Threat Intelligence Briefing: IP Address 83.239.84.130/32

Summary:

The IP address 83.239.84.130, allocated by ARIN, is associated with the Russian Federation, specifically operated by PJSC Rostelecom. This IP address was observed engaging in various network activities, which have been categorized based on available data from network intelligence tools.

Observation History:

1. Traffic Patterns:

- The IP address demonstrated consistent outbound traffic, predominantly directed towards several well-known cloud service providers. This activity pattern is indicative of legitimate business operations, typical of telecommunications companies engaging in data management and customer support functions.

2. Port Scans:

- On multiple occasions, the IP was involved in port scanning activities. These activities predominantly targeted ports commonly associated with web services (e.g., port 80, port 443), suggesting an attempt to map services across accessible networks.

3. Domain Name Resolution:

- DNS queries originating from this IP address frequently resolved to domains associated with both legitimate services and known malicious entities. This behavior is not uncommon for infrastructure used by large organizations, where network segmentation and security policies can vary.

Relationships:

1. Associated Hosts:

- The IP address was part of a network cluster primarily consisting of other Rostelecom-operated addresses. These addresses have demonstrated similar traffic patterns and are geographically proximate, suggesting a controlled, centralized management.

2. Communication with External IPs:

- The IP engaged in communication with a set of external IP ranges known to host content delivery networks (CDNs) and data centers, which aligns with the operational profile of a telecommunications provider.

Neighborhood Data:

1. Subnet Analysis:

- Within the subnet, several IPs were observed conducting similar outbound traffic, primarily targeting cloud services and CDNs. This subnet behavior supports the hypothesis of legitimate enterprise activity.

2. Anomalous Activity:

- There were sporadic instances of anomalous traffic patterns, including brief spikes in volume and unusual time-of-day activity. These anomalies were not indicative of sustained malicious behavior but warrant monitoring for potential misuse.

Conclusion:

The IP address 83.239.84.130 is primarily associated with legitimate business operations conducted by PJSC Rostelecom. While the traffic patterns and port scanning activities align with typical enterprise behavior, the occasional DNS resolution to known malicious domains and observed anomalies suggest a need for continued monitoring. SOC teams are advised to:

• Implement network segmentation and access controls to mitigate potential risks.
• Monitor for unusual traffic spikes or deviations from established patterns.
• Review firewall and intrusion detection system logs for any signs of unauthorized access or data exfiltration attempts.

This analysis provides a comprehensive overview of the observed activities related to IP 83.239.84.130, offering actionable insights for network defenders.
