Date of Analysis: [Insert Date]
Summary:
The IP address 39.185.89.241/32 was analyzed using a comprehensive set of network intelligence tools to gather data on its profile, historical activity, relationships, and neighborhood characteristics. The following intelligence narrative summarizes the findings, providing actionable insights for Security Operations Center (SOC) analysts.
Profile Details:
- Geolocation: The IP address is located in China. The associated ASN (Autonomous System Number) indicates it is part of a network operated by China Mobile International Limited.
- Organization: The IP is registered to China Mobile International Limited, a major telecommunications company in China. The company provides a range of services, including mobile telephony and internet access.
Observation History:
- Activity Patterns: Historical data indicates consistent activity from this IP address, with traffic primarily directed towards a range of international destinations. There have been no significant anomalies or deviations from typical traffic patterns observed.
- Threat Intelligence Reports: The IP address has been flagged in several threat intelligence feeds for its involvement in spam distribution campaigns and potential command-and-control (C2) activities. However, there is no direct evidence of malicious intent or association with known threat actors.
Relationships:
- Associated Domains: The IP has been observed resolving to multiple domains, some of which have been previously associated with phishing and malware distribution activities. These domains have been dynamically registered and often exhibit short lifespans.
- Network Interactions: The IP has shown interactions with other IPs within the same ASN, suggesting possible coordination or shared infrastructure for legitimate telecommunications services.
Neighborhood Data:
- Proximity Analysis: Neighboring IP addresses within the same subnet have been associated with similar telecommunications services. There is no evidence of widespread malicious activity within this immediate IP neighborhood.
- Network Behavior: The surrounding network exhibits typical behavior for a telecommunications provider, with no significant deviations that would suggest a broader network compromise.
Conclusions and Recommendations:
- Risk Level: Moderate. While the IP address has been flagged for suspicious activities, the primary function appears to be legitimate telecommunications services. The presence of associated domains with malicious histories warrants caution.
- Actionable Steps: SOC teams should implement monitoring for any connections to known malicious domains associated with this IP. Implementing egress filtering and DNS blacklisting for these domains can help mitigate potential threats.
- Continuous Monitoring: Given the dynamic nature of the associated domains, continuous monitoring and updating of threat intelligence feeds are recommended to promptly identify and respond to any emerging threats.
This intelligence briefing provides a comprehensive overview of the IP address 39.185.89.241/32, aiding SOC analysts in making informed decisions regarding network security and threat mitigation strategies.
