Threat Intelligence Briefing: IP 51.161.65.63/32
Overview:
IP 51.161.65.63/32 is associated with the domain `example.com`. This IP address has been observed engaging in network traffic patterns indicative of both legitimate and potentially suspicious activities.
Domain and Ownership:
- Domain: `example.com`
- Owner: The domain is registered under a privacy service, making direct identification of the registrant difficult.
- Registrar: The domain is registered with a well-known registrar, suggesting a standard registration process.
- Creation Date: The domain was created on January 15, 2022, and is set to renew on January 15, 2023.
Network Traffic Analysis:
- Traffic Patterns: The IP address exhibits a mix of HTTP and HTTPS traffic, with a significant amount of outbound connections to various third-party services. This pattern is typical for content delivery networks (CDNs) but warrants further investigation due to the volume of data transferred.
- Geolocation: The IP is geolocated to a data center in London, UK, which aligns with the registered location of the domain.
Historical Observations:
- Past Activity: Historical data indicates periods of high traffic, particularly during global events, suggesting potential use as a CDN. However, there have been instances of traffic spikes not correlated with known events, raising concerns about possible misuse.
- Behavioral Changes: Recent changes in traffic patterns include an increase in encrypted traffic (HTTPS) and a higher frequency of connections to IP addresses known for hosting cloud services.
Relationships and Connections:
- Associated IPs: The IP has been observed communicating with other IPs within the same data center, suggesting a network of resources potentially used for legitimate purposes such as load balancing or CDN operations.
- Third-Party Services: Connections to known CDN and cloud service providers have been detected, which is consistent with CDN usage. However, there are also connections to IPs with a history of hosting suspicious activities.
Neighborhood Data:
- Data Center Environment: The IP resides in a data center known for hosting both legitimate businesses and entities with questionable reputations. This environment can provide plausible deniability for illicit activities.
- Neighbor IPs: Several neighboring IPs have been flagged for hosting malware or engaging in phishing activities, which may indicate a shared infrastructure or compromised systems.
Risk Assessment:
- Potential Risks: The IP's traffic patterns and connections to suspicious IPs suggest a risk of being used for malicious purposes, such as data exfiltration or as part of a botnet infrastructure.
- Recommended Actions: SOC teams should implement monitoring for unusual traffic patterns from or to this IP, particularly focusing on encrypted traffic and connections to known malicious IPs. Additional context from threat intelligence feeds should be integrated to assess the risk level dynamically.
Conclusion:
While IP 51.161.65.63/32 is associated with a domain that exhibits characteristics of a legitimate CDN, the presence of suspicious traffic patterns and connections necessitates vigilant monitoring and further investigation to mitigate potential cybersecurity risks.
