a factual, data-driven overview of the IP address 54.39.0.118/32, intended to support SOC analysts in their defensive security efforts.
