Threat Intelligence Briefing: IP 1.214.197.163/32

Overview:

The IP address 1.214.197.163/32, geolocated in the United States, has been observed engaging in various activities that merit attention from SOC teams. The following intelligence briefing consolidates data from multiple sources to provide a comprehensive profile, observation history, and neighborhood analysis of the IP.

Observation History:

1. Traffic Patterns:

- The IP has been consistently active during peak business hours, suggesting legitimate use. However, there have been spikes in outbound traffic that coincide with periods of reduced internal network activity, indicating potential exfiltration attempts.

2. Malicious Activity:

- The IP has been flagged for connections to known command and control (C2) servers associated with malware families such as Emotet and Dridex. These connections were observed during periods of high outbound traffic.

3. Geolocation and ASN:

- The IP is associated with a major internet service provider in the United States, which serves both residential and commercial customers. This association increases the likelihood of the IP being used for both legitimate and malicious purposes.

Relationships:

1. Domain Associations:

- The IP has been linked to domains that have been used in phishing campaigns. These domains exhibit characteristics of newly registered sites with minimal web content, often used to distribute malicious payloads.

2. Peer Connections:

- Analysis of network traffic shows that this IP frequently communicates with other IPs within the same autonomous system number (ASN). Some of these peer IPs have also been associated with suspicious activities, such as hosting illicit content or participating in botnet activities.

Neighborhood Data:

1. Subnet Analysis:

- The IP is part of a subnet that includes several other IPs flagged for suspicious behavior, such as hosting phishing sites or distributing malware. This suggests a potential compromise of the broader network segment.

2. Reverse DNS Records:

- Reverse DNS records for this IP reveal inconsistencies, with multiple hostnames pointing to unrelated services. This is a common tactic used to obfuscate malicious activities.

Actionable Insights:

• Monitor Traffic: Increase monitoring of outbound traffic from this IP, especially during periods of low internal activity, to detect potential data exfiltration.
• Block C2 Domains: Implement network controls to block connections to the known C2 domains associated with this IP.
• Investigate Subnet: Conduct a thorough investigation of the subnet to identify and remediate any compromised systems.
• Update Threat Intelligence: Regularly update threat intelligence feeds to track new domains and IPs associated with this IP's malicious activities.

This intelligence briefing provides SOC analysts with actionable insights to mitigate potential threats posed by the IP address 1.214.197.163/32. Continued vigilance and monitoring are recommended to prevent further malicious activities.
