Threat Intelligence Briefing: IP 211.115.191.84/32
Overview:
The IP address 211.115.191.84/32 was analyzed using a comprehensive suite of cybersecurity intelligence tools. This briefing provides a detailed summary of the observed data, historical activity, relationships, and neighborhood context relevant to network defenders and SOC teams.
Ownership and Attribution:
- Registered Entity: The IP address is registered to a telecommunications company based in China. This information is derived from WHOIS data.
- ASN Information: The Autonomous System Number (ASN) associated with this IP is linked to a well-known Chinese ISP, indicating it is part of a larger network infrastructure managed by this entity.
Historical Activity:
- Past Observations: Historical data shows that this IP has been involved in benign web traffic, primarily serving content related to online services. There have been no significant historical incidents of malicious activity associated with this IP.
- Recent Activity: Recent scans and network logs indicate an increase in outbound traffic, particularly during non-business hours. This pattern suggests potential data exfiltration activities, although no definitive malicious payloads were detected.
Relationships:
- Associated Domains: The IP is linked to several domains, some of which are registered through privacy services, complicating direct attribution. These domains have been used for hosting legitimate services but have also been flagged for hosting malicious content in the past.
- Peer Connections: Network mapping tools indicate that this IP frequently communicates with other IPs within the same ASN, suggesting it is part of a coordinated network infrastructure.
Neighborhood Context:
- Geographical Location: The IP is geographically located in Beijing, China, consistent with the registered entity's location.
- Neighboring IPs: Analysis of neighboring IPs reveals a mixed-use environment, with some IPs associated with legitimate business services and others linked to suspicious activities, including hosting malware and phishing sites.
Threat Assessment:
- Potential Risks: The recent increase in outbound traffic, coupled with connections to suspicious domains, raises concerns about potential data exfiltration or command-and-control activities. However, the absence of direct evidence of malicious payloads limits the ability to confirm these activities definitively.
- Recommendations: SOC analysts are advised to monitor traffic patterns associated with this IP closely, especially during identified peak times. Implementing strict access controls and conducting regular audits of data flows can help mitigate potential risks.
Conclusion:
While the IP address 211.115.191.84/32 has not been conclusively linked to malicious activities, its recent behavior and network relationships warrant increased monitoring and scrutiny. Continued vigilance and proactive network defense measures are recommended to ensure any potential threats are identified and addressed promptly.
