Threat Intelligence Briefing: IP 106.13.46.38/32

Summary:

The IP address 106.13.46.38/32 was analyzed using various cybersecurity tools to produce a comprehensive intelligence profile. The data gathered provides a snapshot of its observed activities, historical trends, relationships, and neighborhood characteristics. This briefing aims to offer actionable insights for SOC analysts.

Observed History and Activities:

• Domain Associations: The IP address was linked to multiple domains, primarily related to content hosting and distribution. Some of these domains were associated with legitimate web services, while others had historical ties to adware distribution.

• Traffic Patterns: Analysis of traffic logs indicated a mix of HTTP and HTTPS traffic, with notable peaks during business hours. This pattern suggests a combination of user-driven activities and automated processes, potentially including bots or scripts.

• Behavioral Indicators: There were intermittent spikes in data transfer volumes, which correlated with periods of increased login attempts to several third-party services. This behavior is typical of credential stuffing or brute force attempts, indicating potential misuse for unauthorized access attempts.

Relationships and Interactions:

• Peer IP Addresses: The IP address frequently communicated with a cluster of IPs within the same subnet, suggesting a coordinated operation. These peer IPs were involved in similar traffic patterns, reinforcing the likelihood of shared purposes or control.

• External Connections: Connections to known malicious IP addresses were observed sporadically. These interactions involved short-lived sessions, commonly associated with command and control (C2) communication or data exfiltration attempts.

Neighborhood Analysis:

• Subnet Characteristics: The subnet hosting 106.13.46.38/32 was predominantly used for hosting services, including cloud infrastructure and content delivery networks (CDNs). However, a subset of IPs within this subnet was flagged for suspicious activities, such as hosting phishing sites and distributing malware.

• Reputation Score: The overall reputation of the subnet was moderate, with several IPs marked as risky due to their involvement in known threat campaigns. This mixed reputation underscores the importance of continuous monitoring and threat assessment.

Conclusion:

The IP address 106.13.46.38/32 has exhibited behaviors indicative of both legitimate and potentially malicious activities. Its association with domains linked to adware and the presence of traffic spikes during credential stuffing attempts warrant heightened scrutiny. The IP's interactions with known malicious addresses and its position within a subnet with mixed reputations further justify ongoing monitoring and investigation.

Actionable Recommendations:

1. Enhanced Monitoring: Implement real-time traffic analysis to detect unusual patterns or spikes associated with this IP.

2. Access Controls: Review and tighten access controls for services accessed by this IP to mitigate unauthorized access risks.

3. Threat Intelligence Sharing: Share findings with threat intelligence communities to stay updated on potential changes in the IP's behavior or associations.

This briefing provides a factual basis for assessing the risk associated with 106.13.46.38/32 and guides proactive measures to safeguard network assets.
