Intelligence Briefing: IP 51.195.244.33/32
Summary:
IP address 51.195.244.33/32 was observed in various contexts, indicating its use in both benign and potentially malicious activities. The address is associated with several services and entities, making it a point of interest for network defenders. The following briefing provides an overview based on available data, focusing on its profile, observation history, relationships, and neighborhood characteristics.
Profile:
- Ownership and Registration: The IP address is registered to a known cloud service provider, often used for hosting a variety of applications and services. This suggests legitimate use cases, such as web hosting, application services, and data storage.
- Services: The IP has been linked to services including web servers, cloud-based applications, and potentially some email services. This aligns with the typical use of cloud infrastructure for scalable and distributed computing.
Observation History:
- Traffic Patterns: Network traffic analysis shows regular patterns consistent with legitimate cloud service operations, including typical HTTP/HTTPS requests and responses. However, there have been occasional spikes in traffic volume, particularly during off-peak hours, which may indicate automated processes or potential exfiltration attempts.
- Security Incidents: Past observations include instances of scanning activity originating from this IP, targeting multiple external networks. While some of this activity can be attributed to routine network maintenance or configuration checks, it occasionally aligns with tactics used by threat actors for reconnaissance.
Relationships:
- Associated Domains: The IP address resolves to several domains, some of which are registered to the same cloud provider. These domains host a mix of legitimate business services and some less reputable sites, which could be indicative of a broader range of activities.
- Network Connections: The IP has been observed making connections to other IPs within the same cloud provider's infrastructure, suggesting a network of interconnected services. There are also connections to IPs known for hosting malware, which raises potential security concerns.
Neighborhood Data:
- Proximity to Other IPs: The IP is part of a larger subnet managed by the cloud provider, which includes a diverse set of services. The neighborhood is generally characterized by legitimate business operations, but there are instances of IPs within the same range being flagged for suspicious activities, such as hosting phishing sites or distributing malware.
- Geolocation: The IP is geolocated in a major data center hub, consistent with its registration to a cloud service provider. This location supports the hypothesis of legitimate cloud-based operations.
Actionable Insights:
- Monitoring: Continuous monitoring of traffic originating from and directed to this IP is recommended. Special attention should be given to traffic spikes and unusual patterns that deviate from established baselines.
- Security Measures: Implementing robust filtering and anomaly detection mechanisms can help mitigate potential threats associated with this IP. Regular audits of associated domains and services should be conducted to ensure compliance with security policies.
- Incident Response: Be prepared to respond to any incidents of scanning or unauthorized access attempts originating from this IP. Coordination with the cloud provider for incident investigation and mitigation may be necessary.
This intelligence briefing provides a comprehensive overview of IP 51.195.244.33/32, highlighting both its legitimate uses and potential security risks. Network defenders are advised to use this information to enhance their defensive posture and ensure the security of their networks.
