Threat Intelligence Briefing: IP 123.207.53.245/32
Overview:
The IP address 123.207.53.245/32 was observed and analyzed using a range of data collection tools and sources, including passive DNS records, WHOIS data, open-source intelligence (OSINT) scans, and network traffic analysis. The findings are summarized below, highlighting the potential security implications and relevant observations.
Identification and Registration:
- ISP and Location: The IP is allocated to an ISP in the United States. The registration details indicate it is owned by an organization involved in technology and networking services.
- WHOIS Data: The owner of the IP is a commercial entity specializing in hosting and cloud services. The registration information is updated regularly, suggesting active management.
Network Activity and Relationships:
- Traffic Patterns: Historical network traffic analysis indicates that this IP address has exhibited both legitimate web service traffic and occasional bursts of data transmission, which could be consistent with both expected user activity and potential data exfiltration attempts.
- Domain Associations: Passive DNS data revealed associations with several domains registered under the same entity. Some of these domains are active and host legitimate websites, while others have been flagged for hosting phishing sites in the past.
- Threat Intelligence Correlation: The IP has been listed in multiple threat intelligence databases as being associated with suspicious activities, including hosting malware or phishing pages, though no direct malicious activity has been definitively linked to it in recent months.
Neighborhood Analysis:
- Subnet Examination: The subnet to which this IP belongs includes a mix of IPs with both reputable and questionable reputations. Several IPs within the same subnet have been flagged for hosting command-and-control (C2) servers, indicating a possible presence of threat actors in the vicinity.
- Proximity to Known Threats: Close analysis of neighboring IPs reveals several known malicious IPs that have historically engaged in DDoS attacks and botnet activities. This proximity suggests a higher risk of the IP being targeted or exploited for malicious purposes.
Behavioral Observations:
- Recent Activity: Network scans have shown an increase in outbound connections from this IP, some of which appear to be directed towards known malicious IPs or data centers known for hosting illicit activities.
- Incident Reports: There have been anecdotal reports from organizations indicating that connections to this IP have been observed during security incidents, though these have not been conclusively linked to any specific event or campaign.
Conclusion and Recommendations:
The IP address 123.207.53.245/32 exhibits characteristics that warrant close monitoring due to its associations with both legitimate services and potential security threats. Given its historical and recent activity patterns, the following actions are recommended for SOC teams:
1. Continuous Monitoring: Implement continuous network traffic monitoring for this IP to detect and respond to any anomalous behavior promptly.
2. Threat Intelligence Integration: Regularly update threat intelligence feeds to include data on associated domains and neighboring IPs to enhance situational awareness.
3. Incident Response Preparedness: Prepare incident response protocols in case this IP is implicated in future security incidents, including predefined mitigation steps.
4. Collaboration: Engage with the broader cybersecurity community to share intelligence and insights related to this IP and its associated domains.
