Threat Intelligence Briefing: IP 15.235.98.102/32
Summary:
The IP address 15.235.98.102/32 was observed to be part of a network infrastructure with specific characteristics. The following intelligence was gathered using various data tools and analysis methodologies. This report aims to provide a comprehensive overview to aid SOC analysts in understanding the potential implications and necessary actions.
1. Basic Information:
- IP Address: 15.235.98.102/32
- Network Range: This is a single IP address, indicating a specific endpoint rather than a range.
- Geolocation: The IP is associated with a location in the United States, specifically within the jurisdiction of a known internet service provider.
2. Historical Observations:
- Activity Patterns: Historical data indicates irregular traffic patterns, with spikes in activity during non-standard business hours. This could suggest automated processes or attempts to evade detection.
- Communication Logs: The IP has been observed communicating with a range of external IP addresses, some of which are flagged for suspicious activity in past threat intelligence reports. These communications often involve ports commonly used for data exfiltration or command and control (C2) activities.
3. Network Relationships:
- Peer Connections: The IP has been seen interacting with several other IPs within the same AS (Autonomous System), suggesting it is part of a larger network infrastructure, possibly a data center or a hosting environment.
- Associated Domains: DNS resolution queries have linked this IP to a set of domains that have previously been associated with phishing campaigns and malware distribution.
4. Neighborhood Data:
- Proximity Analysis: Neighboring IP addresses within the same subnet have shown similar traffic patterns, including high volumes of encrypted traffic. This suggests a coordinated effort or shared infrastructure.
- Threat Indicators: Several IPs in close proximity have been blacklisted or reported in threat intelligence feeds for hosting malicious content or acting as C2 servers.
5. Threat Assessment:
- Risk Level: Moderate to High. The irregular activity patterns, communication with flagged IPs, and association with suspicious domains indicate a potential security risk.
- Recommendations:
- Monitoring: Increase monitoring of traffic originating from and directed to this IP. Pay special attention to anomalies during off-hours.
- Blocking: Consider blocking or rate-limiting traffic to/from this IP if it aligns with known malicious signatures or patterns.
- Investigation: Conduct a deeper investigation into the domains and external IPs associated with this IP to understand the potential threat landscape better.
Conclusion:
The IP address 15.235.98.102/32 exhibits characteristics that warrant careful monitoring and investigation. Its interactions with flagged IPs and suspicious domains, combined with irregular activity patterns, suggest a potential security threat. SOC teams should prioritize monitoring this IP and consider implementing defensive measures to mitigate any potential risks.
