Profile:
- Geolocation: The IP address is geolocated in Russia, specifically within Moscow. This location has been consistent across multiple observations.
- Ownership: The IP is registered to a known telecommunications provider operating in the region. Historical data indicates stability in registration details, with no recent changes to the registrant or contact information.
Observation History:
- Activity Patterns: The IP address has been active primarily during business hours, aligning with typical usage patterns for legitimate services. However, there have been sporadic spikes in activity during non-standard hours, suggesting potential misuse or automated processes.
- Traffic Analysis: Network traffic analysis revealed a mix of legitimate and suspicious activities. The IP engaged in regular data exchanges with several known business entities, but also participated in irregular data transfers with several unregistered or low-reputation domains.
Relationships:
- Associated Domains: The IP has communicated with domains known for hosting command and control (C2) servers, although direct malicious intent cannot be conclusively established. These domains have histories of involvement in phishing and malware distribution.
- Peer IPs: Analysis of neighboring IPs revealed connections to a network of IPs with mixed reputations. Some peers have been flagged for involvement in distributed denial-of-service (DDoS) attacks and other malicious activities.
Neighborhood Data:
- Network Segmentation: The IP is part of a larger network segment associated with the telecommunications provider. While the majority of traffic within this segment appears legitimate, a subset of IPs has been implicated in malicious campaigns.
- Behavioral Anomalies: Within its neighborhood, 51.222.95.15/32 showed occasional deviations from typical network behavior, including unusual packet sizes and patterns that could indicate exfiltration attempts or data obfuscation.
Actionable Insights:
- Monitoring Recommendations: Continuous monitoring of traffic patterns associated with 51.222.95.15/32 is advised, with particular attention to anomalies during non-business hours.
- Threat Mitigation: Implement network segmentation and access controls to isolate traffic from this IP, especially when interacting with known suspicious domains.
- Incident Response Preparedness: Prepare incident response protocols for potential threats identified through traffic analysis, including DDoS and data exfiltration scenarios.
Conclusion:
IP 51.222.95.15/32 presents a dual profile of legitimate business operations intertwined with potential security risks. SOC teams are advised to maintain vigilance, leveraging both automated detection systems and manual analysis to mitigate identified threats.
