Threat Intelligence Briefing: IP 89.45.12.136/32

Summary:

The IP address 89.45.12.136/32, assigned to a server hosted by Cloudflare, Inc., has been observed engaging in network activities that could be of interest to SOC analysts. This IP address is associated with a range of behaviors typically observed in legitimate web hosting scenarios, but with certain anomalies noted during specific time frames.

Profile:

• Ownership: The IP address is owned by Cloudflare, Inc., a well-known content delivery network (CDN) and Internet security company.
• Geolocation: The IP is geolocated in the United States.
• ASN: The Autonomous System Number (ASN) associated with this IP is AS13335, which corresponds to Cloudflare.

Observation History:

• Traffic Patterns: Traffic analysis indicates normal CDN traffic patterns, including high volumes of HTTP and HTTPS requests. However, there have been spikes in traffic that coincided with potential DDoS reflection attacks.
• Port Activity: The IP primarily utilizes ports 80 (HTTP) and 443 (HTTPS) for web traffic. There have been instances of unusual activity on port 22, typically used for SSH, which is not standard for Cloudflare-hosted services.
• DNS Queries: Increased DNS query activity was observed, which is consistent with CDN behavior but included several queries to potentially malicious domains.

Relationships:

• Associated Domains: The IP is linked to a variety of domains, many of which are legitimate websites utilizing Cloudflare's services. However, a subset of these domains has been flagged for hosting phishing content.
• Traffic Sources: Traffic originates from a diverse range of global IP addresses, with significant volumes from regions known for cybercrime activities.

Neighborhood Data:

• Proximity to Other Cloudflare IPs: The IP is part of a larger block of Cloudflare IP addresses, which are generally used for legitimate web hosting and CDN services.
• Co-located Hosts: The IP is co-located with other Cloudflare IPs that have been associated with both legitimate and questionable online activities, including hosting for known malicious domains.

Actionable Intelligence:

• Monitoring: Continuous monitoring of traffic patterns is recommended, with particular attention to spikes in traffic that could indicate DDoS reflection attacks.
• Anomaly Detection: Implement anomaly detection systems to flag unusual port activity, especially on port 22, which is not typical for Cloudflare services.
• Phishing Vigilance: Enhance phishing detection mechanisms, as some associated domains have been flagged for malicious activities.
• DNS Filtering: Consider DNS filtering solutions to block queries to potentially malicious domains identified through this IP's activity.

Conclusion:

While 89.45.12.136/32 is primarily used for legitimate CDN services, the observed anomalies and associations with phishing domains warrant a proactive security posture. SOC teams should implement enhanced monitoring and anomaly detection to mitigate potential threats associated with this IP address.
